Recent James Webb Space Telescope data confirms a decade-old theory that the universe's earliest supermassive black holes ...

As gas falls toward a black hole, it heats up and shines. If the glow becomes intense enough, it can push incoming gas away. Astronomers call this balancing point the Eddington limit, and for decades ...

Astronomers have discovered powerful magnetic fields steering gas, dust, and star formation in a dramatic galaxy merger.
