Astronomers might have glimpsed a supermassive black hole snacking on a brown dwarf in a galaxy 47 million light-years away.
Observations of Milky Way’s chaotic center show hints of stars forming just two light-years away from our galaxy’s supermassive black hole.
As we celebrate the golden anniversary of quasars' discovery, some astronomers are pausing to question the direction of the field.
An X-ray flare revealed a bizarre black hole binary system, where a mysterious, moving structure blocks its visible light.
X-ray observations of a distant supermassive black hole might end a decades-long debate over the nature of these X-ray signals. But not everyone’s convinced that the observations are what they appear to be.
Astronomers investigating a supernova remnant see nothing but swirls of gas. The lack of stellar remains means the explosion must have birthed a black hole only 1,000 years ago.
Scientists might be closer to detecting one prediction of Einstein's theory of gravity than they thought they were.
A record-breaking black hole lurking at the center of a compact galaxy weighs about 17 billion Suns, a new study finds. Now astronomers are wondering: how did such a small galaxy come to harbor a leviathan?
A simulation published in yesterday's Science shows how black holes govern their surroundings. Watch a black hole work its magic in this new video.
Our galaxy’s central supermassive black hole emits regular, mysterious X-ray flares. For the first time, NASA’s newest sharp-eyed telescope has captured a high-energy view of the action.
A new image from the Australia Telescope Compact Array shows a series of brilliant knots along the jet shooting from a supermassive black hole. While not the first sighting of a string of pearls gracing a galaxy's jet, the new image is a striking look at a mysterious phenomenon.
Astronomers announced that they've successfully tracked a star that takes less than 12 years to whip around the Milky Way's central black hole. The star isn't so special on its own, but combined with other observations it might help unwrap the region's mysteries.
New radio observations suggest that one of the brightest globular clusters in the sky, Messier 22, hosts two stellar mass black holes.
The Event Horizon Telescope team has unmasked the heart of the jet-shooting galaxy M87, paving the way for astronomers to discover how black holes create their superpowered streamers.
Astronomers have spotted an unusual "ultraluminous" burst of X-rays coming from the otherwise barren region between the grand spiral arms of Messier 83.
What would happen if I fed animatter into a black hole? Could this be a treatment to get rid of black holes? No. Antimatter has positive mass just like ordinary matter, so the black hole would merely get larger and heavier. Whatever fireworks happened inside the hole, if the anitmatter met up with ordinary...
A close pair of quasars in Pisces turns out just that, not the record-breaking gravitational lens that astronomers had hoped.
A team of astronomers announced on Monday compelling new evidence that black holes do exist in nature.
