In recent study, the Jupiter's fourth largest moon "Europa" has vast oceans and warmer weather just like the planet Earth. This indicates that there might be chances of alien life on the said planet. Likewise, the Saturn's largest moon, "Titan," may also hold alien life forms.
NASA states that Saturn's Titans in the only one with a dense atmosphere and huge liquid reservoirs on its area among the other hundreds of moons in the solar system. This makes it more like a terrestrial planet. Titan is comprised mostly of pure liquid methane and its seabed may be covered in a slush of carbon and nitrogen material. The shores of Titan may be surrounded by wetlands.
The Earth and Saturn's Titan have nitrogen-dominated atmospheres. Titan has more than 95 percent nitrogen. Earth has more oxygen yet Titan has very little oxygen. The rest of the atmosphere is mostly methane. There are also gases that include ethane.
The European Space Agency cited that methane is a by-product of the metabolism of many organisms. They explained that on Earth the simplest biological sources, such as those associated with rice fields, peat bogs and ruminant animals, continuously supply fresh gas to replace that damaged by oxidation. Then they asked if this could mean life on Titan.
