The artist's concept depicts Kepler-186f , the first validated Earth-size planet to orbit a distant star in the habitable zone.

Astronomers have discovered what they say is the most Earth-like planet yet detected - a distant, rocky world that is similar in size to our planet and orbiting in a life-friendly zone around a distant star. The find, announced on Thursday, excited planet hunters who have been scouring the Milky Way galaxy for years for potentially habitable spots outside our solar system. It is in what astronomers call the "Goldilocks zone" where it is not too hot or not too cold for life. The planet was detected by NASA's orbiting Kepler telescope, which examines the heavens for subtle changes in brightness that indicate an...more »

"April 17, 2014. Using NASA's Kepler Space Telescope, astronomers have discovered the first Earth-size planet orbiting a star in the "habitable zone" -- the range of distance from a star where liquid water might pool on the surface of an orbiting planet. The discovery of Kepler-186f confirms that planets the size of Earth exist in the habitable zone of stars other than our sun. While planets have previously been found in the habitable zone, they are all at least 40 percent larger in size than Earth, and understanding their makeup is challenging. Kepler-186f is more reminiscent of Earth. "The discovery of Kepler-186f is a significant step toward finding worlds like our planet Earth," said Paul Hertz, NASA's Astrophysics Division director at the agency's headquarters in Washington. "Future NASA missions, like the Transiting Exoplanet Survey Satellite and the James Webb Space Telescope, will discover the nearest rocky exoplanets and determine their composition and atmospheric conditions, continuing humankind's quest to find truly Earth-like worlds." Although the size of Kepler-186f is known, its mass and composition are not. Previous research, however, suggests that a planet the size of Kepler-186f is likely to be rocky. "We know of just one planet where life exists -- Earth. When we search for life outside our solar system, we focus on finding planets with characteristics that mimic that of Earth," said Elisa Quintana, research scientist at the SETI Institute at NASA's Ames Research Center in Moffett Field, Calif., and lead author of the paper published today in the journal Science. "Finding a habitable zone planet comparable to Earth in size is a major step forward." Kepler-186f resides in the Kepler-186 system, about 500 light-years from Earth in the constellation Cygnus. The system is also home to four companion planets, which orbit a star half the size and mass of our sun. The star is classified as an M dwarf, or red dwarf, a class of stars that makes up 70 percent of the stars in the Milky Way galaxy. "M dwarfs are the most numerous stars," said Quintana. "The first signs of other life in the galaxy may well come from planets orbiting an M dwarf." Kepler-186f orbits its star once every 130 days and receives one-third the energy from its star that Earth gets from the sun, placing it nearer the outer edge of the habitable zone. On the surface of Kepler-186f, the brightness of its star at high noon is only as bright as our sun appears to us about an hour before sunset. "Being in the habitable zone does not mean we know this planet is habitable. The temperature on the planet is strongly dependent on what kind of atmosphere the planet has," said Thomas Barclay, research scientist at the Bay Area Environmental Research Institute at Ames, and co-author of the paper. "Kepler-186f can be thought of as an Earth-cousin rather than an Earth-twin. It has many properties that resemble Earth." The four companion planets, Kepler-186b, Kepler-186c, Kepler-186d and Kepler-186e, whiz around their sun every four, seven, 13 and 22 days, respectively, making them too hot for life as we know it. These four inner planets all measure less than 1.5 times the size of Earth. The next steps in the search for distant life include looking for true Earth-twins -- Earth-size planets orbiting within the habitable zone of a sun-like star -- and measuring their chemical compositions. The Kepler Space Telescope, which simultaneously and continuously measured the brightness of more than 150,000 stars, is NASA's first mission capable of detecting Earth-size planets around stars like our sun. Ames is responsible for Kepler's ground system development, mission operations, and science data analysis. NASA's Jet Propulsion Laboratory in Pasadena, Calif., managed Kepler mission development. Ball Aerospace & Technologies Corp. in Boulder, Colo., developed the Kepler flight system and supports mission operations with the Laboratory for Atmospheric and Space Physics at the University of Colorado in Boulder. The Space Telescope Science Institute in Baltimore archives, hosts and distributes Kepler science data.

Kepler-186

This artist's movie illustrates Kepler-186, a five-planet system located about 500 light-years from Earth in the constellation Cygnus, from an overhead view. The green circular band depicts the habitable zone-a range of distances from a star where liquid water might pool on the planet's surface. The blue streak shown in the habitable zone depicts the orbital path of Kepler-186f -- the first validated habitable-zone, Earth-size planet around another star. Kepler-186f orbits its star once every 130 days and receives one-third the energy that Earth does from the sun, placing it near the outer edge of the habitable zone. Kepler-186f is less than ten percent larger than Earth in size, but its mass, composition and density are not known. While scientists don't know the density of the planet, previous research suggests that a planet the size of Kepler-186f is likely to be rocky. This video contains no sound.

