Data collected using multiple NSF NOIRLab facilities reveal a gamma-ray burst that lasted more than seven hours and ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

CAPE CANAVERAL, Fla. (AP) — Scientists have discovered a gamma ray explosion outside our galaxy that’s not only exceptionally powerful, but also long-lasting. Telescopes on Earth and in space — ...

Gamma-rays are the highest energy (the shortest wavelength) type of electromagnetic radiation. They are classified as a type of an ionising radiation; with respect to alpha and beta particles they ...

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

When a distant galaxy briefly outshines everything around it in high-energy light, astronomers usually know which playbook to reach for. Gamma-ray bursts tend to fall into familiar categories, either ...

NASA observed GRB 250702B, a record-setting gamma-ray burst lasting days, likely caused by a black hole consuming a star, with data from multiple space and ground observatories.

A NASA-funded scientist has produced a new type of picture of the Earth from space, which complements the familiar image of our “blue marble”. This new picture is the first detailed image of our ...

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing ...

Researchers may have identified what could be a compelling clue in the ongoing hunt to prove the existence of dark matter. A mysterious diffuse glow of gamma rays near the center of the Milky Way has ...
