Infrared observations of the Circinus Galaxy may help reveal the shape of the dusty region fueling its active galactic nucleus and shed light on what governs dust structures in other galaxies.
X-ray observations and cosmic coincidence unveil the details of a distant supermassive black hole. The result could be a first step in expanding our understanding of how black holes have beefed themselves up over the last several billion years.
A stellar-mass black hole in the iconic galaxy M83 seems to have kept eating long after it should have stopped. If true, the discovery could have implications for how much black holes can affect their environments.
Astronomers have found supermassive black holes in 151 dwarf galaxies, surprising expectations and providing a time machine into black hole formation.
Strange emission from a distant galaxy paints an enigmatic picture of what’s happening inside its core. One solution: instead of one supermassive black hole, the galaxy hosts two trapped in a tight dance around each other.
Astronomers have revealed a supposedly monster black hole to be rather ordinary in size.
Observations of one of the most powerful supernovas ever recorded suggest that the standard model for gamma-ray bursts might be missing a piece of the puzzle.
Observations reveal ionized metals in the jet shot out by a black hole, long-sought information that will help astronomers understand how these objects create their powerful beams.
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.
A pulsar discovered last April is helping astronomers measure the magnetic field surrounding our galaxy’s central black hole.
Astronomers around the world are watching as the gaseous object called G2 heads for a close pass around the Milky Way's central supermassive black hole. Now it looks like the distended cloud is starting to swing back toward us.
Twinkle, twinkle, quasi-star: cosmic lenses could tell us what you are.
Astronomers have been waiting for our galaxy’s slumbering supermassive black hole to stir for a snack. Instead, the universe handed them a different treat.
An exceptionally powerful gamma-ray burst on April 27th wowed astronomers around the world — and its fading was tracked by an alert backyard observer.
Astronomers have announced a new class of gamma-ray bursts, possibly created when some of the biggest stars in the universe go supernova.
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.
