Astronomy, a natural science, is the study of celestial objects (such as stars, galaxies, planets, moons, asteroids, comets and nebulae) and processes (such as supernovae explosions, gamma ray bursts, and cosmic microwave background radiation), the physics, chemistry, and evolution of such objects and processes, and more generally all phenomena that originate outside the atmosphere of Earth. A related but distinct subject, physical cosmology, is concerned with studying the Universe as a whole.
Astronomy is one of the oldest sciences. The early civilizations in recorded history, such as the Babylonians, Greeks, Indians, Egyptians, Nubians, Iranians, Chinese, and Maya performed methodical observations of the night sky. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy and the making of calendars, but professional astronomy is nowadays often considered to be synonymous with astrophysics.
Neil deGrasse Tyson (/ˈniːəl dəˈɡræs ˈtaɪsən/; born October 5, 1958) is an American astrophysicist, cosmologist, author, and science communicator. Since 1996, he has been the Frederick P. Rose Director of the Hayden Planetarium at the Rose Center for Earth and Space in New York City. The center is part of the American Museum of Natural History, where Tyson founded the Department of Astrophysics in 1997 and has been a research associate in the department since 2003.
Born in New York City, Tyson became interested in astronomy at the age of nine after a visit to the Hayden Planetarium. After graduating from the Bronx High School of Science, where he was editor-in-chief of the Physical Science Journal, he completed a bachelor's degree in physics at Harvard University in 1980. After receiving a master's degree in astronomy at the University of Texas at Austin in 1983, he earned his master's (1989) and doctorate (1991) in astrophysics at Columbia University. For the next three years, he was a postdoctoral research associate at Princeton University, and in 1994, he joined the Hayden Planetarium as a staff scientist and the Princeton faculty as a visiting research scientist and lecturer. In 1996, he became director of the planetarium and oversaw its $210-million reconstruction project, which was completed in 2000.

On September 14th, 2015, a ripple in the fabric of space, created by the violent collision of two distant black holes over a billion years ago, washed across the Earth. As it did, two laser-based detectors, 50 years in the making – one in Louisiana and the other in Washington State – momentarily twitched, confirming a century-old prediction by Albert Einstein and marking the opening of a new era in astronomy. Join some of the very scientists responsible for this most anticipated discovery of our age and see how gravitational waves will be used to explore the universe like never before. This program will feature exclusive footage from director Les Guthman’s upcoming documentary chronicling the drama of the gravitational waves discovery.

Song: Metallica - Astronomy (Original by Blue Öyster Cult) Album: Garage Inc (1998) A great song proformed by Metallica. Never been played live before, but should be. As Requested, here are the Lyrics... Clock strikes twelve and moondrops burst Out at you from their hiding place Like acid and oil on a madman's face His reason tends to fly away Like lesser birds on the four winds Like silver scrapes in May And now the sand's become a crust Most of you have gone away Come Susie dear, let's take a walk Just out there upon the beach I know you'll soon be married And you'll want to know where winds come from Well it's never said at all On the map that Carrie reads Behind the clock back there you know At the Four Winds Bar Hey! Hey! Hey! Hey! Fou...
What is the biggest star in the Universe ✶ Astronomy Space Documentary 2016 Look up at the night sky and it is filled with stars. But only a microscopic fraction are visible to the naked eye. In fact, there are estimated to be 100 billion stars in 10,000 billion galaxies in the visible universe. This means that there are roughly 1024 stars out there. These spectacular powerhouses come in an array of different colours and sizes – and many make our own Sun look like a mere pipsqueak. But which is the true giant of the heavens? Well, we have to start by defining what we mean by giant? Is it the one with the largest radius, for example, or the greatest mass? ➤ Subcribe now: https://goo.gl/ECRZqM Thanks for watching!
All I know is that this falling star will die
For a moment light the sky and lead me home
I don't know why this task has been so hard
We've spent out time apart but not alone
This is what I have been given I hope that you can
I hope that you can understand there are reasons beyond ours
The creator holds the stars up in the sky
But you are by far bright and shining star in the sky tonight
This is what I have been given the hardest part is living
With leaving you alone
This is what I have been given the hardest part is living
With leaving you alone
Alone alone, we're not alone
Alone alone, we're not alone
Just like all the rest of them I can't bring you down
You're a million miles from here
But you are by far the brightest shining star in the sky tonight
This is what I have been given the hardest part is living
