Summary

Description

English: Ultraviolet image of Venus's 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's clouds. The mechanism by which Venus's 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.
Čeština: Ultrafialový obrázek Venušiných mraků jak jej viděla sonda Pioneer Venus Orbiter (26. února 1979). Výrazná uskupení ve tvaru písmen C nebo Y jsou viditelná pouze v těchto vlnových délkách a sama o sobě jsou pozorovatelná krátce, nicméně opakovatelně, a jsou proto považována za stálou vlastnost mraků planety Venuše. Mechanismus absorbce ultrafialového světla těmito mraky nebyl dosud uspokojivě vysvětlen.
