Galaxy Survives Black Hole’s Feast – For Now
The hungriest of black holes are thought to gobble up so much surrounding material they put an end to the life of their host galaxy by creating an energetic object called a quasar. Now, researchers found a galaxy that is surviving the black hole’s ravenous forces, continuing to birth about 100 Sun-sized stars a year.
Black Hole's Dust Ring May Be Casting Shadows From Heart of a Galaxy
Astronomers studying nearby galaxy IC 5063 are tantalized by a similar effect in images taken by NASA's Hubble Space Telescope. In this case, a collection of narrow bright rays and dark shadows is seen beaming out of the blazingly bright center of the active galaxy.
Echo Mapping in a Black Hole Accretion Disk and Torus (Animation)
Matter swirling around supermassive black holes creates bursts of light that "echo" in nearby dust clouds. These traveling signals could serve as a new cosmic yardstick.
Milky Way's Black Hole's Flash Illuminated Gas Far Outside Our Galaxy
About 3.5 million years ago, the supermassive black hole at the center of our Milky Way galaxy unleashed an enormous burst of energy. Now, eons later, astronomers are using NASA's Hubble Space Telescope's unique capabilities to uncover even more clues about this cataclysmic explosion.
Found: Three Black Holes On Collision Course
Astronomers have spotted three giant black holes within a titanic collision of three galaxies. Several observatories, including the Chandra X-ray Observatory and other NASA space telescopes, captured the unusual system.
