7 April 2021, 12:38 pm EDT By NASA Perseverance rover ( Youtube/ UNTV News and Rescue ) Space agency NASA has explained an image from the Perseverance rover that appeared to show a rainbow stretching across Mars' sky. The image appeared strangely akin to one that might be taken from Earth: a rainbow rising from the ground and ascending up into the air, contrasted against the harsh yellow of the rest of the image taken from the red planet. NASA explains "rainbow" in Mars However, a real rainbow is impossible on Mars, as the planet does not have the processes that can create rainbows, unlike here on Earth.
