This area is located in the north of Mars, one of the coldest places on the planet, where the temperature reaches -150 ° C. According to the space agency, it is precisely this variation in temperature that explains its color.

“In this false-color image, areas with cooler temperatures are recorded in bluer tones, while warmer features are depicted in yellows and oranges. Thus, the dark, sun-warmed dunes glow gold.” .
