Description:
The Earth’s atmosphere is showcased in this highly oblique shot of the Earth taken from space. The atmosphere, composed of 78 percent nitrogen, 21 percent oxygen and 1 percent other constituents, shields us from falling meteors, as well as nearly all harmful radiation coming from the sun and other stars. The upper atmosphere also contributes to weather and climate on Earth. Public domain; Courtesy of NASA/JPL/UCSD/JSC.
