Enigma of the Absolute
This nightly geyser is spouting boiling water and expels gases in five minute intervals driven by the Yellowstone magma chamber at shallow depth. Exhaled gases of water vapor, hydrogen sulfide, carbon dioxide and carbon monoxide from volcanic activity ever since contribute important constituents as trace gases to Earths atmosphere. The hot steam in the cold air causes instantaneous condensation that perspectively extends above the sloped terrain into the eastern branch of the Milky Way. The brightest object to the left is Jupiter. To the right of the Milky Way the Scorpio constellation is visible with its red star Antares, being 700 times larger than our sun at a distance of only 520 light years.
