Tucked away in a small galaxy that whips around the Milky Way, there shines an especially bright remnant of a supernova. The quest to learn more about how the universe works often yields stunning and ...

Gamma-ray bursts are the most powerful explosions ever detected in the Universe. They are also one of the greatest mysteries of modern astronomy, since so far no clear evidence has existed to prove ...

Astronomers have discovered the shortest-ever gamma-ray burst (GRB) caused by the implosion of a massive star. Using the international Gemini Observatory, a Program of NSF’s NOIRLab, astronomers ...

On Oct. 9, 2022, the orbiting Swift and Fermi gamma-ray detectors observed the brightest gamma-ray burst (GRB) ever seen: GRB 221009A. Astronomers around the world quickly responded by turning as many ...
