NASA's Fermi Space Telescope has failed to see gamma rays from a nearby supernova that should be created when it generates the high-energy cosmic rays that bombard Earth in their trillions.

Deep within the Milky Way’s core, researchers have uncovered cold gas clouds racing through a superheated galactic wind.

Astronomers analyzing 13 years of data from NASA's Fermi Gamma-ray Space Telescope have found an unexpected and as yet unexplained feature outside of our galaxy. January 11, 2024. 2.

NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA explains. Credit: NASA Goddard Space Flight Center ...

Today, Fermi has identified more than 300 of them. An international team of experts combed through a decade of Fermi data in search of something specific: a gamma-ray eclipse.

The cosmos comes alive in an all-sky time-lapse movie made from 14 years of data acquired by NASA's Fermi Gamma-ray Space Telescope. Our sun, occasionally flaring into prominence, serenely traces ...

Jul 26, 2024: Fermi telescope finds new feature in brightest gamma-ray burst yet seen (Nanowerk News) In October 2022, astronomers were stunned by what was quickly dubbed the BOAT — the ...

The team combined 13 years of gamma ray data from NASA's Fermi Large Area Telescope to analyze the cosmic gamma-ray background. The researchers found a gamma-ray dipole, but its peak was located ...

But surprisingly, NASA’s Fermi Gamma-ray Space Telescope detected none of the high-energy gamma-ray light those particles should produce. On May 18, 2023, ...

NASA's Fermi Gamma-ray Space Telescope has found a trove of 294 gamma-ray-emitting pulsars, with an additional 34 candidates awaiting confirmation, marking a significant leap in our understanding ...

When the BOAT first erupted in 2022, it saturated most of the space-based gamma-ray detectors, including the Fermi Space Telescope, making them unable to measure the most intense part of that blast.

Pulsars are some of the most extreme and fascinating objects in the universe, and NASA's Fermi Space Telescope has just unlocked a new way to study them.
