Space Telescopes
NASA's upcoming Nancy Grace Roman Space Telescope may detect dozens of isolated neutron stars in the Milky Way through gravitational microlensing. A new study shows the observatory could measure the masses of these otherwise invisible objects. Researchers expect the mission to provide the first large sample of such stars detected solely by their gravitational effects.

Astronomers have identified the source of unusual X-rays from the bright star gamma-Cas as a hidden white dwarf companion siphoning material from it. High-resolution data from the XRISM space mission confirmed that the emissions arise from matter heating up as it falls onto the unseen star. The discovery ends a puzzle that has intrigued scientists since the 1970s.
