Astronomers have discovered a supermassive black hole scarfing down gas just 690 million years after the Big Bang.
A team of astronomers has found signs of small stars forming within a few light-years of the Milky Way’s central black hole.
LIGO has detected another black hole merger, raising the tally to five.
Observations of a stellar explosion that refused to fade away have astronomers scratching their heads. What created the blast — and could it explain massive black holes?
Two telescopes — one on the ground and one in space — watched a black hole’s jet turn on, enabling astronomers to probe its origin.
Three American physicists have received the Nobel Prize in physics for their contributions to the discovery of gravitational waves.
A few decades ago, astronomers thought they had figured out how quasars operate. Now, a new study has thrown a wrench in the works.
Gas flows in the early universe may have kept clouds from collapsing too soon, enabling them to grow into massive black hole seeds.
Teaming up with LIGO, Europe’s Virgo detector has bagged its first gravitational waves. The three-observatory detection enabled scientists to better pinpoint the merging black holes’ location.
Astronomers have found what could be the closest known pair of supermassive black holes detected via direct imaging, orbiting each other only a light-year apart.
Astronomers monitoring a tight pair of supermassive black holes have observed their orbital motion.
A team of astronomers has taken a close look at a nearby galaxy — and discovered an unusual structure that sheds light on supermassive black holes’ relationships with their host galaxies.
Scientists with the gravitational-wave observatory announce another discovery, this time of a black hole merger twice as far away as previous detections.
Astronomers have discovered a supermassive black hole not sitting in its customary seat at the center of its galaxy. Gravitational waves from a recent merger may have ejected the black hole.
Astronomers have found newborn stars in gas pouring out of a galactic nucleus.
Winds that charge away from supermassive black holes at a fraction of the speed of light have long been mysterious and even contentious. Now, new evidence sheds light on their origins.
Astronomers have discovered long filaments of cold gas — the ingredient for making stars — cocooning giant bubbles inflated by a black hole.
An intermediate-mass black hole might be lurking within a dense stellar cluster — a discovery that could point toward how these oddities form.
Unlucky stars serve as brilliant but short-lived snacks when they wander too close to supermassive black holes. But one such black hole is still gnawing on its stellar meal after a decade.
Astronomers have discovered an object in the active galaxy Cygnus A that wasn’t there before.
Every now and then, the Milky Way’s central, supermassive black hole tears apart a star and flings away some of its innards. Now astronomers think they know how to spot these cosmic spitballs.
The Chandra X-ray Observatory has gazed at a small patch of sky for almost 12 weeks, revealing 1,008 X-ray-emitting sources — most of them supermassive black holes.
From the discovery of gravitational waves to the building evidence that a massive planet could exist beyond Pluto, it has been a thrilling year for astronomy research. We recap.
An incredible blaze of light discovered more than a year ago still has astronomers baffled as to its cause - and the answer may be contrary to recent headlines.
Astronomers have spotted a supermassive black hole in a stripped-down galaxy racing away from a near-fatal close encounter in the center of a galaxy cluster.
