New images and shows taken over 16 minutes by the Mastcam Instrument of NASA’s Curiosity Rover on January 17, 2025 Night or in twilight cloudsin the atmosphere of Mars. Sometimes these clouds create rainbows of color, creating rainbow clouds and mother clouds. If it is too faint to be visible in the daytime, the clouds will be particularly high and only visible when the evening falls.

Mars clouds are made of either water ice or carbon dioxide ice at higher altitudes and lower temperatures.
The latter is the only kind of cloud observed on the red planet, producing rainbow colors, and can be seen near the top of the new image at an altitude of 60-80 km (37-50 miles).
It also appears that white feathers fall into the atmosphere on a low ride 50 km (31 miles) from the surface before evaporating due to rising temperatures.
Temporarily visible at the bottom of the image are water ice clouds moving in the opposite direction about 50 km of the curiosity rover.

“When I first saw these rainbow clouds, I always remember, but at first I was sure it was a few colour artifacts,” said the Atmospheric Scientist at the Institute of Space Science. said one Dr. Mark Lemon.
“It’s now predictable, so you can plan your shots ahead of time. Clouds appear at the exact same time.”
“Each sighting is an opportunity to learn more about the particle size and growth rates of Mars clouds, which will provide you with more information about the planet’s atmosphere.”
“The potential source of clouds can be gravitational waves, which can cool the atmosphere.”
“We weren’t expecting carbon dioxide to condense into ice here, so we’re cooling until something is likely to happen.”
“However, the gravitational waves on Mars are not fully understood, and we are not entirely aware of what the Twilight clouds are formed in one place and not elsewhere. “
