The NuSTAR telescope has spied high-energy X-rays from five supermassive black holes shrouded in a thick veil of dust and gas, a test run that will lead to a better census of these hidden beasts.
A team of astronomers has taken a close look at a nearby galaxy — and discovered an unusual structure that sheds light on supermassive black holes’ relationships with their host galaxies.
Astronomers have spotted a supermassive black hole in a stripped-down galaxy racing away from a near-fatal close encounter in the center of a galaxy cluster.
Black holes may have a limit to how much they can eat in the public eye.
Astronomers have detected a supermassive black hole in the center of a tiny galaxy — where it has no right to be.
Astronomers have found what could be the closest known pair of supermassive black holes detected via direct imaging, orbiting each other only a light-year apart.
Astronomers monitoring a tight pair of supermassive black holes have observed their orbital motion.
Winds that charge away from supermassive black holes at a fraction of the speed of light have long been mysterious and even contentious. Now, new evidence sheds light on their origins.
Astronomers have identified the smallest supermassive black hole ever detected in a galaxy’s center.
When a quasar, a black hole-fueled beacons that shines from across the cosmos, went dark, astronomers set out to find out why.
