Black holes eat stars and burp cosmic rays

摘要

WHITE dwarf stars shredded by black holes could explain showers of cosmic rays and neutrinos we see on Earth. Our planet is bombarded by these subatomic particles, but no one knows where they originate. Now a team led by Daniel Biehl at Deutsches Elektronen-Synchrotron in Germany suggests that they could be formed by white dwarfs being torn apart.
