Amaterasu particle, one of highest-energy cosmic rays ever detected, is coming from an apparently empty region of space

Why is life built from molecules with preferred orientation? There’s a chance cosmic rays are to blame.

The results indicate that cosmic ray electron count rates are strongly influenced by the solar modulation.

An unusual "heartbeat" coming from a cosmic gas cloud beats along in time with the pulses of a black hole. Researchers remain puzzled as to what the unusual long-distance relationship is between the two.

Scientists think they’ve tracked down a source of mysterious high-energy cosmic rays that have been puzzling for over a century. The trail of a “ghost particle" detected at the South Pole pointed the way.

Astronomers have spotted a strange blast of gamma radiation from space that defies categorisation, and it may mean a gap in our understanding of how black holes form
