A Multiwavelength View of Celestial Fireworks
14 Julio 2008: Around May 1, 1006 A.D., observers from Africa to Europe to the Far East witnessed and recorded the arrival of light from what is now called SN 1006, a tremendous supernova explosion caused by the final death throes of a white dwarf star. This image of SN1006 is a composite of optical, radio, and X-ray data of the full shell of the supernova remnant. The optical data was obtained at the University of Michigan’s 0.9-meter Curtis Schmidt telescope at Cerro Tololo Inter-American Observatory in Chile. H-alpha, continuum-subtracted data were provided by FrankWinkler (Middlebury College) et al. The object has an angular size of roughly 30 arcminutes (about the size of the full Moon), and a physical size of 60 light-years, based on its distance of nearly 7,000 light-years.
