Summary

Story summary

NASA's Imaging X-ray Polarimetry Explorer (IXPE) captured observations of the supernova remnant RCW 86, which exploded around AD 185 and lies about 8,000 light-years from Earth.
IXPE mapped magnetic fields and polarized X-rays, revealing how explosion energy was distributed.
The findings provide evidence of high-speed particle acceleration and support models of supernova magnetic fields.
IXPE launched in December 2021 and continues to influence high-energy astrophysics and guide future space missions.
