At their closest, Mars and Regulus sit just 0.7 degrees apart. That’s about a little finger’s width at arm’s length. It's one of the year's tightest planetary conjunctions.

Supermassive black holes usually lurk unseen, but when an unlucky star drifts too close they ignite titanic outbursts ...

Each of the supermassive black holes the researchers described lies at the center of a distant galaxy. And each were observed to have suddenly brightened for several months after shredding up a ...

The image of supermassive black hole Sagittarius A * was created using data from the Event Horizon Telescope Collaboration.

It’s the largest black hole jet we’ve discovered to date. What makes this particular jet so exciting for astronomers is not only its size. It’s also estimated to be 1.2 billion years old.

Black holes are invisible, yet they are among the brightest things in the universe. If a star wanders too close to a black hole, it gets torn apart in a fireworks show called a tidal disruption ...

Astronomers used AI and high-throughput computing to analyse Event Horizon Telescope data on black holes. Sagittarius A* is spinning near top speed with its rotation axis pointing towards Earth ...

For years, scientists have theorized that some black holes could actually be wormholes, and a new study shows that this space-time mimicry could in fact be possible.

Each of the supermassive black holes the researchers described lies at the center of a distant galaxy. And each were observed to have suddenly brightened for several months after shredding up a ...

A neutron star's final moments may spark violent starquakes, monster shock waves, and even a fleeting, never-before-seen object called a black hole pulsar.

A team of astronomers led by Michael Janssen (Radboud University, The Netherlands) has trained a neural network with millions of synthetic black hole data sets. Based on the network and data from ...
