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 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.

Using European and Japanese/NASA X-ray satellites, astronomers have seen Einstein's predicted distortion of space-time around three neutron stars, and in doing so they have pioneered a ...

NASA on Spider Pulsars. NASA noted that a pulsar is the dense core left behind when a massive star undergoes a gravitational collapse, forming a neutron star. Rapidly rotating neutron stars can ...

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 Rossi X ...

NASA has selected two new space missions for launch in 2017: a satellite that can scan the entire sky for exoplanets and a space station experiment that can monitor cosmic X-ray emissions.

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.

May 6, 2025 — Astronomers have probed the physical environment of repeating X-ray outbursts near monster black holes thanks to data from NASA's NICER (Neutron star Interior Composition Explorer ...

A long observation with NASA’s Chandra X-ray Observatory revealed important new details of a neutron star that is spewing out a wake of high-energy particles as it races through space.

The three exceptionally cool neutron stars identified are PSR J0205+6449, PSR B2334+61, and CXOU J0852−4617, located within the supernova remnants 3C 58, SNR G114.3+0.3, and SNR Vela Jr ...

NASA's Chandra X-ray Observatory captured images of a speeding pulsar in the midst of an exploded star. The pulsar is estimated to be traveling at a speed of well over 1 million miles per hour (MPH).
