When stars cannot burn anymore, they make a huge explosion. But when PSR B1257+12 exploded, there were surviving planets. Watch the whole thing for more, or go to wikipedia.org/wiki/PSR_B1257%2B12.
Radio signals from the pulsar PSR B1257+12 in the constellation Virgo led Penn State professor of Astronomy and Astrophysics Alexander Wolszczan to discover the first planets ever known outside our solar system. He discovered the planets in 1991 and confirmed their existence in 1994. Wolszczan used the worlds largest radio telescope in Arecibo, Puerto Rico, to time the radio signals coming from a distant tiny neutron star in the constellation Virgo, 7,000 trillion miles from Earth. These measurements helped him to determine that two of the planets are similar in mass to Earth and the other is about the mass of the Moon. Until Wolszczan's discovery, the only known planets were in our solar system. His work suggests that planets may be more common in the universe than astronomers had previously thought. It will also help astronomers to understand how planets, including Earth, are formed. The planets Wolszczan found probably don't support life because the tiny pulsar they orbit bombards them with deadly radiation. However, his discovery increases the chances that somewhere in the universe planets may exist that, like Earth, are capable of supporting life.

A pulsar (portmanteau of pulsating star) is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can only be observed when the beam of emission is pointing toward the Earth, much the way a lighthouse can only be seen when the light is pointed in the direction of an observer, and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that range from roughly milliseconds to seconds for an individual pulsar.
The events leading to the formation of a pulsar begin when the core of a massive star is compressed during a supernova, which collapses into a neutron star. The neutron star retains most of its angular momentum, and since it has only a tiny fraction of its progenitor's radius (and therefore its moment of inertia is sharply reduced), it is formed with very high rotation speed. A beam of radiation is emitted along the magnetic axis of the pulsar, which spins along with the rotation of the neutron star. The magnetic axis of the pulsar determines the direction of the electromagnetic beam, with the magnetic axis not necessarily being the same as its rotational axis. This misalignment causes the beam to be seen once for every rotation of the neutron star, which leads to the "pulsed" nature of its appearance. The beam originates from the rotational energy of the neutron star, which generates an electrical field from the movement of the very strong magnetic field, resulting in the acceleration of protons and electrons on the star surface and the creation of an electromagnetic beam emanating from the poles of the magnetic field. This rotation slows down over time as electromagnetic power is emitted. When a pulsar's spin period slows down sufficiently, the radio pulsar mechanism is believed to turn off (the so-called "death line"). This turn-off seems to take place after about 10–100 million years, which means of all the neutron stars in the 13.6 billion year age of the universe, around 99% no longer pulsate. The longest known pulsar period is 8.51 seconds.
The precise periods of pulsars make them useful tools. Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. The first extrasolar planets were discovered around a pulsar, PSR B1257+12. Certain types of pulsars rival atomic clocks in their accuracy in keeping time. .

Today Phil explains that YES, there are other planets out there and astonomers have a lot of methods for detecting them. Nearly 2000 have been found so far. The most successful method is using transits, where a planet physically passes in front of its parent star, producing a measurable dip in the star’s light. Another is to measuring the Doppler shift in a star’s light due to reflexive motion as the planet orbits. Exoplanets appear to orbit nearly every kind of star, and we’ve even found planets that are the same size as Earth. We think there may be many billions of Earth-like planets in our galaxy.
This is a reupload of last week's episode to correct an error in the way we covered reflexive motion.
For more information on the change and reflexive motion, you can check out Phil's blog: http://www.slate.com/blogs/bad_astronomy/2015/08/07/crash_course_astronomy_exoplanets.html

