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.
The gaseous object G2 has survived its swing around the Milky Way’s central supermassive black hole, but the questions of what it is and where it comes from remain unanswered.
Two new studies suggest that ultraluminous X-ray sources are not all created by beefy black holes.
Astronomers have detected a supermassive black hole in the center of a tiny galaxy — where it has no right to be.
A new diagram might link the diverse visible-light characteristics of quasars to two physical properties — essentially, their accretion rate and orientation. If the analysis holds up, it could point the way toward a long-sought unification.
A new measurement could be the farthest back in time astronomers have ever reached when measuring a black hole’s spin.
New data shed light on last month’s exciting discovery of a black hole triplet — but they suggest instead that the threesome is really just a twosome.
Astronomers have detected a high-speed, long-lasting gas streamer spewing from the active galactic nucleus of NGC 5548. This discovery might provide new insights into how supermassive black holes influence their host galaxies.
Astronomers have discovered that one member of a pair of supermassive black holes is actually a pair itself, turning the system into the most distant black hole triplet yet detected and raising hopes for future discoveries.
Newly published observations provide the first real evidence supporting a theory that tells us how black hole jets form.
Galaxies’ central black holes are surprisingly simple creatures at heart, but they have a complicated past. New studies are starting to remove history’s obfuscating veil.
A bizarre X-ray flare first spotted in 2010 could be a signal from two black holes that will ultimately unite into a single beast.
