On the Fermi Space Telescope, a gamma-ray photon will pass through a device called the Anti-coincidence Detector, which blocks cosmic rays that might give a false signal, according to NASA.

Watch an animation of a black hole shooting jets of particles through a "collapsing star at nearly the speed of light" and ...

A groundbreaking new survey from China’s LHAASO observatory has unveiled powerful ultrahigh-energy gamma-ray emissions across ...

Gamma rays from deep space reaching Earth’s upper atmosphere is a testament to the wonders and mysteries of the universe. As scientists continue to study these high-energy rays, ...

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 ...

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.

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

Multiple space and ground-based telescopes witnessed one of the brightest explosions in space when it reached Earth on October 9. The gamma ray burst may be one of the most powerful ever recorded ...

Gamma rays travel through the vacuum of space at the speed of light, with wavelengths so minuscule that they can pass through the space within the atoms of a detector.

But this radiation has been spreading through space for eons, and it is so faint that sensitive instruments like NASA's Fermi Gamma-ray Space Telescope are required to even pick up these signals.

Our solar system was hit by a gamma-ray burst so bright, it blinded space equipment and telescopes. The gamma-ray, dubbed the "brightest of all time," hit our solar system last fall.

High energy gamma rays on the sun, as observed by NASA's Fermi Gamma-ray Space Telescope. Yellow and orange represent areas where gamma energy is more concentrated.
