supermassive black hole

When the supermassive black hole at the center of the Milky Way consumes an incoming cloud of gas, NASA’s Swift telescope will be on the scene.

The incredible luminosity of a black-hole system known as ULX-1 may force a rethink of the leading theories that explain how some black holes radiate energy, researchers said.

An extremely powerful radio telescope in Chile peered deeply into the universe and captured an incredible sight: an ancient black hole chowing down on a massive snack.

Using a powerful X-ray telescope, astronomers won a round of hide-and-seek with 10 supermassive black holes.

The Milky Way's giant black hole turns out to be a messy eater. Of all the gas that falls toward it, 99 percent gets spewed back out into space, new observations show.
