As galaxies go, our Milky Way is pretty quiet. Active galaxies have cores that glow brightly, powered by supermassive black holes swallowing material, and often spit twin jets in opposite directions.

WASHINGTON — The first gamma-ray burst to be seen in high-resolution from NASA’s Fermi Gamma-ray Space Telescope is one for the record books. The blast had the greatest total energy, the fastest ...

On the morning of October 9, astronomers’ inboxes pinged with a relatively modest alert: NASA’s Swift Observatory had just detected a fresh burst of energy, assumed to be coming from somewhere within ...

Astronomers using the Hubble Space Telescope have spotted the afterglow of an enormous gamma-ray fireball from a merging pair of stars in a galaxy almost 4 billion light years away. The blasts come in ...

Using the James Webb Space Telescope (JWST), scientists have finally solved the mysterious origins of the "BOAT," possibly the biggest cosmic explosion since the Big Bang. By solving this cosmic ...
