The Crab Nebula is what remains of a supernova observed in the year 10 54, with a dense, spinning neutron star -- a pulsar -- at its heart. 
 
Contiguous circles and free-forming shapes in hues of purple, yellow, green, blue, and white. 
 
Text, Despite many studies, there is still more to be discovered in the Crab Nebula, as NASA's Imaging X-ray Polarimetry Explorer (IXPE) has revealed. An image of a white-hot center in the pulsar surrounded by layers of pink and purple gases against a black sky. . 
 
Text, Only I X P E can study the Crab's X-ray polarization, measuring the organization of electromagnetic fields. 
 
Scientists were able to measure X-rays from the nebula and also the sphere of magnetic fields around the pulsar itself.

Text, Areas of magnetic field turbulence were more patchy and asymmetrical than expected. 
 
The I X P E observations do not align with computer models, opening up an intriguing new puzzle for astronomers to investigate.
