Press Releases

Gamma-ray bursts are the most energetic phenomenon known to humankind. Although short-lived, they outshine stars and even galactic quasars. They usually display energies in the region of tens of giga-electron-volts, but for the first time, researchers discovered a gamma-ray burst in the region of a tera-electron-volt. This level of energy has long been theorized, and this study demonstrates these energies might actually be more common than once thought.
