NASA’s NICER Reveals 1st-ever Pulsar Surface Map

The video explores the study of pulsar JPO 30, located in Pisces, using NASA's NICER telescope. NICER's precise X-ray measurements have provided new insights into the size and structure of pulsars, revealing that JPO 30's appearance differs from traditional textbook depictions. The pulsar's mass affects space-time, allowing scientists to observe light from its far side. Contrary to the simple magnetic dipole model, JPO 30's hotspots are located in its southern hemisphere, with varying shapes. These findings suggest that pulsar magnetic fields are more complex than previously thought, opening new avenues for understanding neutron stars.
