What to know about Astrophysics and Cosmology

Researchers using the James Webb Space Telescope have measured the mass of a supermassive black hole in the early universe known as QSO1. The findings suggest that some supermassive black holes may have formed before their host galaxies, potentially supporting theories of primordial or direct-collapse black holes.

What happened

Webb reveals black hole that formed before its galaxy Sadie Harley Scientific Editor Robert Egan Associate Editor Which comes first, the galaxy or the black hole?

Why it matters

We don't know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can gobble up surrounding material and merge over time to form more massive entities.

Common ground

But it's hard to figure out how black holes millions to billions of times the mass of the sun, thousands of which have now been detected in the early universe, could have grown so quickly from such small seeds.
