AI detects 1,210 new potential gravitational lenses in the search for dark matter


AI has identified more than 1,2o0 new possible gravitational lenses, which could help unravel the mysteries of dark matter. The lenses are formed when a vast amount of matter — like a cluster of galaxies — bends the direction of light traveling from more distant galaxies. The lenses then typically appear as arcs and streaks. These images can help scientists infer the existence of dark matter — which the naked eye can’t see — by observing its gravitational effects on the visible matter. Unfortunately, they’re seriously hard to spot. “Only when a galaxy is hidden directly behind a giant galaxy is a…
