Jamie Carter is an award-winning reporter who covers the night sky. A massive burst of gamma rays produced by the explosion of a star almost two billion light-years away was so powerful that it ...

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 ...

As a result, they detected increased gamma-ray activity from this source, including a strong outburst. The finding is reported in a research paper published on the arXiv preprint server.

The highly energetic explosion was initially attributed to a burst of gamma rays emitted either by the collision of two neutron stars or from the death of a massive star. Soon, however ...

Gamma-ray bursts are the most energetic explosions in the universe, releasing as much as a quintillion (10 followed by 18 zeroes) times the energy that is radiated by the sun.

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...
