Physicists have started to treat a once-fringe idea with surprising seriousness: that our entire observable universe might be the interior of a black hole that formed in some larger cosmos. The notion ...

A new image of M87 shows and confirms for the first time the feeding ring and jet of its supermassive black hole.

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 found three supermassive black holes on a collision course in a rare cosmic event, situated nearly 1.2 ...

For roughly half a century, astrophysicists have treated the behavior of matter around supermassive black holes as a solved ...

In a patch of sky about 1. 2 billion light-years from Earth, astronomers have found a cosmic rarity: three galaxies caught in ...

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the satellites we use for navigation, communication and Earth observation every ...

In this instance, two enormous black holes – 100 and 140 times the mass of Earth's sun – collided. The result? A black hole the size of a whopping 240 suns. Black holes this massive shouldn't be ...

A UK-based research project, TomoGrav, will produce the first 3D movies of black holes, mapping plasma flows and gravity in real time using advanced AI and global telescope networks.

In any other year, the supermassive black hole mentioned above would probably scoop the award for most striking outburst, but not in 2025. This year, that accolade goes to a flare designated ...

The highest energy neutrino ever detected from space may finally have an origin story. Mathematical analyses suggest that the ghost particle could’ve come from a theoretical object known as a ...

A supermassive black hole that’s 10 million times the mass of the Sun is hurtling through space, leaving a trail of gas ...
