4 Min Read 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 [...]
Two new reports from NASA’s Commercial Satellite Data Acquisition (CSDA) program evaluate data from the Umbra X-band Synthetic Aperture Radar (SAR) satellite constellation for the NASA Earth science research and applications community. The results of these evaluations help to inform NASA program management and the user community about the quality of these commercial data for [...]
