The Tycho supernova remnant is shown in this composite image which combines infrared and X-ray views obtained with NASA's Spitzer and Chandra space observatories and the Calar Alto observatory in Spain in this handout from NASA released to Reuters December 3, 2008. The remnant was analysed more than four centuries after the star exploded. The explosion, witnessed by Tycho Brahe and other astronomers of that era, makes it the oldest ever seen in the Milky Way.(Xinhua/Reuters Photo) |