Kepler-186f, The Most 'Earth Like' Planet Ever Found

Meet "Kepler-186f", the most 'Earth-like' planet ever found "Kepler-186f", the first Earth-size Planet in the Habitable Zone Newfound Earth-Like Planet, Kepler-186f, Is 'Best Case' For Hosting Life, Astronomers Say The artist's concept depicts Kepler-186f , the first validated Earth-size planet to orbit a distant star in the habitable zone—a range of distance from a star where liquid water might pool on the planet's surface. The discovery of Kepler-186f confirms that Earth-size planets exist in the habitable zones of other stars and signals a significant step closer to finding a world similar to Earth. The size of Kepler-186f is known to be less than ten percent larger than Earth, but its mass, composition and density are not known. Previous research suggests that a planet the size of Kepler-186f is likely to be rocky. Prior to this discovery, the "record holder" for the most "Earth-like" planet went to Kepler-62f, which is 40 percent larger than the size of Earth and orbits in its star's habitable zone. Kepler-186f orbits its star once every 130 days and receives one-third the energy that Earth does from the sun, placing it near the outer edge of the habitable zone. If you could stand on the surface of Kepler-186f, the brightness of its star at high noon would appear as bright as our sun is about an hour before sunset on Earth. Kepler-186f resides in the Kepler-186 system about 500 light-years from Earth in the constellation Cygnus. The system is also home to four inner planets, seen lined up in orbit around a host star that is half the size and mass of the sun. The artistic concept of Kepler-186f is the result of scientists and artists collaborating to imagine the appearance of these distant worlds. Read more about Kepler-186f

Kepler 186f - New Earth-Size Planet Could Have Water

Planet-hunters think they have evidence of a planet about Earth's size -- that could have liquid water -- in orbit around another star.

Intelligent Mouthbrooder-Life on the Terrestrial Planet Alpha Centauri Bc "Nippy"

Intelligent alien life could be already found by 2014. Theoretical studies on the detectability via radial velocity analysis have shown that a dedicated campaign of high-cadence observations with a 1-m class telescope can reliably detect a hypothetical exoplanet "Alpha Centauri Bc (Nippy)" of 1.8 Earth masses in the habitable zone of Alpha Centauri B (orange dwarf) within six months! An "Extraterrestrial Intelligence (ETI)" seems to be found. Alexander Amelkin (Munich) has received in his lucid dreams the signals of extraterrestrial origin from intelligent Mouthbrooder-Life existing on the Terrestrial Planet Alpha Centauri Bc "Nippy": a picture of an intelligent Mouthbrooder and an extraterrestrial music.

The rocky planet, Kepler 186f, is close to the size of Earth and has the potential to hold liquid water, which is critical for life, the team says. Nestled in the Milky Way, it is part of a five-planet system that orbits around a cool dwarf star. It was spotted by the Kepler telescope, which has found nearly 1,000 new worlds since its launch in 2009. "This is the smallest planet we've found so far in the habitable zone," said Prof Stephen Kane, an astrophysicist from San Francisco State University, US. Kepler 186f is about 500 light-years away from the Earth. The researchers estimate that is a little bigger than our planet, with a radius that is about 10% larger than ours. Because of its size, the team believes it is a rocky planet. Prof Kane explained: "There seems to be a transition that occurs at about 1.5 times the Earth's radius, such that if the planet is larger, then it starts to develop a very substantial atmosphere very similar to what we see in the gas giant planets in our own Solar System. The team believes that it has the potential to hold water because with this orbital path it does not journey too close to its star for the liquid to boil away or so far out that it would freeze. Scientists call this region the "habitable zone".

NASA's Kepler Telescope Discovers First Earth-Size Planet

The hunt for potential life in outer space has taken a step forward - an international team of researchers has discovered the first Earth-sized planet within the "habitable zone" of another star. The exoplanet dubbed Kepler-186f was first spotted by scientists using NASA's Kepler telescope, according to research published Thursday in the US journal Science. The exoplanet, located some 500 light years from Earth, orbits in what is seen as the sweet spot around its star: not too close and not too far, so it could have liquid water, considered a crucial component to possibly hosting life. "The discovery of Kepler-186f is a significant step toward finding worlds like our planet Earth," said Paul Hertz, NASA's Astrophysics Division director at the agency's headquarters in Washington. "What makes this finding particularly compelling is that this Earth-sized planet, one of five orbiting this star, which is cooler than the Sun, resides in a temperate region where water could exist in liquid form," said Elisa Quintana of the SETI Institute at NASA's Ames Research Center in California, the lead author of the paper published in Science. Kepler-186f is around 1.1-times the size of Earth - which researchers say is key to predicting the composition of the surface and its atmosphere. When planets are 1.5 times the size of Earth or larger, many of them seem to attract a thick hydrogen and helium layer that makes them start to resemble gas giants like Jupiter or Saturn. Kepler-186f is the fifth and outermost planet orbiting the Kepler-186 star, right on the far edge of that solar system's habitable zone, meaning the surface temperature might not be warm enough to stop water from freezing. "However, it is also slightly larger than the Earth, and so the hope would be that this would result in a thicker atmosphere that would provide extra insulation," explained San Francisco State University astronomer Stephen Kane, another member of the team behind the discovery. Tracking 'transits' Scientists using the NASA's Kepler telescope first discovered it by tracking "transits" - shadows that cross in front of the star. The finding was confirmed by observations from the W.M. Keck and Gemini Observatories. "The discovery of planets with Earth-like properties is one important link in the chain required to answer" whether life can exist on other planets, said co-author Fred Adams, an astronomer at the University of Michigan. "And the discovery of the planet Kepler-186f is an important step toward finding a planet that is like our Earth," he added. But current technology does not allow astronomers to see the celestial body directly or do any analysis to determine its atmosphere or composition. "Some people call these habitable planets, which of course we have no idea if they are," said Kane. "We simply know that they are in the habitable zone, and that is the best place to start looking for habitable planets."

