Latest Fermi Gamma-ray Space Telescope Stories
In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed.
A long-lasting gamma-ray burst that was first observed last year contained traits similar to those expected from explosions of some of the earliest stars in the universe, claims a new study appearing in The Astrophysical Journal.
All across the Universe high-energy charged particles are found racing in all directions. The source of these particles, collectively called cosmic rays, is masked by the interstellar magnetic field that bends their paths, making them nearly impossible to directly trace.
The HESS-II (High Energy Stereoscopic System) telescope in Namibia has detected gamma rays of only 30 Giga electron volts (GeV) from the Vela pulsar.
Astronomers using the NASA Fermi Gamma-ray Space Telescope to study what they thought were two different classes of black-hole-powered galaxies known as blazars now believe that they may be one and the same.
A new study of gamma-ray light from the center of our galaxy makes the strongest case to date that some of this emission may arise from dark matter, an unknown substance making up most of the material universe.
Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary system that contain rapidly spinning neutron stars, also known as pulsars.
New research from an international team of researchers using NASA's Fermi telescope reports the first-ever gamma ray study of the cosmic phenomenon.
Einstein@Home volunteers find four Gamma-ray pulsars and shed light on another part of the galaxy
- Stoppage; cessation (of labor).
