Are gaps in the Andromeda galaxy filled with dark matter? This NASA telescope could find out

A simulated view of the Andromeda galaxy where Roman will search between stars to hunt dark matter.

Images created by NASA's forthcoming Nancy Grace Roman Space Telescope may allow scientists to search for dark matter between stars.

An international team of researchers believes that gaps present in strings of stars hanging from tightly packed balls of ancient stellar bodies, called globular clusters, could be influenced by dark matter clumps.
