New research suggests that the largest cosmic structure is even bigger and closer to Earth than we knew. It goes against ...

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 ...

Gamma-ray bursts (GRBs) are the most energetic events ever observed in the universe. These powerful outbursts can shine a ...

"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 ...

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 ...

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 ...

Four new gamma-ray millisecond pulsars have been detected using the Murriyang radio telescope. These pulsars, with spin periods between 1.86 and 3.67 milliseconds, were identified from 80 gamma ...

IT has long been known that some of the radio-elements emit a penetrating type of X-rays known as the gamma rays. It is clear that these radiations arising from the nucleus of the radioactive atom ...

An curved arrow pointing right. NASA's Fermi Gamma-ray Space Telescope can now detect solar flares occuring on the side of the sun it cannot see. This could help scientists better understand solar ...
