caption_attribution_description: English: Ultraviolet image of Venus' clouds as seen by the Pioneer Venus Orbiter (February 26, 1979). The immense C- or Y-shaped features which are visible only in these wavelengths are individually short lived, but reform often enough to be considered a permanent feature of Venus' clouds. The mechanism by which Venus' clouds absorb ultraviolet is not well understood. Русский: Фотография Венеры, сделанная КА Пионер 26 II 1979 в ультрафиолетовом диапазоне. Огромные C- и Y- образные структуры, видимые только в этом диапазоне, недолговечны, но образовываются достаточно часто, чтобы рассматриваться как постоянная особенность венерианских облаков. Механизм поглощения ультрафиолета венерианскими облаками пока недостаточно изучен. Polski: Widok wenusjańskich chmur w paśmie ultrafioletu, widziany z sondy "Pioneer Venus Orbiter". Wielkie układy w kształcie liter "C" lub "Y", widoczne tylko w tej długości fal pojawiają się na krótko, ale są obserwowane na tyle często, że mogą być postrzegane, jako stała cecha chmur Wenus. Mechanizm, dzięki któremu chmury te pochłaniają ultrafiolet, nie jest jeszcze zbyt dobrze rozumiany. Español: Venus observado por la sonda estadounidense Pioneer Venus. Português: Vénus observada pela sonda norte-americana Pioneer Venus.
context_page_description: The speculation of life currently existing on Venus decreased significantly since the early 1960s, when spacecraft began studying the planet and it became clear that its environment is extreme compared to Earth's.
  Venus' location closer to the Sun than Earth and the extreme greenhouse effect raising temperatures on the surface to nearly 735 K, and the atmospheric pressure 90 times that of Earth, make water-based life as we know it unlikely on the surface of the planet. However, a few scientists have speculated that thermoacidophilic extremophile microorganisms might exist in the temperate, acidic upper layers of the Venusian atmosphere.

  Venus' location closer to the Sun than Earth and the extreme greenhouse effect raising temperatures on the surface to nearly 735 K (462 °C; 863 °F), and the atmospheric pressure 90 times that of Earth, make water-based life as we know it unlikely on the surface of the planet. However, a few scientists have speculated that thermoacidophilic extremophile microorganisms might exist in the temperate, acidic upper layers of the Venusian atmosphere.
