Event Horizon Telescope data support the idea that magnetic fields control how black holes feed and grow.
This week in astronomy news, astronomers found planet-eating white dwarfs, a cluster of black holes, and a "farfarout" object that's now the most distant known in the solar system.
In the news this week: Globular clusters have the detailed scoop on our galaxy's past, and a "heartbeat" black hole binary in the Milky Way has gone mysteriously dim.
Astronomers have spotted a surprising number of quasars with jets launched within a couple of decades.
This year’s award goes to three researchers who played key roles in developing the theoretical and observational evidence for black holes.
Calculations suggest how black holes have amassed mass and predict what the black holes’ spins should be if this picture is correct.
Detailed calculations reveal a surprise about how black holes bend light around themselves, opening a new possibility for future observations.
Two studies support the suspicion that our galaxy’s black hole had one or more outbursts a few million years ago.
The sky's been bursting with exploding stars this season. Plus there's a new storm on Saturn. What's a skywatcher to do? Haul out the scope!
