Astronomers have cataloged over 500 gamma-ray bursts, which are some of the most violent explosions in the cosmos.

Scientists have found nuclear weapons could actually help deflect an incoming cosmic impact — not by blowing an asteroid up, ...

Astronomers have spotted an absolutely colossal cosmic chimney that stretches as far as 140 Milky Ways lined up side by side. These jumbo jets are being blasted from a supermassive black hole.

Nuclear devices generate massive amounts of X-rays. A new experiment suggests that might be enough to divert a killer ...

In a groundbreaking astronomical discovery, NASA’s Chandra X-ray Observatory and the Hubble Space Telescope have identified a ...

We now know that black holes occur frequently throughout the universe. One Sagittarius A* sits at the center of our galaxy, ...

This is the closest pair detected in the local universe using multiwavelength (visible and X-ray light) observations.

The concept was tested using Sandia's Z Machine, the most powerful X-ray source on Earth. By generating a burst of X-rays similar to those from a nuclear explosion, researchers were able to simulate ...

The first results from JAXA's XRISM X-ray telescope are out, and they reveal new features of the superheated gas around a ...

Extreme conditions prevail inside stars and planets. The pressure reaches millions of bars, and it can be several million degrees hot. Sophisticated methods make it possible to create such states of ...

In a groundbreaking discovery, astronomers have identified two pairs of supermassive black holes on the brink of merging, an event never observed before in the cosmos. NASA’s Chandra X-ray Observatory ...

It’s the start of the new Absolute line of reimagined DC heroes. It brings writer Scott Snyder back to the character that ...
