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.

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 ...

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'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 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 ...

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.

How about the “ghostly cosmic hand” of a star corpse that exists 16,000 light-years away from Earth? With the help of NASA‘s newest X-ray telescope, the Imaging X-ray Polarimetry Explorer ...

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 ...
