The catalog of gravitational waves "heard" by LIGO, KAGRA and Virgo has doubled with detections of spacetime ripples.

In 2023, an incredibly high-energy neutrino struck Earth, challenging all conventional explanations. The origin of such a fast particle, whose energy far exceeds that generated by the most ...

Black holes are the most extreme objects in our universe - but could one actually destroy Earth? In this video, we explore the mind-bending science of black holes, from spaghettification to time ...

University of Oregon astronomer Yvette Cendes made a surprising discovery years after a black hole shredded a star. What is ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

APM 08279-5255 is a massive black hole (quasar) that contains about 140 trillion times the amount in all of Earth’s oceans ...

Astronomers have discovered the closest black hole to Earth. It's so close that its sister stars can be seen with the naked eye. Wednesday's announcement backs up the theory that there are lots of ...

When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves ...

The black hole would have to be within 25 light years from Earth, and we haven’t seen one that close yet. That’s not stopping Cosimo Bambi.

A subtle gravitational-wave “hum” from merging black holes may help settle the cosmic fight over how fast the universe is ...

Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space. The so-called "sleeping giant," named Gaia BH3, has a mass that ...
