Observations of a pulsar, consisting of a dead star spinning 600 times a second, and feasting on a stellar companion reveal ...

An international team of astronomers has uncovered new evidence to explain how pulsing remnants of exploded stars interact ...

NASA intends to learn more about stars, neutron stars, black holes, nebulae and other space objects by launching a new X-ray telescope satellite, the IXPE, from Florida early Thursday.

The Neutron star Interior Composition Explorer, or NICER, payload completed commissioning and calibration and all systems are working as expected.

These observations from NASA's Chandra X-ray Observatory indicate that the interiors of neutron stars might contain a unique form of ultradense matter not found elsewhere in the cosmos.

NASA's ISS-mounted X-ray telescope NICER has weighed and measured the closest pulsar to Earth. The neutron star PSR J0437 spins 174 times a second and has a mass of 1.4 suns.

NASA's X-ray space telescope IXPE has made the first observation of polarized light emerging from an outbursting magnetar, neutron stars that possess the universe's strongest magnetic fields.

New images taken by NASA's James Webb Space Telescope show young stars forming within a "toe bean" on the Cat's Paw Nebula.

But scientists were surprised when NASA's Imaging X-ray Polarimetry Explorer (IXPE) satellite last year detected that lower- and higher-energy X-rays were polarized differently, with ...
