First Black Holes Maybe Had Supersonic Help

Gas flows in the early universe may have kept clouds from collapsing too soon, enabling them to grow into massive black hole seeds.



Fourth Gravitational Wave Event Detected

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.

Swift Black Hole Winds May Shape Galaxy

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.

Active Black Hole Encourages Starbirth

Astronomers have discovered long filaments of cold gas — the ingredient for making stars — cocooning giant bubbles inflated by a black hole.

Best Evidence Yet for an Intermediate-Mass 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.

Black Hole Feeds on Star for a Decade

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.

Milky Way’s Black Hole Is Throwing Cosmic Spitballs

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.
