This image of the supernova remnant Cassiopeia A combines some of the first X-ray data collected by the Imaging X-ray Polarimetry Explorer (magenta) with high-energy X-ray data from the Chandra X-Ray Observatory  blue). IPXE is a collaboration between NASA and the Italian Space Agency. Studying the polarization of X-rays reveals the physics of objects and can provide insights into the high-temperature environments where they were created.
