A Black Hole’s Puzzling X-Ray Bursts

In 2019, a supermassive black hole in a galaxy 300 million light-years away woke up. Now, it’s puzzling astronomers with an unexpected slowdown in its X-ray bursts.

Astronomers Discover Second Failed Supernova Candidate

Astronomers might have spotted a star in the Andromeda Galaxy collapsing directly into a black hole, without the accompanying fanfare of a supernova.

Not Every Galaxy Has a Central Black Hole

Many less massive galaxies appear to lack something astronomers thought was ubiquitous: a central, supermassive black hole.

Boosting the Gravitational Wave Background

Why is the gravitational-wave background — the hum made by supermassive black holes colliding across the universe — stronger than expected?

Red Giant “Star Songs” Reveal Their Chaotic, Pasts

Astronomers have tuned in to the celestial “songs” of two red giant stars to reveal their hidden histories — including a case of stellar cannibalism.

Early Galaxy Hosts Black Hole with the Mass of 50 Million Suns

Astronomers using the James Webb Space Telescope have confirmed that, just 800 million years after the Big Bang, there is a galaxy that contains a supermassive black hole — and not much else.

New Black Hole Merger Breaks Record

Gravitational-wave astronomers have detected the collision of two beefy black holes, which created the most massive merger-made black hole found thus far.

A bright disc of purplish, white and gold lines surrounds a black ellipse-shaped area, that looks like a hole in space. A ball of shining material pierces through the disc; an eruption of bright white-to-gold rays encircles the small hole in the disc provoked by the passage of the shining ball.
