Of Saturn’s 62 moons, the two most habitable for human life are Titan and Enceladus. They are very different from each other. For example, Titan is the second largest moon in our solar system, with a diameter of 2,575 kilometers. Tiny Enceladus has a diameter of only 500 kilometers. The atmosphere on Titan is thick and hazy, hiding surface features from most scientific instruments. Only its seasonal storms are visible. In contrast, the atmosphere on Enceladus is very thin. This means there is no air pressure or weather. However, scientists are better able to see what’s happening on its surface. Each of the moons  has a unique feature, as well. Titan is the only other place we know of in our solar system with liquids flowing across its surface. Enceladus doesn’t have liquids flowing on the surface, but there are geysers sending icy particles and water vapor into the sky at a speed of nearly 1,300 kilometers per hour.Which correct information from the text about Titan?Titan is the largest among all moons in solar system  blankTitan and Enceladus are more habitable than Saturn  blankTitan is more habitable because it has thick atmosphere and liquid on its surface  blankScientific instruments can see clearly the surface features of Titan  blank     √           Χ

Which features of Titan are unique to this moon and no other moon in the solar system?(Select All the answers that are correct)Group of answer choicesGlobal ocean beneath its icy crustIcy crustLiquid methane/ethane lakesClouds that rain methane/ethaneStable and dense planet-like atmosphere

he Earth's atmosphere is 78% nitrogen and its surface can clearly be seen from space. In comparison, Titan's atmosphere is composed of 97% nitrogen, with a small amount of methane and trace amounts of other molecules. However, the surface of Titan is obscured from view in visible light with a thick orange smog. Briefly explain what gives rise to this smog and how this is linked to the dark features observed near the north pole.

Which solar system object has an atmosphere that is most similar to Earth’s?Group of answer choicesVenusMarsEuropaTitanNeptune

Nuevas pruebas químicas sugieren que la luna de Saturno podría albergar vida. Los científicos anunciaron este año que habían encontrado fósforo en el océano de la sexta luna más grande de Saturno, Encélado. Junto con el carbono, el hidrógeno, el nitrógeno, el oxígeno y el azufre, este sexto elemento es esencial para la vida. Los astrónomos ya habían encontrado indicios de los otros cinco elementos en Encélado, por lo que este último hallazgo (detectado en granos de hielo recogidos por el Analizador de Polvo Cósmico de la nave espacial Cassini) convierte a esta roca helada en un prometedor candidato a albergar vida extraterrestre.La información objetiva del texto es:Seleccione una:a. Encédalo es una roca helada en la que se alberga vida extraterrestre.b. Los científicos encontraron fósforo en el océano de Encédalo.c. Saturno podría albergar vida gracias a los granos de hielo encontrados por Cassini.d.El carbono, el hidrógeno, el nitrógeno, el oxígeno y el azufre son los elementos esenciales para que exista vida en otros planetas.
