Two massive black holes just collided in deep space, forming a single cosmic monster 225 times the mass of our Sun. This is the largest black hole merger ever recorded by gravitational wave detectors — and it’s blowing scientists’ minds.

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.

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.

Scientists have made a terrifying discovery: two black holes are on a collision course, set to merge into a massive hole that’s more than 225 times the size of the sun. If that isn’t scary enough, experts say the two black holes merging together are also spinning rapidly,