Have we finally found EARTH 2.0? Astronomers discover first same-size planet

Have we finally found EARTH 2.? Astronomers discover first same-size planet in habitable zone that could support alien life The first Earth-sized world in the habitable zone of a star has been found Kepler-186f is 1.1 times the size of Earth and orbits its star in 130 days The discovery was made by a team of scientists using the Kepler telescope It could be the first planet found outside our solar system with liquid water And it is the most likely place for alien life to exist that's been found so far. For decades astronomers have been searching for a world like our own outside the solar system that could host alien life. And now astronomers have announced that they have found one - a planet 1.1 times the size of Earth orbiting a star just 490 light years away. Called Kepler-186f, the planet is the first to be discovered with the right conditions for liquid water to exist on its surface, meaning it could support alien life as well. The find was made by a team of astronomers led by Elisa Quintana of the SETI Institute at Nasa Ames Research Center, who pored through planetary data from Nasa's Kepler space telescope. To date, the telescope has found hundreds of planets, but most are uninhabitable worlds that are either too large or orbit too close to their host star to support life. The discovery of Kepler-186f, therefore, is a big milestone in the field of planet hunting. It is the fifth and outermost world of the planetary system around red dwarf star Kepler-186 and is almost certainly a rocky planet. The find is significant because it is the first Earth-sized world we've found in the habitable zone of a star. Habitable zones, also known as 'Goldilocks zones', are regions around a star where the temperature is just right for water to form. Earth, for example, sits almost bang in the middle of our sun's habitable zone. Although previously we have found exoplanets (worlds outside the solar system) in these zones, none have been the same size as Earth. As our planet is known to have life, it stands to reason that a similar planet may also be habitable. This could make Kepler-186f the first world we've found that might host life as we know it. Taking our planet as an example, water is pretty important for life,' Dr Steve Howell, one of the lead authors on the study that found Kepler-186f and a scientist on the Kepler mission, tells MailOnline. This makes the discovery of a planet that could have water all the more important. 'Kepler 186f will likely provide our first opportunity to search for alien life beyond the solar system.' The planet orbits an M-type dwarf star, one that is slightly dimmer than our own sun, making its habitable zone hug it slightly tighter. But Kepler-186f is on a slightly different orbit than Earth, taking 130 days to make it around the star. This places it towards the edge of the habitable zone of Kepler-186. The other four planets in the system have orbits lasting three to 21 days, making them inhospitable. 'Kepler-186f is at the right distance from the star for water to form,' Thomas Barclay, a research scientist on the Kepler mission and another author on the paper announcing the discovery of the planet, tells MailOnline. Barclay was involved in modelling the planet and discerning what we think it could look like, as shown in the artist's impressions. 'We looked at the kind of light coming from the star, which is slightly redder than our sun,' he explains. 'So we tried to cover the planet in the right colour light, so the planet looks slightly more orangey. 'We tried to work out what sort of colour the ocean would be, so with less blue light the oceans would be duller, not a bright blue like our own planet. 'Then we have the clouds and ice, which are very reasonable assumptions to exist if there's an atmosphere. 'These would reflect the same colour as the star -- our clouds are white because the sun is white. 'So on Kepler-186f they would appear orangey and red.' While it's known the planet is in the habitable zone, astronomers can't be sure with absolute certainty it has water. Extrapolating on what we know from Earth, however, Kepler-186f is a prime candidate for being a world with oceans and seas. That would be dependent on it having an atmosphere, though. 'If we didn't have an atmosphere, we wouldn't have liquid water,' says Barclay. 'It blankets us and traps heat. The same would happen on Kepler-186f.' And if there is plant life on this planet, Barclay says it would again be different to what we have on Earth. 'We did think about what colour the plant life might be due to photosynthesis. 'The best guess is they would be more yellow, due to the different colour of the star. 'The plants would be yellow because it's to do with the energy coming in and being reflected.
