NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA ...

Fermi’s sensitivity and resolution allowed the researchers to filter out other gamma-ray sources like rapidly spinning stellar remnants called pulsars, background radiation, and Westerlund 1 itself.

The Fermi Bubbles are two enormous lobes of gamma‐ray emission extending roughly 8–10 kiloparsecs above and below the Milky Way’s centre. First revealed by the Fermi Gamma‐ray Space Telescope, these ...

NASA’s Fermi telescope has detected what may be the first confirmed gamma-ray signal from a superluminous supernova — one of the most extreme explosions in the universe. Scientists believe the blast ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

At 8:56 AM ET on Tuesday, NASA's Fermi Gamma-ray Space Telescope automatically detected a new long-duration gamma-ray burst, designated GRB 260623A, during the sudden collapse of what is likely a star ...

Using NASA's Fermi Gamma-ray Space Telescope, Chinese astronomers have observed a gamma-ray binary system known as PSR J2032+4127. Results of the new observations, published February 3 on the arXiv ...

Could the universe’s most elusive ingredient have finally betrayed its presence? Almost a century after the first indirect clues, a faint but striking glow, detected by NASA’s Fermi Gamma-ray Space ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

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 ...
