Unveiling the Invisible Highways: How a Cosmic 'Lighthouse' Illuminates the Milky Way's Magnetic Field
Astronomers have, for the first time, directly mapped the magnetic field surrounding the unusual 'Lighthouse' pulsar (PSR J1101−6101) using NASA's Imaging X-ray Polarimetry Explorer (IXPE) mission. This groundbreaking discovery confirms that high-energy particles stream along magnetic field lines extending through the Milky Way, validating a long-standing prediction. The research also revealed a surprisingly orderly magnetic field, challenging existing models of magnetic turbulence and offering new insights into how these extreme cosmic objects accelerate particles and interact with their galactic environment. The findings advance our understanding of pulsars, neutron stars, and the dynamics of our galaxy's magnetic landscape.