Part 47 of a 100 video series.
My Thoughts:
I somehow did these calculations incorrectly a few weeks ago. I corrected them today and found new information in regards to the equation I figured out. I look at the numbers and see what the mathematical fraction is and then I google the answer to see what comes up.
It's fascinating to find that many of the components listed are used for space satellite and rockets for NASA's latest inventions. As well as theories and scientists who have recently "discovered" and written about their tests and findings in 2011.
The data in some cases is just a theory, waiting to be proven. It will be exciting if you can take bits and pieces from the data I am about to share with you. I hope you can build the "faster" space ship and make sure you let me know if its based on any of my calcuations.
The Idea Girl
Search Results from the first equation that turns out to be the wrong one in the end. It's cool what comes up though. Man's first impressions on how to fly from the early 1900s. Thoughts, ideas, dreams and theories written by our early greats in history. People whose thoughts written in the early 17th Century become a reality in January 2012...
I started this project December 2011.
The Idea Girl
My Thoughts
When I started doing this I didn't know ANYTHING about outerspace. Seriously. I look up at the stars each night. I can identify the moon, sirius, Orion's belt, the big and little dipper and that's about it...
Most of this terminology is completely new to me and probably to some of you. We shall learn things as we go along on this journey of almost 100 videos based on some words from a meditation, an ALIEN signal received called "WOW" and my attempts to contact those that live in other Universes just so I can help to prove that they exist once and for all.
Lastly all of this was simply to tap into that "Alien" Intelligience we've all wanted to be a part of and now we can.
Joining forces with our brothers and sisters around the world we can build something altogether. Just as the bible story goes about the Tower of Babel where God says in his holy word "If they all join together as one, nothing can stop them..."
Above are some examples of the types of light and things that SETI and other scientists look for through telescopes, satellite data and more to determine if there are habitable planets out there. To study stars, how they are formed, break apart and when and how evolution began in the Milky Way and our Solar System.
quote
PSR B1257+12, sometimes abbreviated as PSR 1257+12, is a pulsar located roughly 2000 light-years from the Sun. In 2007, it was confirmed that three extrasolar planets orbit the pulsar.

Apparently, many people, when they were still kids, felt unexplained feeling of looking at the night sky.
Curiosity, fascination, attempt to understand the magnitude, or maybe just simple longing for... home?
You can call it a child's imagination, an illusion that passes with age turning into an insignificant anecdote. However, we all have the particles of the stars inside of us. Carbon, oxygen, nitrogen...
Hyperspace is the beginning of my attempts to mental journey back to 'home'. Passing the stars, seeking end by an unknown surrounding emptiness. How does it feel ? Now listen...

Alien Planets Orbiting in Unlikely Manner
An exoplanet or extrasolar planet is a planet that orbits a star other than the Sun, a stellar remnant, or a brown dwarf. Nearly 2000 exoplanets have been discovered (1932 planets in 1222 planetary systems including 484 multiple planetary systems as of 10 July 2015). There are also rogue planets, which do not orbit any star and which tend to be considered separately, especially if they are gas giants, in which case they are often counted, like WISE 0855−0714, as sub-brown dwarfs.
The Kepler space telescope has also detected a few thousand candidate planets, of which about 11% may be false positives. There is at least one planet on average per star. Around 1 in 5 Sun-like stars[a] have an "Earth-sized"[b] planet in the habitable zone,with the nearest expected to be within 12 light-years distance from Earth. Assuming 200 billion stars in the Milky Way,[d] that would be 11 billion potentially habitable Earth-sized planets in the Milky Way, rising to 40 billion if red dwarfs are included. The rogue planets in the Milky Way possibly number in the trillions.
The nearest known exoplanet, if confirmed, would be Alpha Centauri Bb, but there is some doubt about its existence. As of March 2014, the least massive planet known is PSR B1257+12 A, which is about twice the mass of the Moon. The most massive planet listed on the NASA Exoplanet Archive is DENIS-P J082303.1-491201 b, about 29 times the mass of Jupiter, although according to most definitions of a planet, it is too massive to be a planet and may be a brown dwarf instead. There are planets that are so near to their star that they take only a few hours to orbit and there are others so far away that they take thousands of years to orbit. Some are so far out that it is difficult to tell if they are gravitationally bound to the star. Almost all of the planets detected so far are within the Milky Way, but there have also been a few possible detections of extragalactic planets.
The discovery of exoplanets has intensified interest in the search for extraterrestrial life, particularly for those that orbit in the host star's habitable zone where it is possible for liquid water (and therefore life) to exist on the surface. The study of planetary habitability also considers a wide range of other factors in determining the suitability of a planet for hosting life.

Astronomers have been hoping and expecting to find planets around Sun-like stars, so it was a great surprise when the first extrasolar planets were detected around a pulsar. PSR 1257+12 is a dead star, yet it has two Earth-like objects moving in tight orbits around it. The detection of these planets was aided by the high precision radio timing measurements that are possible for a radio emitting pulsar. Pulsars form from the death of a massive star, a supernova, and it is very unlikely that a planetary system could survive such an explosion. So this system did not form in the standard way that our planetary system did. Perhaps these planets formed from the aggregation of debris left over from the supernova. Either way, this exotic and bizarre system is unlikely to tell us much about the formation process of our own solar system.

