As galaxies mature, they stop forming stars -- but why? Now astronomers are hot on the trail of finding the culprit. Continue reading →
A black hole is eating a star faster than scientists had thought was possible, and it's unleashing unusually bright X-ray signals that may help scientists understand a group of weird, superbright objects in deep space.
Are you ready to get "spaghettified"? Julian has the gooey, stretchy, bizarro physics behind a human's leap into a supermassive black hole.
A surprisingly massive black hole has been discovered in the core of a small, compact galaxy -- a finding that appears to be a weird cosmic contradiction.
A recent discovery of an intermediate-mass black hole in a nearby galaxy offers the best evidence yet that a class of medium-size black holes exists.
Astrophysicists have analyzed two decades-worth of X-ray data and discovered three events inside galactic cores that can be interpreted in only one way: stellar destruction. Continue reading →
As part of an ongoing survey of active galaxies, the Hubble Space Telescope looked deep into the heart of one stunning example just 32 million light-years from the Milky Way. Continue reading →
For the first time, three supermassive black holes have been discovered in a tight orbital dance inside the center of a galaxy 4 billion light-years away. Continue reading →
