Cassiopeia A from IXPE

With polarization data from Cassiopeia A, IXPE will allow scientists to see, for the first time, how the amount of polarization varies across the supernova remnant, which is about 10 light-years in diameter. Researchers are currently working with the data to create the first X-ray polarization map of the object. This will reveal new clues about how X-rays are produced at Cassiopeia A.
