GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...

A team of astronomers led by Matteo Cerruti of Paris Cité University reports multi-wavelength evidence for a repeating, roughly 3-year modulation in the gamma-ray output of the blazar S5 1044+71, a ...

Add Yahoo as a preferred source to see more of our stories on Google. The orange dot at the center of this image represents a powerful explosion that repeated several times over one day. - A. Levan, A ...

The longest gamma-ray burst ever recorded did not behave like a quick cosmic flash. Instead, it burned across the sky for more than seven hours, forcing astronomers to rethink what powers the universe ...

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 ...

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 ...

NASA sent a retired Cold War spy plane on a storm-chasing mission, and it discovered that big thunderstorms are very radioactive. Large thunderstorms produce so much gamma radiation that the clouds ...

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 ...
