Correct: You'd die. But aside from that, what would happen if a black hole the size of a nickel suddenly appeared on Earth? A new video explains.
Researchers at the European Space Agency harness the natural lensing properties of cosmic gravity to get a closer look at a black hole.
A black hole that hasn't been heard of since 1989 has suddenly become active again and is now the brightest object in the X-ray sky.
Astronomers have pieced together Hubble data to observe a collision between knots of matter in the jet of a supermassive black hole for the first time.
It takes a mighty wind to keep stars from forming. Researchers have found one in a galaxy far, far away -- and NASA made a short movie about it.
Scientists have found a black hole 12 billion times more massive than the Sun that was formed so soon after the Big Bang it's challenging what we know about black holes.
A winner has been declared in the debate about stars, dark matter and black holes, and it can help us understand how elliptical galaxies grow.
Astronomers have spotted in an otherwise not-very-interesting galaxy a raging storm erupting from the black hole at its core.
If the two black holes meet, they could release as much energy as 100 million supernova explosions as they shatter their galaxy, a new study finds.
Its root cause still undetermined, a huge X-ray flare from the Milky Way's center has made NASA scientists sit up and take notice.
