Supernova remnant is source of extreme cosmic particles

Astronomers have long sought the launch sites for some of the highest energy protons in our galaxy. Now, a study using 12 years of data from NASA’s Fermi Gamma-ray Space Telescope confirms that a remnant of a supernova, or star explosion, is just such a place, solving a decade-long cosmic mystery.
