Saturn's moon Enceladus, covered in snow and ice, resembles a perfectly packed snowball in this image from NASA's Cassini mission on March 10, 2012. The image was taken with the Cassini spacecraft narrow-angle camera using filters sensitive to ultraviolet, visible and infrared light. Enceladus ...
NASA has found evidence that an ice-covered moon of Saturn could sustain alien lifeDave Mosher
As Enceladus is covered in ice, it is one of the most reflective bodies in our solar system and normally looks like a bright white snowball. So to understand more about this intriguing moon, NASA analyzed data from its Cassini mission to Saturn which ended in 2017. Read more Space Our gal...
Enceladus is mostly covered in ice. Prior research has shown that the moon has a widely varied surface, including flat stretches, ridges caused by ice masses pushing against one another, and craters caused by asteroid strikes. Most recently, researchers have found that Enceladus also has a subsur...

The discovery makes Mimas even more similar to its Saturnian moon sibling,Enceladus, which scientists had already known has a subsurface ocean. Both moons exist at similar distances from the gas giant planet and are similar in size, with the ice-covered Enceladus measuring around 310 miles (500...
Saturn's moon Enceladus, covered in snow and ice, resembles a perfectly packed snowball in this image from NASA's Cassini mission released on Dec. 23, 2013. This view was taken by Cassini on March 10, 2012. It shows the leading side of Enceladus. North on Enceladus is up and rotated ...
Titan—the giant planet Saturn’s largest moon—is the second largest moon in the solar system, outranked only by Jupiter’s moon Ganymede. Titan’s diameter of 5150 km makes it bigger than Mercury and only 25% smaller than Mars. Titan is small compared to Earth, with a surface gravity ...
Saturn, a gas giant like Jupiter, is covered with a thick atmosphere composed mainly of hydrogen and helium, with some methane and ammonia; its temperature is believed to be about −270℉ (−168℃), suggesting that the ammonia is in the form of ice crystals that constitute the clouds....