Radio signals from the pulsar PSR B1257+12 in the constellation Virgo led Penn State professor of Astronomy and Astrophysics Alexander Wolszczan to discover the first planets ever known outside our solar system. He discovered the planets in 1991 and confirmed their existence in 1994. Wolszczan used the worlds largest radio telescope in Arecibo, Puerto Rico, to time the radio signals coming from a distant tiny neutron star in the constellation Virgo, 7,000 trillion miles from Earth. These measurements helped him to determine that two of the planets are similar in mass to Earth and the other is about the mass of the Moon. Until Wolszczan's discovery, the only known planets were in our solar system. His work suggests that planets may be more common in the universe than astronomers had previously thought. It will also help astronomers to understand how planets, including Earth, are formed. The planets Wolszczan found probably don't support life because the tiny pulsar they orbit bombards them with deadly radiation. However, his discovery increases the chances that somewhere in the universe planets may exist that, like Earth, are capable of supporting life. -

A pulsar (portmanteau of pulsating star) is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can only be observed when the beam of emission is pointing toward the Earth, much the way a lighthouse can only be seen when the light is pointed in the direction of an observer, and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that range from roughly milliseconds to seconds for an individual pulsar. The events leading to the formation of a pulsar begin when the core of a massive star is compressed during a supernova, which collapses into a neutron star. The neutron star retains most of its angular momentum, and since it has only a tiny fraction of its progenitor's radius (and therefore its moment of inertia is sharply reduced), it is formed with very high rotation speed. A beam of radiation is emitted along the magnetic axis of the pulsar, which spins along with the rotation of the neutron star. The magnetic axis of the pulsar determines the direction of the electromagnetic beam, with the magnetic axis not necessarily being the same as its rotational axis. This misalignment causes the beam to be seen once for every rotation of the neutron star, which leads to the "pulsed" nature of its appearance. The beam originates from the rotational energy of the neutron star, which generates an electrical field from the movement of the very strong magnetic field, resulting in the acceleration of protons and electrons on the star surface and the creation of an electromagnetic beam emanating from the poles of the magnetic field. This rotation slows down over time as electromagnetic power is emitted. When a pulsar's spin period slows down sufficiently, the radio pulsar mechanism is believed to turn off (the so-called "death line"). This turn-off seems to take place after about 10–100 million years, which means of all the neutron stars in the 13.6 billion year age of the universe, around 99% no longer pulsate. The longest known pulsar period is 8.51 seconds. The precise periods of pulsars make them useful tools. Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. The first extrasolar planets were discovered around a pulsar, PSR B1257+12. Certain types of pulsars rival atomic clocks in their accuracy in keeping time. . . stargazer. -

The most successful method is using transits, where a planet physically passes in front of its parent star, producing a measurable dip in the star’s light. Another is to measuring the Doppler shift in a star’s light due to reflexive motion as the planet orbits. Exoplanets appear to orbit nearly every kind of star, and we’ve even found planets that are the same size as Earth. We think there may be many billions of Earth-like planets in our galaxy.

http://alienspacesciencenews.wordpress.com/ http://theideagirlsays.wordpress.com/ http://victoriastaffordapsychicinvestigation.wordpress.com/ http://www.twitter.com/theideagirl Part 47 of a 100 video series. My Thoughts: I somehow did these calculations incorrectly a few weeks ago. I corrected them today and found new information in regards to the equation I figured out. I look at the numbers and see what the mathematical fraction is and then I google the answer to see what comes up. It's fascinating to find that many of the components listed are used for space satellite and rockets for NASA's latest inventions. As well as theories and scientists who have recently "discovered" and written about their tests and findings in 2011. The data in some cases is just a theory, waiting to be proven. It will be exciting if you can take bits and pieces from the data I am about to share with you. I hope you can build the "faster" space ship and make sure you let me know if its based on any of my calcuations. The Idea Girl Search Results from the first equation that turns out to be the wrong one in the end. It's cool what comes up though. Man's first impressions on how to fly from the early 1900s. Thoughts, ideas, dreams and theories written by our early greats in history. People whose thoughts written in the early 17th Century become a reality in January 2012... I started this project December 2011. The Idea Girl My Thoughts When I started doing this I didn't know ANYTHING about outerspace. Seriously. I look up at the stars each night. I can identify the moon, sirius, Orion's belt, the big and little dipper and that's about it... Most of this terminology is completely new to me and probably to some of you. We shall learn things as we go along on this journey of almost 100 videos based on some words from a meditation, an ALIEN signal received called "WOW" and my attempts to contact those that live in other Universes just so I can help to prove that they exist once and for all. Lastly all of this was simply to tap into that "Alien" Intelligience we've all wanted to be a part of and now we can. Joining forces with our brothers and sisters around the world we can build something altogether. Just as the bible story goes about the Tower of Babel where God says in his holy word "If they all join together as one, nothing can stop them..." Above are some examples of the types of light and things that SETI and other scientists look for through telescopes, satellite data and more to determine if there are habitable planets out there. To study stars, how they are formed, break apart and when and how evolution began in the Milky Way and our Solar System. quote PSR B1257+12, sometimes abbreviated as PSR 1257+12, is a pulsar located roughly 2000 light-years from the Sun. In 2007, it was confirmed that three extrasolar planets orbit the pulsar. -

