Record-Breaking Solar Radiation Detected, Raising Physics Questions

A measurement of solar gamma rays observed by the High-Altitude Water Cherenkov Observatory Collaboration, with the Sun in the center.

A new study details the highest-energy radiation ever documented from the Sun, roughly 1 trillion times more powerful than visible light. Not only is the solar radiation stronger than expected, there’s also more of it. The researchers involved say the discovery calls for a “revised theoretical framework” to explain the excess of solar gamma rays.
