For over a decade, a star system on the verge of unleashing a deadly gamma ray burst appeared to have its guns trained on ...

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

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

WEST LAFAYETTE, Ind. -- An international team of astronomers has observed extremely rapid bursts of high-energy gamma rays from a distant galaxy, an observation that is challenging how astronomers ...

"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 ...

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 ...

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 ...

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 ...
