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

The NICER telescope developed a light leak in May 2023 when several thin thermal shields were damaged and let in sunlight that made the telescope useless during daylight hours.

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.

In October 2010, a neutron star near the center of our galaxy erupted with hundreds of X-ray bursts that were powered by a barrage of thermonuclear explosions on the star's surface.

NASA's Chandra X-ray Observatory has provided valuable insights into the predatory behavior of "spider pulsars," a group of deceased stars, as they consume companion stars in their vicinity.

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.

NASA researchers first discovered pulsar PSR B1509-58 in 2001. When a star runs out of fuel, it collapses into itself and forms a neutron star.
