How We Accidentally Discovered Gamma-Ray Bursts
Gamma-ray bursts are one of the biggest mysteries in modern astronomy, but the mystery began on accident, thanks to the Cold War!

NASA | Fermi discovers giant gamma-ray bubbles in the Milky Way
Using data from NASA's Fermi Gamma-ray Space Telescope, scientists have discovered a gigantic, mysterious structure in our galaxy. This never-before-seen feature looks like a pair of bubbles extending above and below our...

NASA | Fermi Finds Radio Bursts from Terrestrial Gamma-ray Flashes
Lightning in the clouds is directly linked to events that produce some of the highest-energy light naturally made on Earth: terrestrial gamma-ray flashes (TGFs). An instrument aboard NASA's Fermi Gamma-ray Space Telescope was recently...

NASA’s Fermi Links Ghost Particle to Galaxy
Nearly 10 billion years ago, the black hole at the center of a distant galaxy produced a powerful outburst, and light from this blast began arriving at Earth in 2012. Astronomers using data from NASA's Fermi Gamma-ray Space...

NASA | Fermi Sharpens its High-Energy View - 4K
Major improvements to methods used to process observations from NASA's Fermi Gamma-ray Space Telescope have yielded an expanded, higher-quality set of data that allows astronomers to produce the most detailed census of the sky yet...

NASA | The Dual Personality of the 'Christmas Burst'
The Christmas burst, also known as GRB 101225A, was discovered in the constellation Andromeda by Swift's Burst Alert Telescope at 1:38 p.m. EST on Dec. 25, 2010. Two very different scenarios successfully reproduce features of...

NASA | Gamma-Ray "Raindrops" From Flaring Blazar
This visualization shows gamma rays detected during 3C 279's big flare by the LAT instrument on NASA's Fermi satellite. The flare is an abrupt shower of "rain" that trails off toward the end of the movie. Gamma rays are...

NASA | Best-Ever View of the High-Energy Gamma-ray Sky - 4K
This image, constructed from more than six years of observations by NASA's Fermi Gamma-ray Space Telescope, is the first to show how the entire sky appears at energies between 50 billion (GeV) and 2 trillion electron...

NASA | A Flickering X-ray Candle
The Crab Nebula, created by a supernova seen nearly a thousand years ago, is one of the sky's most famous "star wrecks." For decades, most astronomers have regarded it as the steadiest beacon at X-ray energies, but data from orbiting...

Fermi's Gamma-Ray Burst Monitor
The Gamma-ray Burst Monitor (GBM) is one of the instruments aboard the Fermi Gamma-ray Space Telescope. The GBM studies gamma-ray bursts, the most powerful explosions in the universe, as well as other flashes of gamma rays....

NASA’s Fermi Finds Record-breaking Binary Star
Using data from NASA's Fermi Gamma-ray Space Telescope and other facilities, scientists have found the first gamma-ray binary in another galaxy and the most luminous one ever seen. The dual-star system, dubbed...

NASA | Fermi Catches a 'Transformer' Pulsar
In late June 2013, an exceptional binary system containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system...

NASA | What is a Pulsar?
A pulsar is a neutron star that emits beams of radiation that sweep through Earth's line of sight. Like a black hole, it is an endpoint to stellar evolution. The "pulses" of high-energy radiation we see from a pulsar are due to a...
