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.

NASA's Perseverance rover recently captured a photo of green auroras shining in the Martian sky for the first time. The alien light show, previously assumed to be impossible, could be visible to future astronauts.

NASA’s Perseverance rover has detected the first aurora at Mars that's visible to the human eye, good news for future astronauts who can savor the view on the red planet. European and U.S. scientists reported that the green aurora in the dusty Martian sky was generated by a solar storm last year and had three days' advance notice to set aside viewing time with the rover’s cameras.
