ICYMI NASA’s Imaging X-Ray Polarimetry Explorer (IXPE) released its first science image in Feb. Its first target was Cassiopeia A, the remains of a star that exploded in the 17th century. IXPE is on a quest to study some of the most mysterious & extreme objects in the universe – the remnants of supernova explosions, powerful particle streams spit out by feeding black holes, and more.
