SUNSET: 
Black Hole Caught Spinning?
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.
Baby Black Hole Discovered
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.
Spacetime Ripples on the Horizon?
Scientists might be closer to detecting one prediction of Einstein's theory of gravity than they thought they were.
A Big Black Hole in a Small Galactic Pond
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?
Tilt a Black Hole and Watch What Happens
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.
The Flares from Milky Way’s Black Hole
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.
Beads on a Galaxy-Scale String
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.
Star Zips around Black Hole
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.
Astronomers Approach Black Hole
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.
X-ray Outburst in Spiral Galaxy M83
Astronomers have spotted an unusual "ultraluminous" burst of X-rays coming from the otherwise barren region between the grand spiral arms of Messier 83.
Black Hole Eats Stripped Star
A closely-watched flare from a gargantuan black hole in a distant galaxy has revealed to astronomers not only the mass of the black hole that ate the snack but the type of star that met its end as the meal.
Black Hole Breakfast En Route
Astronomers have discovered a dusty, stretched-out cloud heading for the supermassive black hole lurking in the Milky Way's core. The blob could be the meal the beast needs to wake up for a bit from its slumber, if the cloud survives its incoming trip on the dining cart.
Binary Quasar Is No Illusion
A close pair of quasars in Pisces turns out just that, not the record-breaking gravitational lens that astronomers had hoped.
More Evidence that Black Holes Are For Real
A team of astronomers announced on Monday compelling new evidence that black holes do exist in nature.
