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 ...

In other words, we’ll soon have a record-breaking observatory for studying gamma ray sources—some of the most energetic and mysterious objects in the universe. The observatory’s full name is ...

"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 ...

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 ...

"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 ...

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