FAST catches a real pulse from FRB 121102. Credit: NAOC The energetic phenomena known as Fast Radio Bursts (FRBs) are one of the greatest cosmic…
Roughly a century ago, scientists began to realize that some of the radiation we detect in Earth’s atmosphere is not local in origin. This eventually…
Artist’s impression of a gamma-ray burst. Credit: Carl Knox, OzGrav-Swinburne Short gamma-ray bursts are extremely bright bursts of high-energy light that last for a couple…
A detailed look at the gamma-ray sky. Credit: NASA/DOE/Fermi LAT Collaboration Star-forming galaxies are responsible for creating gamma-rays that until now had not been associated…
This illustration depicts a collapsing star that is producing two short gamma-ray jets. Just before a massive, collapsing star explodes as a supernova, we often…
When the core of massive star collapses, it can form a black hole. Some of the surrounding matter escapes in the form of powerful jets…

In space, astronauts are constantly bombarded by galactic cosmic radiation, comprised of a mixture of highly energetic ions, putting them at increased risk of radiogenic…
The physical process driving Gamma-Ray Bursts might be synchrotron radiation after all. A new analysis of Fermi/GBM archival data of gamma-ray bursts (GRB), the most…
After 20 years of searching, scientists have finally observed the gargantuan light energy — tera-electron volts — that validates their theories about Inverse Compton emission…
