A glowing molecular cloud shines today because of a 200-year-old flare let out by our galaxy’s supermassive black hole, scientists say.
The supermassive black hole at the center of the Milky Way released an unusual number of strong flares in 2019. Now, astronomers are trying to figure out why.
This year’s award goes to three researchers who played key roles in developing the theoretical and observational evidence for black holes.
Two studies support the suspicion that our galaxy’s black hole had one or more outbursts a few million years ago.
Every now and then, the Milky Way’s central, supermassive black hole tears apart a star and flings away some of its innards. Now astronomers think they know how to spot these cosmic spitballs.
The Milky Way's central supermassive black hole eats only a fraction of the gas available to it. New X-ray observations suggest how the beast manages to stay so trim when faced with a feast.
