In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy ...

Astronomers have detected a gamma-ray burst (GRB) like none other. GRB 250702B was longer than any ever observed and repeated ...

Binary star system supernova science just hit a milestone: a Stanford-led team using 16 years of NASA Fermi data confirmed ...

The Jellyfish Nebula, one of the best-studied supernova remnants in our galaxy, may have been hiding a sibling this whole ...

Cosmic rays are made primarily of protons with a few electrons sprinkled in, and they can reach energies even higher than ...

For decades, astrophysicists have been puzzling over a mystery hidden in plain view: Most supernovae come from the biggest ...

The star that formed the Jellyfish nebula may have had a partner star that exploded 100,000 years earlier, according to ...

For the first time ever, astronomers have found two sibling stars that each exploded as supernovas, gaining a new view of ...

Scientists now for the first time have discovered evidence of two such massive stars from a binary system that both ran out of fuel and exploded ‌violently within a relatively short time.

When massive stars die, they explode, leaving behind supernova remnants. Given how common binary star systems are — more than half the stars in our galaxy have a companion — it stands to reason that ...

Imagine if Star Wars' Tatooine twin suns went supernova. Scientists may have just found that in our universe.

The Milky Way’s farthest spiral arms have long been sketched more from motion than measurement. Now three violent explosions ...
