A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely ...

Big thunderstorms continuously emit gamma rays that are undetectable from the ground, two studies said on Wednesday, upending what was previously thought -- and potentially pointing towards a clue ...

The "cosmic pinwheel" that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as ...

Recent flights by NASA’s ER-2 aircraft have uncovered new types of gamma rays generated by thunderstorms. These observations indicate that gamma-ray glows are more common and long-lasting than ...

and supernovae—but also by regular ol’ thunderstorms here on Earth. “Over the last decade, people have discovered that these high-energy gamma rays are present in many, many types of very ...
