NASA's Fermi Space Telescope Explores New Energy Extremes
Fermi's Large Area Telescope (LAT) scans the entire sky every three hours, continually deepening its portrait of the sky in gamma rays, the most energetic form…
NASA's Swift Finds a Gamma-Ray Burst With a Dual Personality
Gamma-ray bursts (GRBs) are the universe's most luminous explosions, emitting more energy in a few seconds than our sun will during its entire energy-producing…
VLT observations of gamma-ray burst reveal surprising ingredients of early galaxies
After their positions have been pinned down, they are then immediately studied using large ground-based telescopes that can detect the visible-light and…
Star Packs Big Gamma-Ray Jolt
In the center of the Crab Nebula, the Crab Pulsar, a spinning neutron star left over when a supernova exploded, is pulsing out gamma rays with energies never…
'Odd Couple' Binary Makes Dual Gamma-ray Flares
The system possesses a so-far unique blend of a hot and massive star with a compact fast-spinning pulsar. The pair's closest encounters occur every 3.4 years…
Breakthrough Study Confirms Cause of Short Gamma-Ray Bursts
The state-of-the-art simulation ran for nearly seven weeks on the Damiana computer cluster at the Albert Einstein Institute (AEI) in Potsdam, Germany. It…
