Astronomers at the University of Hawaii uncovered black hole events so packed with energy, they were the biggest explosions seen since the Big Bang.

Physicists have not yet watched a black hole literally blow itself apart, but they are closing in on the conditions where such an event might finally be seen. At the same time, telescopes are catching ...

Scientists may have to rethink their playbook for studying gamma-ray bursts, the most powerful known cosmic explosions, after a blast detected in July set a new record by firing energetic jets for ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe ...
