The Black Hole Shadow in M87: One Year Later

The Event Horizon Telescope collaboration has released the image from its second major campaign, confirming the existence of a persistent black hole shadow and a potentially turbulent environment.

Black Holes in Early Universe Are Too Big

JWST observations of the universe as it was 12 to 13 billion years ago indicate that the black holes at the centers of small, early galaxies were more massive than expected.

Black Hole Rain

The planned LISA gravitational-wave detector might discover a shower of hundreds of small black holes falling in galactic centers.

Black Hole May Have Formed by Direct Collapse

Astronomers may have spotted a supermassive black hole in the early universe that formed when a gargantuan gas cloud imploded.

First Image of Black Hole Shadow and Jet Together

For the first time, astronomers have seen how the big plasma jet shot out by a supermassive black hole connects to the material falling into the black hole.

The Challenge of Weird Black Hole Mergers

When spacetime shivers last only a fraction of a second — as in the case of the massive-black-hole merger GW190521 — astronomers struggle to uncover their origins.

Hotspot Zooms Around Our Galaxy’s Black Hole

Astronomers have detected a bubble of hot gas circling our galaxy’s central black hole soon after seeing a flare, suggesting both arose from the same process.
