The brilliant remnants of a supernova
The brilliant remnants of a supernova (above) were captured in a composite image by NASA's Chandra and Spitzer space observatories, which partnered with Spain's Calar Alto observatory.
The green and yellow areas represent a hot cloud of expanding debris, while the outer shock wave is in blue. The red splotches are dust radiating from the supernova.
The star explosion was witnessed by Danish astronomer Tycho Brahe and his peers in the 1500s.
