REMNANTS OF CASSIOPEIA A (3D)
This video shows a three-dimensional animation of the supernova remnant Cassiopeia A, based on data from the Chandra X-ray Observatory and the Spitzer Space Telescope. Green indicates mostly X-ray emissions from iron; yellow reveals mostly X-ray, infrared and visible-light emissions from argon and silicon; and red is the coolest debris, seen in infrared. Blue depicts X-rays from the outer blast wave.
