For over a decade, a star system on the verge of unleashing a deadly gamma ray burst appeared to have its guns trained on Earth. The so-called "Death Star," which is also famed for looking like a ...

An international team of astronomers reports the detection of four new gamma-ray millisecond pulsars using the Murriyang ...

It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

"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 ...

An unusual gamma-ray burst has challenged existing astrophysical models, leaving scientists searching for answers. This deep-space event defies expectations, hinting at new cosmic processes we may ...

"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 ...

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 ...

This database offers a variety of tables for all natural elements and includes the following data: isotopic composition, thermal radiative cross section (total and partial), Westcott g-factors, energy ...
