A team of astronomers have compiled 12.5 years of data from the Fermi Gammy-ray Space Telescope to form a gamma-ray pulsar timing array, a system of cosmic lighthouses that could help reveal ...

To highlight the range of gamma-ray sources in this new census, the Fermi team created a "Top 10" list. Five of the 10 "top" gamma-ray sources are within the Milky Way. [Top 10 Strangest Things in ...

HAIZI MOUNTAIN, China — Astrophysicist Cao Zhen opens a steel hatch on a windswept Tibetan Plateau and climbs down a ladder into inky darkness. His flashlight picks out a boat float… ...

Colossal gravitational waves—trillions of miles long—found for the first time. Detected by studying rapidly spinning dead stars, these giant ripples of spacetime likely came from merging ...

Sources of high-energy cosmic rays in the vicinity of the microquasar V4641 Sag, on the left with energies above a ...

The common designations are radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays. Gamma rays fall in the range of the EM spectrum above soft X-rays .

Elusive gamma ray bursts . For these Eastern Europeans, naturally skilled in the DIY approach to make up for their lack of financial resources, cubesats appeared like a gift from the heavens.

During its first year of operations, NASA's Fermi Gamma Ray Space Telescope mapped the extreme sky with unprecedented resolution and sensitivity. It captured more than one thousand discrete ...

The gamma-ray data are too sparse to allow the discovery of millisecond pulsations from unidentified sources, and the radio discoveries would have been delayed by years if they had to continue ...

On November 12, 2023, a huge burst of gamma radiation hit the European Space Agency’s orbiting INTEGRAL satellite.The rush of radiation lasted just one-tenth of a second, but immediately, an ...
