DOI: 10.1063/1.3071042
What appears to be the fourth independent record of the Crab nebula supernova in 1054 was discovered in a cave in northern California, according to Stephen Maran of NASA’s Goddard Space Flight Center. The American Indian petroglyph consists of a drawing of a sphere and a crescent; the sphere is thought to represent the supernova and the crescent, the moon. The findings were reported at the Michigan State Meeting of the American Astronomical Society in August.
