Astronomers have detected a black hole embedded in the spiral arm of a galaxy 100 million light-years from Earth — but this isn’t any old black hole, it belongs to an extremely elusive class that may be the ‘missing link’ in black hole evolution.
Astronomers have discovered an out-of-place supermassive black hole -- 12 billion times more massive than the sun -- that inexplicably formed when the universe was less than 900 million years old.
It has long been assumed that the size of a supermassive black hole in a galaxy's core is intimately related to the number of stars that galaxy contains -- but it might not be that simple.
Astronomers studying an otherwise 'boring' galaxy over a billion light-years from Earth have been surprised to see a powerful storm erupt from its core.
For the first time, astronomers have observed the rapid dimming of a distant quasar and realized that the active black hole engine must have gone on an extreme diet.
The giant black hole at the center of the Milky Way galaxy recently spit out the largest X-ray flare ever seen in that region.
For the first time, physicists may have traced the source of the highest energy neutrinos -- sub-atomic particles with no electrical charge that race through the universe -- to the black hole at the center of the Milky Way.
Astronomers were excited for a massive cloud of gas to fall into the black hole at the center of our galaxy, but it survived to tell the tale. What happened? Continue reading →
