NASA's Perseverance rover has observed an aurora on Mars in visible light for the first time, with the sky glowing softly in green in the first viewing of an aurora from any planetary surface other than Earth.

NASA's Perseverance rover has detected the first aurora at Mars that's visible to the human eye. That's good news for future astronauts who can savor the view on the red planet.

NASA's Perseverance rover has captured an aurora in the night sky for the first time from the Martian ground. Scientists have known for two decades that Mars' skies have auroras, too, but these curtains of undulating light had only been detected in ultraviolet — light that is invisible to the naked eye — until now.
