Although neutron stars were theorized nearly a century ago and later identified through the discovery of pulsars, astronomers have only detected a small, biased sample of what is believed to be a vast population across the Milky Way galaxy. Now, researchers are planning to get creative with NASA’s Nancy Grace Roman Space Telescope to uncover and weigh these elusive objects. By measuring tiny shifts in starlight caused by their gravity, Roman may reveal a hidden population of isolated neutron stars and open a new window on extreme physics.
