NASA astronomers have measured and mapped polarized X-rays from the remnants of a stellar explosion for the first time, providing new insight into the nature of supernova remnants.

The US space agency (NASA) announced on October 19 that astronomers had for the first time measured and mapped polarized X-rays from the remains of a stellar explosion (supernova) using X-ray polarimetry probe (IXPE).
This is the result of observations Cassiopeia A supernova remnantoffering a new perspective on the nature of supernova remnants.
The Cassiopeia A supernova is the first object observed by XPPE since data collection began.
Scientist Pat Slane of the Harvard-Smithsonian Center for Astrophysics, who led the study of the IXPE supernova remnant, said: “Without IXPE, we would have missed important information about objects like Cassiopeia A. This result tells us about a fundamental aspect of the debris from this exploding star: magnetic field activity.”
Launched into space on December 9, 2021, IXPE is a collaborative project between NASA and the Italian Space Agency. This is the first satellite capable of measuring X-ray polarization with such sensitivity and clarity.
