Gravitational waves -- ripples in the fabric of spacetime -- aren’t just an Einstein theory any more. A team of international scientists announced Thursday that they confirmed the waves’ existence after recording feedback from a black hole collision a billion…
What’s making this galaxy shine with the light of 300 trillion suns?
In a galaxy far, far away -- specifically 12.5 billion years from Earth -- shines the light of over 300 trillion suns.
How seeing a black hole’s shadow will tell us if Einstein was right

Deadly altitudes, breathtaking skies, treacherous roads, wild donkeys -- it's all part of working on the most sophisticated telescope in the world.
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,”…
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…
