The astronomers estimated that the "ultramassive" black hole is over 10,000 times the mass of the Milky Way's black hole.

Astronomers have identified an ultramassive black hole that could be the largest ever measured, hidden in a distant galaxy ...

One possibility is that the background waves come from defects in the very early universe as it changed phases. The idea is that this left an imprint in space-time, like the cracks that form when ...

Astronomers have identified a 36-billion-solar-mass black hole in the distant Cosmic Horseshoe galaxy, using a new technique ...

Two fresh ideas are giving scientists new ways to think about how the universe’s hidden mass came to be. Together, they paint ...

Astronomers are trying to listen to the universe's background hum — a cascade of gravitational waves believed to exist since the first rapid inflation of space following the Big Bang over 13.8 ...

The detection of a predicted universal background of gravitational waves rippling across the fabric of space-time was announced last Wednesday by the NANOGrav consortium of over 190 scientists at ...

“We have evidence of what we call ‘the gravitational wave background,’ which is a hum of gravitational waves coming from all of the gravitational waves in the universe,” Dr. Sarah Vigeland ...

Astronomers across the world announced on Thursday that they have found the first evidence of a long-theorised form of gravitational waves that create a "background hum" rumbling throughout the ...

It was that same signal-based approach that we found can be applied to cancer research. A potential new approach to ...

It's difficult to know how many stars have gone supernova since the Big Bang 13.8 billion years ago, but it's just possible that studying the background "buzz" of neutrinos, the so-called diffuse ...
