The "cosmic pinwheel" that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as ...

ESA’s Integral observed space for 22 years, uncovering gamma-ray bursts, black holes, and gravitational waves.

"The LAT observed a pronounced enhancement in the gamma-ray activity from the direction of the source on 2022-12-08 and on 2023-05-01," the paper reads. LAT monitoring of 3C 216 recorded a strong ...

A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely ...

"This field did not exist before 1989 when the first gamma ray source was detected. At that point, we knew of four sources in the world," said Dave Kieda, professor in the Department of Physics ...

"We would like to understand the difference between these systems, which holds the clue to understand just how many cosmic rays are produced in the jets of microquasars." ...

Gamma rays are much shorter in wavelength than visible ... billions of stars and then quickly fades away. What could be the source of these mind-boggling bursts? But it now appears that certain ...

Gamma rays originate from a variety of sources in both the Marvel Universe and the real world. Primary among non-fictional cosmic gamma-ray sources, are supernovas, neutron stars, and gamma-ray ...

An artist’s concept of the famous Wolf-Rayet 104 “pinwheel star,” previously nicknamed the “Death Star.” New research ...

The Science White Paper of the Einstein Probe (EP) mission, led by the Chinese Academy of Sciences (CAS) and jointly developed with the European Space Agency (ESA), the Max Planck Institute for ...
