NASA's Roman Space Telescope Could Reveal Millions of Invisible Neutron Stars Hiding Across the Milky Way

A new study published in Astronomy and Astrophysics on May 15, 2026 estimates that NASA's Nancy Grace Roman Space Telescope, due to launch in early September, could detect dozens of solitary neutron stars by measuring the tiny gravitational bend they impose on the light of more distant stars. The technique — astrometric microlensing — would for the first time allow astronomers to weigh individual neutron stars not bound to a companion. Researchers think the Milky Way may host tens to hundreds of millions of such objects, of which only a few thousand have ever been seen.
