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 ...

In a remote sector of deep space, researchers have identified something unexpected — a signature that hints at molecular ...

Scientists are developing new methods to turn black hole images into time-resolved 3D movies, revealing how plasma, jets, and gravity behave near event horizons ...

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

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

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 ...

Three merging galaxies host three active black holes, offering rare insight into galaxy and black hole growth.

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 ...

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 ...

Astronomers have confirmed the first known triple system in which all three galaxies host actively feeding, radio-bright ...
