Around 11,000 light years from Earth is a supernova remnant called Cassiopeia A. Details of the cosmic explosion, first discovered by astronomers in 1948, have been seen in a new light thanks to a collaboration between NASA’s Chandra X-ray Observatory, the James Webb Space Telescope and the Spitzer Space Telescope, which observe in different wavelengths.
