Black holes like the one shown in this illustration can grow astonishingly massive by feeding on immense amounts of matter. But just how big can they get? In the early 1960s astronomers discovered a ...

Researchers believe the 'ultramassive' black hole is big enough to be the largest of its kind ever detected. Black holes are regions of space where the pull of gravity is so intense that even light ...

Scientists using the James Webb Space Telescope (JWST) have discovered the oldest known black hole in the universe. Nestled within a glowing red galaxy, it dates back 13 billion years and provides a ...

"This is amongst the top 10 most massive black holes ever discovered, and quite possibly the most massive." About 5 billion light-years away from where you're sitting, in one of the most massive ...

A gargantuan black hole hiding in a galaxy 5 billion light years away is the most massive that has been directly measured, more than 10,000 times as massive as the supermassive black hole at the ...

Astronomers have discovered what could be the largest black hole ever detected. With a mass of 36 billion times that of our Sun, its gravity is so powerful that it bends the light of an entire galaxy ...

Scientists have discovered a giant black hole that they believe may have been formed in the first few microseconds after the Big Bang. The black hole is so huge that it may change our understanding of ...

Astronomers have discovered the oldest and most distant black hole — a behemoth that likely formed at the dawn of the universe, more than 13 billion years ago. The black hole lies at the center of a ...

"The biggest surprise of all was that the black hole was not located inside either of the two nuclei but in the middle. We asked ourselves: How can we make sense of this?" Using the James Webb Space ...

In an astounding development that has stirred the global scientific community, a black hole has been discovered growing at a rate that exceeds the limits set by our current models. This surprising ...

One of the most notable aspects about our planet—if observed from the outside—is that it spins. Earth’s spin defines our days, setting the fundamental rhythm of life on our world. The moon spins, too.

Talk about epic. A collision of two black holes is so extreme that it’s challenging physics theories of how large black holes form and merge. The two black holes had masses bigger than any before ...
