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.
Astronomers have developed a new method to measure distances to bright but faraway galaxies, a tool which will help better constrain the expansion rate of the universe.
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.
