Astronaut Oleg Artemyev posted beautiful cloudscape. According to NASA’s report, 67% of Earth’s surface is typically covered by clouds. The main part of Earth’s atmosphere is due to stratosphere which extends to 50km. From the image atmosphere looks thick but it only accounts for 0.8% of the Earth’s radius 6,371km.
