Latest Fermi Gamma-ray Space Telescope Stories
A team of scientists hope to trace the origins of gamma-ray bursts with the aid of giant space 'microphones'.
New analysis of high energy blasts from a magnetar has resulted in the discovery of underlying signals related to seismic waves rippling throughout the highly magnetized neutron star.
Extremely detailed images produced using radio telescopes spread throughout Europe and the US have allowed researchers to pinpoint the exact locations in a stellar explosion where gamma rays are emitted.
When the most massive stars explode as supernovas, they don't fade into the night, but sometimes glow ferociously with high-energy gamma rays. What powers these energetic stellar remains?
NASA's Fermi and Aqua satellites captured two different views of bursts of strength show by Hurricane Julio as it intensified. NASA's Fermi satellite saw a gamma-ray flash from Julio, while NASA's Aqua satellite saw Julio become more structurally organized as a hurricane.
WASHINGTON, July 31, 2014 /PRNewswire-USNewswire/ -- Observations by NASA's Fermi Gamma-ray Space Telescope of several stellar eruptions, called novae, firmly establish these relatively common
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.
