Mysterious objects at the edge of the electromagnetic spectrum

The human eye is crucial to astronomy. Without the ability to see, the luminous universe of stars, planets and galaxies would be closed to us, unknown forever. Nevertheless, astronomers cannot shake their fascination with ...

Despite extensive analysis, Fermi bubbles defy explanation

(Phys.org) —Scientists from Stanford and the Department of Energy's SLAC National Accelerator Laboratory have analyzed more than four years of data from NASA's Fermi Gamma-ray Space Telescope, along with data from other ...

NASA's Fermi mission sees no gamma rays from nearby supernova

A nearby supernova in 2023 offered astrophysicists an excellent opportunity to test ideas about how these types of explosions boost particles, called cosmic rays, to near light-speed. But surprisingly, NASA's Fermi Gamma-ray ...

Integral challenges physics beyond Einstein

(PhysOrg.com) -- ESA's Integral gamma-ray observatory has provided results that will dramatically affect the search for physics beyond Einstein. It has shown that any underlying quantum 'graininess' of space must be at much ...

Red Crucifix sighting in 774 may have been supernova

(Phys.org) -- A supernova may have actually been the mysterious "Red Crucifix" in the sky that is cited in the Anglo Saxon Chronicle for the year 774. New correspondence between a university student and Nature carries interesting ...

Longstanding mystery of matter and antimatter may be solved

An element which could hold the key to the long-standing mystery around why there is much more matter than antimatter in our Universe has been discovered by a University of the West of Scotland (UWS)-led team of physicists.
