Astronauts Could See Auroras on Mars with their Eyes

Earth's magnetosphere channels particles from solar storms into stunning auroras. Mars lacks a planet-wide magnetic field and has patchy auroras barely detectable with instruments. Or so we thought. New images captured by NASA's Perseverance Rover with its Mastcam-Z instrument show green auroras in visible light. When humans finally walk on Mars and look to the skies, they could possibly see faint auroras there, too.
