NASA explains 'rainbow' spotted on the Red Planet
NASA has explained an image from the Perseverance rover that appeared to show a rainbow stretching across the red planet’s 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.
But a real rainbow is impossible on Mars, as the planet does not have the processes that create such a phenomenon on Earth.
Instead, the sight was explained by something much closer to home, at least for the Perseverance rover that took it: a lens flare as the sun hit the rover’s cameras.
The space agency explained that the colours were the result of a flare that came from the cameras that are mounted on the rover, and took the image in the first place.
The new image is one of many already sent back from Perseverance since it arrived on the planet earlier this year.
The uncanny nature of the Martian surface, which often appears unusually similar to our own world, but at the same time undeniably alien, has led people to see a number of things that aren’t actually there.