Apparently, many people, when they were still kids, felt unexplained feeling of looking at the night sky. Curiosity, fascination, attempt to understand the magnitude, or maybe just simple longing for... home? You can call it a child's imagination, an illusion that passes with age turning into an insignificant anecdote. However, we all have the particles of the stars inside of us. Carbon, oxygen, nitrogen... Hyperspace is the beginning of my attempts to mental journey back to 'home'. Passing the stars, seeking end by an unknown surrounding emptiness. How does it feel ?

What?! An Alien Yoyo Planet? - Documentary Channel 31What?! An Alien Yoyo Planet? - Documentary Channel 31
Alien Yoyo Planet - Documentary Channel 31 Alien Planets Orbiting in Unlikely Manner An exoplanet or extrasolar planet is a planet that orbits a star other than the Sun, a stellar remnant, or a brown dwarf. Nearly 2000 exoplanets have been discovered (1932 planets in 1222 planetary systems including 484 multiple planetary systems as of 10 July 2015). There are also rogue planets, which do not orbit any star and which tend to be considered separately, especially if they are gas giants, in which case they are often counted, like WISE 0855−0714, as sub-brown dwarfs. The Kepler space telescope has also detected a few thousand candidate planets, of which about 11% may be false positives. There is at least one planet on average per star. Around 1 in 5 Sun-like stars[a] have an "Earth-sized"[b] planet in the habitable zone,with the nearest expected to be within 12 light-years distance from Earth. Assuming 200 billion stars in the Milky Way,[d] that would be 11 billion potentially habitable Earth-sized planets in the Milky Way, rising to 40 billion if red dwarfs are included. The rogue planets in the Milky Way possibly number in the trillions. The nearest known exoplanet, if confirmed, would be Alpha Centauri Bb, but there is some doubt about its existence. As of March 2014, the least massive planet known is PSR B1257+12 A, which is about twice the mass of the Moon. The most massive planet listed on the NASA Exoplanet Archive is DENIS-P J082303.1-491201 b, about 29 times the mass of Jupiter, although according to most definitions of a planet, it is too massive to be a planet and may be a brown dwarf instead. There are planets that are so near to their star that they take only a few hours to orbit and there are others so far away that they take thousands of years to orbit. Some are so far out that it is difficult to tell if they are gravitationally bound to the star. Almost all of the planets detected so far are within the Milky Way, but there have also been a few possible detections of extragalactic planets. The discovery of exoplanets has intensified interest in the search for extraterrestrial life, particularly for those that orbit in the host star's habitable zone where it is possible for liquid water (and therefore life) to exist on the surface. The study of planetary habitability also considers a wide range of other factors in determining the suitability of a planet for hosting life.

Teach Astronomy - Pulsar PlanetsTeach Astronomy - Pulsar Planets
http://www.teachastronomy.com/ Astronomers have been hoping and expecting to find planets around Sun-like stars, so it was a great surprise when the first extrasolar planets were detected around a pulsar. PSR 1257+12 is a dead star, yet it has two Earth-like objects moving in tight orbits around it. The detection of these planets was aided by the high precision radio timing measurements that are possible for a radio emitting pulsar. Pulsars form from the death of a massive star, a supernova, and it is very unlikely that a planetary system could survive such an explosion. So this system did not form in the standard way that our planetary system did. Perhaps these planets formed from the aggregation of debris left over from the supernova. Either way, this exotic and bizarre system is unlikely to tell us much about the formation process of our own solar system.

