Titã, à esquerda, está entre as maiores luas do Sistema Solar, e está perpetuamente coberta de nuvens.
Em 2005, a sonda Huygens pousou em Titã e deu à humanidade a chance de ver, pela primeira vez, sua superfície inusual.
Dione, à direita, tem menos de um quarto do diâmetro de Titã e não tem uma atmosfera significativa. A imagem, não calibrada, foi tomada em 10 de abril, após a Cassini rodear cada lua, na semana anterior.
What would it be like to see a sky with many moons? Such is the sky above Saturn. When appearing close to each other, moons will show a similar phase. A view with two of the more famous moons of Saturn in gibbous phase was captured last month by the robot spacecraft Cassini now orbiting Saturn. Titan, on the left, is among the largest moons in the Solar System and is perpetually shrouded in clouds. In 2005, the Huygens probe landed on Titan and gave humanity its first view of its unusual surface. Dione, on the right, has less than a quarter of Titan's diameter and has no significant atmosphere. The above uncalibrated image was taken on April 10 after Cassini swooped by each moon the previous week.
