The Hubble eXtreme Deep Field (XDF) captures a tiny patch of sky in the Fornax constellation, revealing thousands of galaxies, some over 13 billion years old. This Hubble image captures HH111, a rare ...

"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 ...

Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

Highly energetic explosions in the sky are commonly attributed to gamma-ray bursts. We now understand that these bursts ...

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 ...

The 25 ground-based and orbiting telescopes that comprise the EHT saw the outburst as high-energy light called gamma rays. Not only was this the first time M87* had flared since 2010, but the ...

This site presents the energy and photon intensity of gamma rays as seen in thermal-neutron capture in two tables, one in ascending order of gamma energy and a second organized by Z, A of the target.
