This stunning visualisation of Cassiopeia A, the result of an explosion approximately 330 years ago, uses X-ray data from Chandra, infrared data from Spitzer and pre-existing optical data from NOAO’s 4-m telescope at Kitt Peak and the Michigan-Dartmouth-MIT 2.4-m telescope. The neutron star left over from the stellar blast is an artist’s illustration (Courtesy NASA/CXC/D Berry; Model: NASA/CXC/MIT/T Delaney et al.)
