Understanding Rare Lightning-Triggered Gamma Rays

In the western Utah desert, the Telescope Array sprawls across an area the size of New York City, waiting for cosmic rays. The facility detects the high-energy particles that collide with Earth’s atmosphere constantly; the cosmic rays trigger the 500-plus sensors once every few minutes. While pouring over data in 2013, Telescope Array physicists discovered ...
