Surprising X-ray view of wreckage from a dying star

The polarization of X-rays coming from the remains of a distant exploded star has been measured and mapped for the first time by astronomers.

The results collected from the stellar wreckage known as Cassiopeia A (Cas A) could shed new light on the nature of young supernova remnants and their magnetic fields, which can accelerate particles to near the speed of light.
