Cassiopeia A with layering showing filamentary structures of dust and gas

Cassiopeia A, or Cas A, is a supernova remnant located 10,000 light-years away in the constellation Cassiopeia and is the remnant of a once massive star that died in a violent explosion roughly 340 years ago. This image layers infrared, visible and X-ray data to reveal filamentary structures of dust and gas.
