Discoveries keep pouring out of the James Webb Space Telescope (JWST). Researchers observed an unusual cluster, which they dubbed the Infinity Galaxy. It appears to support a leading theory on how some supermassive black holes form.

Yale astronomer Pieter van Dokkum and a team of researchers have discovered an object in space they call the "Infinity" galaxy—two recently-collided galaxies that, together, look like the symbol for infinity.

But in the past two decades, new types of black holes have been seen and astronomers are beginning to understand how they form. Called supermassive black holes, they have been found at the center of pretty much every galaxy and are a hundred thousand to a billion times the mass of our sun.

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have instead formed inside a colossal black hole.

It turns out there is a way to make a coloured black hole—as long as by colour you mean quantum chromodynamic charge. PBS Space Time is available to stream on pbs.org and the free PBS App ...

Some scientists think black holes are back doors to other universes. If true, this theory could explain how all of the matter in our universe was created.

By using protons to probe how a magnetic field responds to an expanding plasma, experimenters have replicated the particle jets spewed out by active black holes.

The first hint of a rogue black hole came when it passed in front of a dim background star in 2011. Black holes have so much gravity that they visibly warp the space around them.

This artist’s illustration depicts a dwarf galaxy that hosts an active galactic nucleus — an actively feeding black hole. In the background are many other dwarf galaxies hosting active black ...
