Aug 6, 2023 · In a record-breaking discovery, scientists detected our very own sun emitting an extraordinary amount of gamma rays — wavelengths of light known to carry the most energy of any other...
May 24, 2021 · Hundreds of gamma ray signals were detected with ultra-high energies, with the most powerful signals crossing the Peta-electronvolt (PeV) threshold – much higher than thought possible in...

Gamma rays have the shortest wavelengths and highest energies among the electromagnetic spectrum. Their wavelengths range from about 10 picometers (pm) to less than 1 femtometer (fm). In contrast, X-rays have longer wavelengths, typically ranging from 0.01 to 10 nanometers (nm).
Nov 20, 2019 · NASA’s Hubble Space Telescope has given astronomers a peek at the location of the most energetic outburst ever seen in the universe — a blast of gamma-rays a trillion times more powerful than visible light.
Mar 30, 2024 · The attenuation of X-rays and gamma rays in matter depends on the energy of the radiation and the density and atomic number of the material. Higher-energy photons are more penetrating, while denser, higher-Z materials are more effective at stopping these types of radiation.
Jan 14, 2020 · Nine sources of extremely high-energy gamma rays comprise a new catalog compiled by researchers with the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory. All produce gamma rays with energies over 56 trillion electron volts (TeV) and three emit gamma rays extending to 100 TeV and beyond, making these the highest-energy sources ever observed in our galaxy. The catalog helps to explain ...
