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.
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.
Fasten your seat belt and buckle your eyeballs -- 2015 should be a wild ride in space. We'll see Pluto up close for the first time EVER, zoom through the Kuiper Belt, and maybe even see black holes in detail. Ian O'Neill has his top space stories.
NASA's Nuclear Spectroscopic Telescope Array has turned its gaze from distant black holes and focused on our sun, producing the most sensitive measurement of high-energy solar X-rays ever achieved.
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.
