NASA’s Mars Perseverance rover captured a strange and rare “blue sunset” over the Red Planet’s horizon, according to The Independent.
The US Space Agency indicated that the spacecraft obtained the image on its 842nd Martian day, last July 4, using its navigation camera located at the top of the vehicle’s mast, which helps in driving.
As the red sky began to darken and became dark, the adventurous robot turned the left navigation camera to the hazy horizon. With one shot, he had a stunning sunset, with the Red Planet’s sky glowing a wonderfully eerie, cool blue.
The Perseverance image shows the sun setting on the Martian horizon, glowing in a cold, eerie bluish-green color. It’s an image that sheds more light on the physics behind the strange sunsets, the physics of light scattering on the red planet, and how it contrasts with a similar phenomenon on Earth.