Planets survived supernova!!! (PSR B1257+12)
When stars cannot burn anymore, they make a huge explosion. But when PSR B1257+12 exploded, there were surviving planets. Watch the whole thing for more, or go to wikipedia.org/wiki/PSR_B1257%2B12. -
PSR B1257+12
Radio signals from the pulsar PSR B1257+12 in the constellation Virgo led Penn State professor of Astronomy and Astrophysics Alexander Wolszczan to discover the first planets ever known outside our solar system. He discovered the planets in 1991 and confirmed their existence in 1994. Wolszczan used the worlds largest radio telescope in Arecibo, Puerto Rico, to time the radio signals coming from a distant tiny neutron star in the constellation Virgo, 7,000 trillion miles from Earth. These measurements helped him to determine that two of the planets are similar in mass to Earth and the other is about the mass of the Moon. Until Wolszczan's discovery, the only known planets were in our solar system. His work suggests that planets may be more common in the universe than astronomers had previou... -
An introduction to Pulsars - Pulsars and Quasars
A pulsar (portmanteau of pulsating star) is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can only be observed when the beam of emission is pointing toward the Earth, much the way a lighthouse can only be seen when the light is pointed in the direction of an observer, and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that range from roughly milliseconds to seconds for an individual pulsar. The events leading to the formation of a pulsar begin when the core of a massive star is compressed during a supernova, which collapses into a neutron star. The neutron star retains most of its angular momentum,... -
Exoplanets: Crash Course Astronomy #27
Today Phil explains that YES, there are other planets out there and astonomers have a lot of methods for detecting them. Nearly 2000 have been found so far. The most successful method is using transits, where a planet physically passes in front of its parent star, producing a measurable dip in the star’s light. Another is to measuring the Doppler shift in a star’s light due to reflexive motion as the planet orbits. Exoplanets appear to orbit nearly every kind of star, and we’ve even found planets that are the same size as Earth. We think there may be many billions of Earth-like planets in our galaxy. This is a reupload of last week's episode to correct an error in the way we covered reflexive motion. For more information on the change and reflexive motion, you can check out Phil's blog: h... -

Radio signals from the pulsar PSR B1257+12 in the constellation Virgo led Penn State professor of Astronomy and Astrophysics Alexander Wolszczan to discover the first planets ever known outside our solar system. He discovered the planets in 1991 and confirmed their existence in 1994. Wolszczan used the worlds largest radio telescope in Arecibo, Puerto Rico, to time the radio signals coming from a distant tiny neutron star in the constellation Virgo, 7,000 trillion miles from Earth. These measurements helped him to determine that two of the planets are similar in mass to Earth and the other is about the mass of the Moon. Until Wolszczan's discovery, the only known planets were in our solar system. His work suggests that planets may be more common in the universe than astronomers had previously thought. It will also help astronomers to understand how planets, including Earth, are formed. The planets Wolszczan found probably don't support life because the tiny pulsar they orbit bombards them with deadly radiation. However, his discovery increases the chances that somewhere in the universe planets may exist that, like Earth, are capable of supporting life.

A pulsar (portmanteau of pulsating star) is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can only be observed when the beam of emission is pointing toward the Earth, much the way a lighthouse can only be seen when the light is pointed in the direction of an observer, and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that range from roughly milliseconds to seconds for an individual pulsar.
The events leading to the formation of a pulsar begin when the core of a massive star is compressed during a supernova, which collapses into a neutron star. The neutron star retains most of its angular momentum, and since it has only a tiny fraction of its progenitor's radius (and therefore its moment of inertia is sharply reduced), it is formed with very high rotation speed. A beam of radiation is emitted along the magnetic axis of the pulsar, which spins along with the rotation of the neutron star. The magnetic axis of the pulsar determines the direction of the electromagnetic beam, with the magnetic axis not necessarily being the same as its rotational axis. This misalignment causes the beam to be seen once for every rotation of the neutron star, which leads to the "pulsed" nature of its appearance. The beam originates from the rotational energy of the neutron star, which generates an electrical field from the movement of the very strong magnetic field, resulting in the acceleration of protons and electrons on the star surface and the creation of an electromagnetic beam emanating from the poles of the magnetic field. This rotation slows down over time as electromagnetic power is emitted. When a pulsar's spin period slows down sufficiently, the radio pulsar mechanism is believed to turn off (the so-called "death line"). This turn-off seems to take place after about 10–100 million years, which means of all the neutron stars in the 13.6 billion year age of the universe, around 99% no longer pulsate. The longest known pulsar period is 8.51 seconds.
The precise periods of pulsars make them useful tools. Observations of a pulsar in a binary neutron star system were used to indirectly confirm the existence of gravitational radiation. The first extrasolar planets were discovered around a pulsar, PSR B1257+12. Certain types of pulsars rival atomic clocks in their accuracy in keeping time. .

