There appear to be too many gamma rays coming from the sun. New higher-energy measurements reveal that this excess continues for a bit, then disappears — a cutoff that could help clarify what’s going on. The post Strange Solar Gamma Rays Discovered at Even Higher Energies first appeared on Quanta Magazine
In 2019, researchers announced that something appeared to be off with the sun. After 10 years of observations, they had concluded that the sun’s high-energy radiation was seven times more abundant than expected. Now a new study based on even higher-energy data has sharpened the picture. Researchers found that the solar gamma-ray excess persists at higher energies. It then drops off at the topmost…
