Image caption: NASA's Galileo spacecraft acquired its highest resolution images of Jupiter's moon Io on 3 July 1999. Io is one of the four Jovian moons discovered by Galileo Galilei in 1610. Io's colours are witness to its extensive volcanic activity as they stem from sulphuric compounds. Tidal forces from Jupiter and the neighbouring moons are the cause for Io's volcanism.

Image caption: التقطت المركبة الفضاء غاليليو التابعة لوكالة ناسا الفضائية صور عالية الدقة لقمر المشتري آيو في 3 تموز 1999. آيو هو أحد أقمار المشتري الأربعة التي اكتشفها غاليليو غاليلي سنة 1610. وتشير ألوان آيو على نشاط بركاني يمتد لمناطق شاسعة لانها تنبع من مركبات الكبريت. إن قوى المد والجزر من كوكب المشتري والأقمار المجاورة هي سبب النشاط البركاني في أيو.

Image caption: Le 3 juillet 1999, la sonde spatiale Galileo de la NASA a acquis les images à la plus haute résolution du satellite de Jupiter Io. Io est l'une des quatre lunes joviennes découvertes par Galilée en 1610. Les couleurs de Io témoignent de son importante activité volcanique, car elles proviennent de composés sulfuriques. Les forces de marée de Jupiter et des satellites voisins sont à l'origine du volcanisme de Io.

Image caption: La sonda Galileo della NASA ha acquisito le immagini a più alta risoluzione della luna di Giove Io il 3 luglio 1999. Io è una delle quattro lune gioviane, scoperte da Galileo Galilei nel 1610. I colori di Io testimoniano la sua vasta attività vulcanica, poiché derivano da composti solforici. Le forze di marea di Giove e delle lune vicine sono la causa del vulcanismo di Io.

Image caption: 美国国家航空航天局的伽利略号航天器于1999年7月3日获得了木星卫星木卫一的最高分辨率图像。木卫一是伽利略-伽利雷 1610 年发现的四颗卫星之一。木卫一的颜色源于硫化物,是大量火山活动存在的证据。木星和邻近卫星的潮汐力是木卫一火山活动的原因。
