Astronomers Shed Light on Cause of Cosmic Rays
From Times Staff and Wire Reports
An international team of astronomers believe they have solved a mystery that has been perplexing scientists for 100 years -- the origin of cosmic rays.
Using four telescopes in Africa, the scientists produced an image showing that cosmic rays could emanate from the remnant of a supernova, an explosion of a star at the end of its life.
Scientists had long thought that supernova explosions were the source, but did not have evidence to support it.
The latest finding was reported in the current issue of the journal Nature.