Today Phil explains that YES, there are other planets out there and astonomers have a lot of methods for detecting them. Nearly 2000 have been found so far. The most successful method is using transits, where a planet physically passes in front of its parent star, producing a measurable dip in the star’s light. Another is to measuring the Doppler shift in a star’s light due to reflexive motion as the planet orbits. Exoplanets appear to orbit nearly every kind of star, and we’ve even found planets that are the same size as Earth. We think there may be many billions of Earth-like planets in our galaxy.
This is a reupload of last week's episode to correct an error in the way we covered reflexive motion.
For more information on the change and reflexive motion, you can check out Phil's blog: http://www.slate.com/blogs/bad_astronomy/2015/08/07/crash_course_astronomy_exoplanets.html

Part 47 of a 100 video series.
My Thoughts:
I somehow did these calculations incorrectly a few weeks ago. I corrected them today and found new information in regards to the equation I figured out. I look at the numbers and see what the mathematical fraction is and then I google the answer to see what comes up.
It's fascinating to find that many of the components listed are used for space satellite and rockets for NASA's latest inventions. As well as theories and scientists who have recently "discovered" and written about their tests and findings in 2011.
The data in some cases is just a theory, waiting to be proven. It will be exciting if you can take bits and pieces from the data I am about to share with you. I hope you can build the "faster" space ship and make sure you let me know if its based on any of my calcuations.
The Idea Girl
Search Results from the first equation that turns out to be the wrong one in the end. It's cool what comes up though. Man's first impressions on how to fly from the early 1900s. Thoughts, ideas, dreams and theories written by our early greats in history. People whose thoughts written in the early 17th Century become a reality in January 2012...
I started this project December 2011.
The Idea Girl
My Thoughts
When I started doing this I didn't know ANYTHING about outerspace. Seriously. I look up at the stars each night. I can identify the moon, sirius, Orion's belt, the big and little dipper and that's about it...
Most of this terminology is completely new to me and probably to some of you. We shall learn things as we go along on this journey of almost 100 videos based on some words from a meditation, an ALIEN signal received called "WOW" and my attempts to contact those that live in other Universes just so I can help to prove that they exist once and for all.
Lastly all of this was simply to tap into that "Alien" Intelligience we've all wanted to be a part of and now we can.
Joining forces with our brothers and sisters around the world we can build something altogether. Just as the bible story goes about the Tower of Babel where God says in his holy word "If they all join together as one, nothing can stop them..."
Above are some examples of the types of light and things that SETI and other scientists look for through telescopes, satellite data and more to determine if there are habitable planets out there. To study stars, how they are formed, break apart and when and how evolution began in the Milky Way and our Solar System.

Alien Yoyo Planet - Documentary Channel 31
Alien Planets Orbiting in Unlikely Manner
An exoplanet or extrasolar planet is a planet that orbits a star other than the Sun, a stellar remnant, or a brown dwarf. Nearly 2000 exoplanets have been discovered (1932 planets in 1222 planetary systems including 484 multiple planetary systems as of 10 July 2015). There are also rogue planets, which do not orbit any star and which tend to be considered separately, especially if they are gas giants, in which case they are often counted, like WISE 0855−0714, as sub-brown dwarfs.
The Kepler space telescope has also detected a few thousand candidate planets, of which about 11% may be false positives. There is at least one planet on average per star. Around 1 in 5 Sun-like stars[a] have an "Earth-sized"[b] planet in the habitable zone,with the nearest expected to be within 12 light-years distance from Earth. Assuming 200 billion stars in the Milky Way,[d] that would be 11 billion potentially habitable Earth-sized planets in the Milky Way, rising to 40 billion if red dwarfs are included. The rogue planets in the Milky Way possibly number in the trillions.
The nearest known exoplanet, if confirmed, would be Alpha Centauri Bb, but there is some doubt about its existence. As of March 2014, the least massive planet known is PSR B1257+12 A, which is about twice the mass of the Moon. The most massive planet listed on the NASA Exoplanet Archive is DENIS-P J082303.1-491201 b, about 29 times the mass of Jupiter, although according to most definitions of a planet, it is too massive to be a planet and may be a brown dwarf instead. There are planets that are so near to their star that they take only a few hours to orbit and there are others so far away that they take thousands of years to orbit. Some are so far out that it is difficult to tell if they are gravitationally bound to the star. Almost all of the planets detected so far are within the Milky Way, but there have also been a few possible detections of extragalactic planets.
The discovery of exoplanets has intensified interest in the search for extraterrestrial life, particularly for those that orbit in the host star's habitable zone where it is possible for liquid water (and therefore life) to exist on the surface. The study of planetary habitability also considers a wide range of other factors in determining the suitability of a planet for hosting life.

