HOUGHTON, Michigan, March 12 (TNSRes) -- Michigan Technological University issued the following news:
The highest-energy cosmic rays come from subatomic interactions within star clusters, not supernovae, say Michigan Tech physicists and collaborators.
For decades, researchers assumed the cosmic rays that regularly bombard Earth from the far reaches of the galaxy are born when stars go supernova -- when they grow too massive to support the fusion occurring at their cores . . .
