NASA's IXPE Captures Detailed Image of Ancient Supernova Remnant RCW 86
NASA's Imaging X-ray Polarimetry Explorer (IXPE) has captured a high-resolution image of the supernova remnant RCW 86, providing new insights into the explosion that occurred approximately 8,000 light-years away from Earth around AD 185. The image reveals unseen features of the exploded star, including a large low-density cavity in the center of the supernova.