http://www.teachastronomy.com/
Astronomers have been hoping and expecting to find planets around Sun-like stars, so it was a great surprise when the first extrasolar planets were detected around a pulsar. PSR 1257+12 is a dead star, yet it has two Earth-like objects moving in tight orbits around it. The detection of these planets was aided by the high precision radio timing measurements that are possible for a radio emitting pulsar. Pulsars form from the death of a massive star, a supernova, and it is very unlikely that a planetary system could survive such an explosion. So this system did not form in the standard way that our planetary system did. Perhaps these planets formed from the aggregation of debris left over from the supernova. Either way, this exotic and bizarre system is unlikely to tell us much about the formation process of our own solar system.

Neutron star
A neutron star is a type of stellar remnant that can result from the gravitational collapse of a massive star during a Type II, Type Ib or Type Ic supernova event. Neutron stars are the densest and tiniest stars known to exist in the universe; although having only the radius of about 10 km (6 mi), they may have a mass of a few times that of the Sun. Neutron stars probably appear white to the naked eye. Neutron stars are the end points of stars whose inert core's mass after nuclear burning is greater than the Chandrasekhar limit for white dwarfs, but whose mass is not great enough to overcome the neutron degeneracy pressure to become black holes. Such stars are composed almost entirely of neutrons, which are subatomic particles without net electrical charge and with slightly larger mass tha... -

Discoveries of exoplanets
An exoplanet (extrasolar planet) is a planet located outside the Solar System. The first confirmation of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found in a four-day orbit around the nearby star 51 Pegasi. Some exoplanets have been imaged directly by telescopes, but the vast majority have been detected through indirect methods such as the transit method and the radial-velocity method. As of November 20, 2014, astronomers have identified 1850 such planets (in 1160 planetary systems and 472 multiple planetary systems). This is a list of the most notable discoveries.

Rosseland Lecture 2015 - Making, baking and breaking: Dust in the interstellar medium
This year’s Rosseland Lecture was held by Anja C. Andersen, associate Professor at Dark Cosmology Centre, Niels Bohr Institute, University of Copenhagen. Dust grains are found everywhere in the space between the stars in galaxies. They are responsible for the formation of molecular hydrogen and for absorbing and re-emitting about 50% of the energy from all galaxies, as well as providing an effective coolant for star formation. Although important in various astrophysical processes, the origin and consequently the chemical make-up and emission properties of dust grains is largely unknown. Dust is generally believed to form in the atmospheres of low/intermediate-mass stars late in life, but there is growing evidence that dust may also be formed in the explosions of massive stars and/or be ac...

Se denomina planeta extrasolar o exoplaneta a un planeta que orbita una estrella diferente al Sol y que, por tanto, no pertenece al Sistema Solar. Los exoplanetas se convirtieron en objeto de investigación científica en el siglo XX. Muchos astrónomos suponían su existencia, pero carecían de medios para identificarlos. La primera detección confirmada se hizo en 1992, con el descubrimiento de varios planetas de masa terrestre orbitando el púlsar PSR B1257+12.La primera detección confirmada de un planeta extrasolar orbitando alrededor de una estrella de la secuencia principal (51 Pegasi b), se hizo en 1995 por los astrónomos Michel Mayor y Didier Queloz. Desde entonces el número de hallazgos ha crecido año tras año.Se han descubierto 1195 sistemas planetarios que contienen un total de 1897 cuerpos planetarios, 478 de estos sistemas son múltiples y 43 de estos planetas están por encima de las 13 MJ (1 MJ es la masa de Júpiter) por lo que muy probablemente sean enanas marrones.

