Nuclear reactions are a major source of gamma rays. When an unstable uranium nucleus splits in the process of nuclear fission, it releases a lot of gamma rays in the process. Fission is used in both ...

Maps from the Fermi Gamma-ray Space Telescope literally show the universe in a different light. Today Fermi’s Large Area Telescope (LAT) collaboration released the latest data from nearly seven years ...

Previous gamma-ray telescopes have also seen this light that fills the background of the cosmos. ... Symmetry magazine, Scientific American, Nature News, Physics World, and others.

Study reveals a remarkable symmetry in black hole jets Date: December 13, 2012 Source: NASA Summary: Black holes range from modest objects formed when individual stars end their lives to behemoths ...

Light from some of the universe's most energetic explosions is allowing scientists to probe the nature of space-time, according to new observations of so-called gamma-ray bursts from the Japanese ...

Study reveals a remarkable symmetry in black hole jets ... Astronomers examining the properties of black hole jets compared 54 gamma-ray bursts with 234 active galaxies classified as blazars and ...

Light from some of the universe's most energetic explosions is allowing scientists to probe the nature of space-time, according to new observations of so-called gamma-ray bursts from the Japanese ...

The gamma-ray brightness obtained with Fermi, Swift, and other observatories told the scientists how much light the jets radiate. Radio and X-ray observations allowed them to determine the power ...

Studying three gamma-ray bursts with significantly more precision than ever before, Toma and his team found no change in the polarization of the photons, implying that the symmetry is consistent ...
