Astronomers have re-examined the biggest explosion ever seen, possibly the most massive explosion since the Big Bang, to ...

After NASA’s Fermi Gamma-ray Space Telescope and Swift Observatory spotted the BOAT, , an international team of astronomers ...

Space is filled with deadly forces, supernovae, gamma ray bursts, and asteroid impacts that can wipe out life in an instant.

The international CTAO LST Collaboration has released remarkable findings from observations of GRB 221009A—the brightest ...

Astronomers have determined what caused the brightest cosmic explosion ever recorded. Lasting a matter of minutes, the gamma-ray burst, named GRB 221009A, was observed by astronomers in October ...

A University of Colorado Denver engineer is on the cusp of giving scientists a new tool that can help them turn sci-fi into ...

The brightest gamma-ray burst ever seen may have been powered by a unique jet structure, scientists say. The discovery could shed new light on the origins of the universe.

The gamma-ray burst was so powerful that it showed up in the scientific data of spacecraft that aren’t even equipped with gamma-ray detectors, including orbiters at Mars and Voyager 1.

ESA’s International Gamma-Ray Astrophysics Laboratory, INTEGRAL, will be the most sensitive gamma-ray observatory ever launched, able to detect radiation from the most distant violent events.

As these beams sweep across the Earth, the highly sensitive Fermi gamma-ray telescope can observe their periodic pulses of energy. With more than 15 years of data, Fermi has transformed the field ...

As far as he knows, there’s not another Gamma Ray Bar in the country. “That’s a cool word,” he thought to himself while reading about the discovery of large gamma rays in outer space.