La NASA adelantó en junio de 2010 que la Sonda Kepler, puesta en órbita en marzo de 2009, detectó indicios de 706 exoplanetas nuevos en sus primeros 43 días de funcionamiento, 400 de los cuales tienen dimensiones entre las de Neptuno y la Tierra. Los resultados oficiales de esta misión serán publicados en febrero de 2011, pero los resultados provisionales indican que al menos 60 de los planetas detectados tendrán un tamaño similar al de la Tierra (el doble del tamaño terrestre, o menos).
El exoplaneta confirmado más similar a la Tierra descubierto orbitando dentro de la zona habitable es, hasta enero de 2015, Kepler-438b, con un índice de similitud con la Tierra del 88%. KOI-4878.01, un candidato a planeta, posee un IST mayor (98%).De confirmarse su presencia, sería un posible análogo a la Tierra.
El 12 de enero de 2012, la revista Nature publica un artículo desarrollado por científicos internacionales donde utilizando el método de microlentes gravitacionales se asegura que toda estrella de la Vía Láctea debe poseer entre 0,71 y 2,32 planetas orbitando.

Se denomina planeta extrasolar o exoplaneta a un planeta que orbita una estrella diferente al Sol y que, por tanto, no pertenece al Sistema Solar. Los exoplanetas se convirtieron en objeto de investigación científica en el siglo XX. Muchos astrónomos suponían su existencia, pero carecían de medios para identificarlos. La primera detección confirmada se hizo en 1992, con el descubrimiento de varios planetas de masa terrestre orbitando el púlsar PSR B1257+12.La primera detección confirmada de un planeta extrasolar orbitando alrededor de una estrella de la secuencia principal (51 Pegasi b), se hizo en 1995 por los astrónomos Michel Mayor y Didier Queloz. Desde entonces el número de hallazgos ha crecido año tras año.Se han descubierto 1195 sistemas planetarios que contienen un total de 1897 cuerpos planetarios, 478 de estos sistemas son múltiples y 43 de estos planetas están por encima de las 13 MJ (1 MJ es la masa de Júpiter) por lo que muy probablemente sean enanas marrones.

A neutron star is a type of stellar remnant that can result from the gravitational collapse of a massive star during a Type II, Type Ib or Type Ic supernova event. Neutron stars are the densest and tiniest stars known to exist in the universe; although having only the radius of about 10 km (6 mi), they may have a mass of a few times that of the Sun. Neutron stars probably appear white to the naked eye.
Neutron stars are the end points of stars whose inert core's mass after nuclear burning is greater than the Chandrasekhar limit for white dwarfs, but whose mass is not great enough to overcome the neutron degeneracy pressure to become black holes. Such stars are composed almost entirely of neutrons, which are subatomic particles without net electrical charge and with slightly larger mass than protons. Neutron stars are very hot and are supported against further collapse by quantum degeneracy pressure due to the phenomenon described by the Pauli exclusion principle. This principle states that no two neutrons (or any other fermionic particles) can occupy the same place and quantum state simultaneously.

An exoplanet (extrasolar planet) is a planet located outside the Solar System. The first confirmation of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found in a four-day orbit around the nearby star 51 Pegasi. Some exoplanets have been imaged directly by telescopes, but the vast majority have been detected through indirect methods such as the transit method and the radial-velocity method. As of November 20, 2014, astronomers have identified 1850 such planets (in 1160 planetary systems and 472 multiple planetary systems). This is a list of the most notable discoveries.

This year’s Rosseland Lecture was held by Anja C. Andersen, associate Professor at Dark Cosmology Centre, Niels Bohr Institute, University of Copenhagen.
Dust grains are found everywhere in the space between the stars in galaxies. They are responsible for the formation of molecular hydrogen and for absorbing and re-emitting about 50% of the energy from all galaxies, as well as providing an effective coolant for star formation. Although important in various astrophysical processes, the origin and consequently the chemical make-up and emission properties of dust grains is largely unknown. Dust is generally believed to form in the atmospheres of low/intermediate-mass stars late in life, but there is growing evidence that dust may also be formed in the explosions of massive stars and/or be accreted in large amounts in the interstellar medium.
