The Curiosity Mars -Road took new pictures on which you can see green and red clouds on Mars. According to Phys. Org, the pictures were taken within 16 minutes January 17. You can see silver or gloomy clouds on them, which are painted in color, scattering the light of the setting sun.

Sometimes on such clouds you can see a whole rainbow of flowers that turns them into " They are too weak to be seen in daylight, so they are observed only when the clouds are high enough and evening occurs.

Martian clouds consist either of water ice, or at large heights and? at lower temperatures - from ice from carbon dioxide. At the same time, the latter are the only Martian clouds that acquire a rainbow coloring. Clouds that are on new images are at an altitude of 60-80 kilometers.

Clouds also take the shape of white loops that fly in an atmosphere at a height of about 50 kilometers above the surface, and then evaporate due to an increase in temperature. For a short time, in the lower part of the images, clouds of water ice appear, moving in the opposite direction about 50 kilometers above the margin.

For the first time twilight clouds on Mars were noticed by the NASA Pathfinder mission in 1997. Curiosity was not able to see them until 2019. New pictures became the fourth observation of this type of clouds by the Mars -Road.

One of the puzzles is why twilight clouds from ice dioxide ice were not seen in other places on Mars. Curiosity, landing in 2012, is located on Mount Sharp in Gale Crater, south of the Martian Equator. Pathfinder landed in the Ares Valley, north of the equator. The NASA Persevrance Mars -Road, located in the Ezero crater in the Northern Hemisphere, did not see any twilight clouds from the ice of carbon dioxide since its landing in 2021.

According to scientists, gravitational waves that cool the atmosphere can be a possible source of the appearance of such clouds.

Earlier, the Persevrance Mark Road took a sample of the breed, the texture of which, according to scientists, “is not like anything that we saw before”. Kern, known as Silver Mountain, was placed in the phone so that it could be transferred to the ground and studied in the laboratory.
