Pictures of a "constantly icy" martic crater reveal a distant yet fascinating winter wonderland.
What appears to be a bowl of fresh snow in this image released by the European Space Agency (ESA) on Thursday (December 20) is actually an ice source that cools the air that is moving over it, government officials said in a statement.
Ice is found in the deepest parts of this image, called Korolev Crater, and when the air moves over the ice it cools and lowers and produces cold air just above the cold deposit.
ESA officials called this phenomenon a "cold trap" because they air act as a shield to keep the crater "permanently icy."
Korolev Crater is located 82 kilometers (51 miles) and is located just south of terrain that winds around Olympia Undae, Mars & # 39; northern polarlock. The crater floor can reach the depth of two kilometers below its rim deeper than the Earth's Grand Canyon.
