Black Holes

In 2018, one of the brightest X-ray lights in the sky went dark, and scientists still aren't sure why.

The universe may be filled with "mirror" particles — and these otherwise-undetectable particles could be shrinking the densest stars in the universe, turning them into black holes.

Not all black holes are perfectly sleek and simple, a new study suggests.

Bumblebee gravity could explain dark energy — if it's proven true.

Scientists have found the most distant quasar yet known — and it's home to a seriously supermassive black hole.

New research proposes that the first black holes came from clumps of gravitinos, exotic, hypothetical particles that managed to survive the first chaotic years of the Big Bang.

A massive jet launched from our galaxy's supermassive black hole may have destroyed any red giant stars that wandered into its path, a new study suggests.

The big galaxy at the core of the cluster Abell 2261 should harbor a supermassive black hole that weighs as much as 3 billion to 100 billion suns. But astronomers can't find it.

Here, we take a look at some of the most spectacular black hole findings of 2020.

Black holes shorn of event horizons could lurk throughout the universe.

Scientists can now catch gravitational waves better than ever before.

At the center of a black hole, matter is compressed down to an infinitely tiny point, and all conceptions of time and space completely break down.

A new test of Albert Einstein's theory of general relativity has proved the 20th Century physicist right again, this time using a supermassive black hole.

Six galaxies were trapped in orbit around a supermassive black hole during the early history of the universe, new observations reveal.

The magnetic fields are more than a thousand times stronger than the magnetic field used in MRI machines..

The Nobel Prize in physics has been awarded to three scientists for their work involving one of the cosmos's most mysterious, darkest, secrets — black holes.
