"NASA's Roman Telescope: Probing Andromeda's Dark Matter Gaps"

NASA's upcoming Nancy Grace Roman Space Telescope is set to launch in 2027 and may help scientists search for dark matter between stars in the Andromeda galaxy. An international team of researchers believes that gaps in stellar streams, influenced by dark matter clumps, could provide clues about this elusive substance. The telescope's wide-field instrument will produce images 200 times the size of those created by the Hubble Space Telescope, allowing it to investigate dark matter haloes and smaller "sub-haloes" around galaxies. This research could shed more light on the nature and properties of dark matter.
