Cosmic Lighthouse Unlocked: Advanced Space Telescope Maps Magnetic Fields of Extreme Pulsar

Astronomers have successfully mapped the magnetic fields of PSR J1101−6101, a rapidly spinning pulsar located within the “Lighthouse Nebula.” Utilizing the Imaging X-ray Polarimetry Explorer (IXPE), researchers directly measured the polarization of X-rays emitted by this extreme stellar remnant. The findings, published in the Astrophysical Journal, confirm long-standing theories about how high-energy particles escape the […]
