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 · Astronomers using the Large High Altitude Air Shower Observatory (LHAASO) in China have now detected gamma rays with energies higher than 1 PeV – that’s 1,000 TeV, or 10 times higher than the...

May 11, 2023 · GRB 221009A, the most energetic gamma-ray burst ever recorded, released 1,000 times more energy than the Sun’s lifetime output. Observed with the VLT and James Webb Space Telescope, this event left scientists puzzled about gamma-ray bursts’ nature and the possible absence of an accompanying supernova. Credit: Soheb Mandhai.
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 ...
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.
Gamma rays typically have higher energy than X-rays. [31] The conventional distinction between X-rays and gamma rays has changed over time. Originally, the electromagnetic radiation emitted by X-ray tubes almost invariably had a longer wavelength than the radiation (gamma rays) emitted by radioactive nuclei. [32]
