caption_attribution_description: English: Original Caption Released with Image: This processed color image of Jupiter was produced in 1990 by the U.S. Geological Survey from a Voyager image captured in 1979. The colors have been enhanced to bring out detail. Zones of light-colored, ascending clouds alternate with bands of dark, descending clouds. The clouds travel around the planet in alternating eastward and westward belts at speeds of up to 540 kilometers per hour. Tremendous storms as big as Earthly continents surge around the planet. The Great Red Spot (oval shape toward the lower-left) is an enormous anticyclonic storm that drifts along its belt, eventually circling the entire planet. Suomi: Käännös alkuperäisestä kuvatekstistä: Tämän jälkikäsitellyn kuvan Jupiterista loi U.S. Geological Survey vuonna 1990 Voyagerin 1979 ottamasta kuvasta. Värejä on muokattu yksityskohtien parantamiseksi. Vaaleat, nousevat pilvivyöhykkeet ovat tummempien, laskeutuvien pilvivyöhykkeiden lomassa. Pilvet liikkuvat itään 540 km:n tuntinopeudella, länteen liikkuvien pilvimassojen nopeudet vaihtelevat. Mannerlaattojen kokoiset myrskyalueet kiertävät planeettaa. Suuri punainen pilkku (soikea kohde vasemmassa alakulmassa) on valtava pyörremyrsky, joka kiertää hitaasti planeetan pinnalla. Français&#160;: Cette photographie de Jupiter a été produite en 1990 par le U.S. Geological Survey à partir d'une photographie prise par une sonde Voyager en 1979. Les couleurs ont été améliorées afin de révéler le plus de détails possibles. Des zones claires de nuages ascendants alternent avec des bandes foncées de nuages descendants. Les nuages parcourent la planète en ceintures alternantes d'est en ouest, et vice-versa, à une vitesse de plus de 540 km/h. D'énormes tempêtes aussi grosses que des continents terrestres surgissent tout autour de la planète. La «&#160;grande tache rouge&#160;» (forme ovale en bas à gauche) est une énorme tempête anticyclonique qui glisse le long de sa ceinture, tournant perpétuellement autour de la planète.

context_page_description: Ammonia is a compound of nitrogen and hydrogen with the formula NH₃. A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water.
  Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caustic and hazardous in its concentrated form. It is classified as an extremely hazardous substance in the United States, and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.
  The global industrial production of ammonia in 2018 was 175 million tonnes, with no significant change relative to the 2013 global industrial production of 175 million tonnes.
context_section_description: Ammonia has been detected in the atmospheres of the giant planets, including Jupiter, along with other gases like methane, hydrogen, and helium. The interior of Saturn may include frozen crystals of ammonia. It is naturally found on Deimos and Phobos – the two moons of Mars.
caption: Ammonia occurs in the atmospheres of the outer giant planets such as Jupiter (0.026% ammonia), Saturn (0.012% ammonia), and in the atmospheres and ices of Uranus and Neptune.
