In a galaxy far, far away — specifically 12.5 billion years from Earth — shines the light of over 300 trillion suns.
Even though black holes are vital to our understanding of the universe, no one has ever seen one — yet. To change this, a team of scientists in northern Chile, is using a network of telescopes around the globe to capture an image of a black hole for the first time to prove Einstein’s Theory of General Relativity. Rebecca Jacobson reports. Continue reading
Black holes are some of the most exotic objects in our universe. But how do you see something that, by definition, you can’t see? The answer will take a telescope the size of the Earth. Continue reading
Deadly altitudes, breathtaking skies, treacherous roads, wild donkeys — it’s all part of working on the most sophisticated telescope in the world. Continue reading
Astronomers have discovered a cluster of several thousand stars that was ejected out of a distant galaxy at a stellar speed of more than two million miles per hour. The group of “runaway stars,” named HVGC-1 for “hypervelocity globular cluster,” was found by Nelson Caldwell and his team at the Harvard-Smithsonian Center for Astrophysics after they found the bright sphere traveling at a high velocity from the the elliptical galaxy Messier 87.

Last week, Stephen Hawking declared “there are no black holes.” What exactly that means has physicists scratching their heads. The problem is 40 years of paradoxes as scientists try to understand how black holes seem to break two rules of physics. Continue reading
NASA announced Tuesday that it would send a final repair mission to the Hubble Space Telescope, tentatively in 2008, to extend the life of the orbiting observatory to at least 2013. Hubble’s senior project scientist discusses the history and future of the telescope. Continue reading
