An astronomer and ‘black hole historian’ explains how the parts of the universe black holes grow in might influence how quickly they become bright, supermassive objects.
By timing radio pulses from an array of galactic pulsars, scientists see hints of gravitational waves from supermassive black hole pairs in a breakthrough that may reveal hidden details of galaxy evolution.
Sagittarius A* is a massive black hole at the center of the Milky Way. Now that astronomers have imaged it, they can begin to learn more about black holes within other galaxies across the universe.
Despite the name, some black holes effectively “shine” as they suck up nearby material with such force that it begins to glow. New research reveals a new method for detecting these active black holes.
Astronomers have taken a close-up look at the jets of plasma streaking away from a supermassive black hole - one of the strangest and most energetic features of galaxies.
Some of the baby radio galaxies found may not be ‘babies’ at all. Rather, they may be ‘angsty teens’, rapidly growing into adults much faster than researchers had anticipated.
If you are a sci-fi junkie you’ve probably wondered what would happen if you were unlucky enough to fall into a black hole. How well you’d fare all depends on the type of black hole.
Roger Penrose helped resurrect Einstein’s general theory of relativity, and Reinhard Genzel and Andrea Ghez showed there was a black hole in the middle of our galaxy.

There is a massive black hole in the center of the Milky Way galaxy. Measurements of star orbits near this black hole suggest that there may be a second companion black hole nearby.
