Instead they circled a pulsar, the dead remains of an exploded star. Clearly nature excels at making planets, even under ...

In their study, the astronomers found that a supermassive black hole’s outer disk and torus could foster this cumulative ...

Webb observations of QSO1 suggest a giant black hole may have formed before its galaxy, challenging long-held theories of ...

After the Big Bang, particles formed, which gradually coalesced to form clumps of matter that further collapsed under gravity to spawn the first stars. Then the stars created galaxies. Some of those ...

Scientists have discovered that the universe's most massive black holes may form in the densest of stellar environments, or so-called globular clusters. It is in these clusters where violent ...

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

The most massive black holes in the universe detected by the ripples they make in spacetime were not born directly from collapsing stars, according to a new study. These cosmic giants instead build up ...

An artist's concept of a tidal disruption event (TDE), which happens when a star passes close to a supermassive black hole. The gravity of the black hole pulls material from the star and launches a ...

An illustration of a star that collapsed, forming a black hole. The black hole is at the center, unseen. Surrounding it is a dust shell moving away from the black hole and gas being pulled toward it. ...

In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes ...
