Beryllium-10 is a radioactive isotope that is continuously produced by cosmic rays interacting with Earth 's atmosphere.

It's unknown where the sudden surge came from, but researchers have a few ideas.

The origin of this anomaly is yet unknown, but because our Sun 's activity probably wasn't strong enough to create such a long-lasting surge, the team suspects Earth 's protection against interstellar cosmic rays may have changed roughly 10 million years ago .

Only time will tell if the bllium blip is a regional or global phenomenon.
