A space telescope orbiting Earth just picked up the same strange signature buried in every kind of cosmic ray it can detect — and it’s a fingerprint physicists have been quietly waiting on since 1912

Cosmic rays were first discovered in 1912 by the Austrian physicist Victor Hess, who conducted a series of balloon flights into the upper atmosphere and demonstrated that the level of ionizing radiation in the air increased with altitude rather than decreasing, as the prevailing terrestrial-radioactivity hypothesis would have predicted. The radiation, Hess concluded, was coming […]
