cosmic ray

Noun

cosmic ray (plural cosmic rays)

1. (astronomy) An energetic particle originating outside our solar system.
2. (astronomy) Cosmic radiation: a stream of cosmic rays.

Usage notes

The use of the words "ray" and "radiation" implies incorrectly that cosmic rays are electromagnetic waves, similar to light rays and X-rays; cosmic rays were so named before their nature was known.
