Cosmic rays reach the Earth from 7,500 light years away

07-04-2018


Today’s Video of the Day from NASA Goddard features Eta Carinae, the biggest and brightest stellar system within 10,000 light years of our planet.

New research based on data from the NuStar Space Telescope suggests that interaction between the system’s two massive stars creates cosmic rays that reach the Earth at nearly the speed of light.
