When a quasar, a black hole-fueled beacons that shines from across the cosmos, went dark, astronomers set out to find out why.
Black holes may have a limit to how much they can eat in the public eye.
Gossip is racing around the physics and astronomy community: has LIGO finally heard its first black-hole merger? Here’s the reality.
Astronomers have detected magnetic fields writhing around the Milky Way's central black hole.
Astronomers have spotted what appears to be a regular signal coming from the blazar PG 1553+113.
X-ray observations suggest that flares happen when a black hole's "atmosphere" contracts and launches away from it.
The last hurrah of a star wrenched apart by a supermassive black hole tells astronomers what the stellar crumbs are doing.
The answer is a tantalizing maybe. Astronomers are investigating whether an increase in the number of flares from Sgr A* are due to the recent close passage of a dusty object known as G2.
Astronomers think a bright X-ray source in the galaxy NGC 1313 is a mid-size black hole.
Astronomers are investigating a new technique for finding close pairs of supermassive black holes, and they might have found one in the nearest quasar.
Astronomers have confirmed that the quasar PG 1302-102 is probably a binary supermassive black hole, its members less than a tenth of a light-year apart.
Astronomers have identified the smallest supermassive black hole ever detected in a galaxy’s center.
On June 15th a quiet black hole, V404 Cygni, suddenly flared for the first time since 1989.
The NuSTAR telescope has spied high-energy X-rays from five supermassive black holes shrouded in a thick veil of dust and gas, a test run that will lead to a better census of these hidden beasts.
A supermassive black hole in the early universe is at least 10 times too heavy for its host galaxy, raising questions about galaxy and black hole coevolution.
Combining a novel technique and a world-class telescope, astronomers have measured the mass of the supermassive black hole at the center of barred spiral NGC 1097.
Researchers using NASA’s Wide-Field Infrared Survey Explorer (WISE) have discovered the most luminous galaxy to date.
A team of astronomers has found indirect evidence of a supermassive black hole’s event horizon, providing further proof that these wacky objects actually exist in nature.
Scientists have found what seems to be an intermediate-mass black hole in a spiral galaxy 100 million light-years away. If its size is confirmed, it could provide much-needed insight into black hole evolution.
New observations suggest that several dozen low-mass stars, and eventually perhaps even planets, are forming just 2 light-years from our galaxy’s supermassive black hole.
Astronomers have discovered one of the brightest quasars in the early universe. The source, SDSS J010013.02+280225.8 (hereafter J0100+2802), is powered by a supermassive black hole at a redshift of 6.3, meaning that its light left it 12.8 billion years ago.
Astronomers poring through two decades of archival and survey observations have discovered what looks like a pair of supermassive black holes closing in for a merger.
Over the course of ten years, a once-brilliant quasar seems to have stopped gobbling down nearby gas.
Orphaned black hole or weird supernova? A mysterious source of radiation has left astronomers contemplating exotic explanations.
On the much anticipated opening weekend of Interstellar, senior contributing editor Bob Naeye reviews the movie's facts and foibles.
