Scientists traced a mysterious surge of low-energy gamma rays from zinc-70 to magnetic changes occurring inside its nucleus.
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 ...
In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy, unstable atomic nuclei. Mapping the gamma-ray emissions of so many ...
The LHAASO observatory has detected gamma rays above 100 TeV from a gamma-ray binary for the first time, challenging current models of cosmic particle acceleration. (Nanowerk News) The Large High ...
The Jellyfish Nebula, one of the best-studied supernova remnants in our galaxy, may have been hiding a sibling this whole time.
