A team of astronomers including George Washington University physics Ph.D. student Eliza Neights recorded an extraordinary cosmic outburst this July which likely heralds a new kind of stellar ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...

When space telescopes blazed with high-energy radiation for hours earlier this year, astronomers suspected that they were witnessing something special. The cosmic flash GRB 250702B was no ...

A flash of high-energy light from deep space has forced astronomers to rethink what they thought they knew about the most violent explosions in the universe. The event, a strange gamma-ray burst that ...

A space explosion detected this summer burned for days on end, making it the longest and most unusual gamma-ray burst ever seen. Gamma-ray bursts are the universe’s most powerful explosions. They ...

Australia's SpIRIT nanosatellite is the first space telescope funded by the Australian Space Agency to carry a scientific instrument built by another nation's space agency. When you purchase through ...

You might think astronomers have seen it all, but the universe still throws us occasional new mysteries to keep us on our toes. They aren’t that unusual to spot—the universe is so big and GRBs are so ...
