Famous Star Explosion May Help Solve Cosmic Mystery

From Space.com

NASA’s Fermi space telescope has detected gamma rays — the highest-energy form of light — emanating from the shattered husk of Tycho’s supernova, a star that exploded in 1572. The find could help astronomers pinpoint the origin of cosmic rays, super-speedy subatomic particles that crash constantly into Earth’s atmosphere, researchers said.
