NASA’s Chandra and IXPE Study Pulsar in Lighthouse Nebula
This composite image, released on July 9, 2026, shows the region around a pulsar – a neutron star with a strong magnetic field that spins incredibly fast – within the Lighthouse nebula. The image contains X-ray data from NASA’s Chandra X-ray Observatory in purple, X-rays from NASA’s IXPE (Imaging X-ray Polarimetry Explorer) in blue, and […]

NASA Space Telescope Maps Magnetic Fields of ‘Lighthouse’ Pulsar
For the first time, scientists have used NASA’s IXPE (Imaging X-ray Polarimetry Explorer) to directly measure the magnetic fields of PSR J1101−6101, a pulsar located within what is often referred to as the Lighthouse Nebula. The results provide new insight into the structure of some of the most extreme objects in the cosmos, as NASA […]
