1. Enceladus

   Enceladus is the sixth-largest moon of Saturn (19th largest in the Solar System). It is about 500 kilometers (310 miles) in diameter, about a tenth of that of Saturn's largest moon, Titan. Enceladus is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System. Consequently, its surface temperature at noon only reaches −198 °C (75.1 K; −324.4 °F), far colder than a light-absorbing body would be. Despite its small size, Enceladus has a wide range of surface features, ranging from old, heavily cratered regions to young, tectonically deformed terrain. Enceladus was discovered on August 28, 1789, by William Herschel, but little was known about it until the two Voyager spacecraft, Voyager 1 and Voyager 2, flew by Saturn in 1980 and 1981. In 2005, the spacecraft Cassini started multiple close flybys of Enceladus, revealing its surface and environment in greater detail. In particular, Cassini discovered water-rich plumes venting from the south polar region. Cryovolcanoes near the south pole shoot geyser-like jets of water vapor, molecular hydrogen, other volatiles, and solid material, including sodium chloride crystals and ice particles, into space, totaling about 200 kilograms (440 pounds) per second. More than 100 geysers have been identified. Some of the water vapor falls back as "snow"; the rest escapes and supplies most of the material making up Saturn's E ring. According to NASA scientists, the plumes are similar in composition to comets. In 2014, NASA reported that Cassini had found evidence for a large south polar subsurface ocean of liquid water with a thickness of around 10 km (6 mi). The existence of Enceladus' subsurface ocean has since been mathematically modelled and replicated.These geyser observations, along with the finding of escaping internal heat and very few (if any) impact craters in the south polar region, show that Enceladus is currently geologically active. Like many other satellites in the extensive systems of the giant planets, Enceladus is trapped in an orbital resonance. Its resonance with Dione excites its orbital eccentricity, which is damped by tidal forces, tidally heating its interior and driving the geological activity.Cassini performed chemical analysis of Enceladus's plumes, finding evidence for hydrothermal activity, possibly driving complex chemistry. Ongoing research on Cassini data suggests that Enceladus's hydrothermal environment could be habitable to some of Earth's hydrothermal vent's microorganisms, and that plume-found methane could be produced by such organisms.

1. Enceladus

   Enceladus is the sixth-largest of the moons of Saturn. It was discovered in 1789 by William Herschel. Enceladus seems to have liquid water under its icy surface. Cryovolcanoes at the south pole shoot large jets of water ice particles into space. Some of this water falls back onto the moon as "snow", some of it adds to Saturn's rings, and some of it reaches Saturn. The whole of Saturn's E ring is believed to have been made from these ice particles. Because of the apparent water at or near the surface, Enceladus may be one of the best places for humans to look for extraterrestrial life. By contrast, the water thought to be on Jupiter's moon Europa is locked under a very thick layer of surface ice. Until the two Voyager spacecraft passed near it in the early 1980s very little was known about this small moon besides the identification of water ice on its surface. The Voyagers showed that the diameter of Enceladus is only 500 kilometers, about a tenth of that of Saturn's largest moon, Titan, and that it reflects almost all of the sunlight that strikes it. Voyager 1 found that Enceladus orbited in the densest part of Saturn's diffuse E ring, indicating a possible association between the two, while Voyager 2 revealed that despite the moon's small size, it had a wide range of terrains ranging from old, heavily cratered surfaces to young, tectonically deformed terrain, with some regions with surface ages as young as 100 million years old.

1. Enceladus

   one of the chief giants that revolted against Zeus, and who, as he fled and took refuge in Sicily, was transfixed by a thunderbolt, and buried under Etna. The fiery eruptions of the mountain are his breath, and the shaking of it ascribed to his shifting from one side to another. In the latter regard he serves in literature as the symbol of a blind, often impotent, struggle to throw off some oppressive incubus.

Examples of enceladus in a Sentence

1. Jay Melosh:

   So, the bottom line: If life should be found in the oceans of Europa or Enceladus, it is very likely that its indigenous rather than seeded from Earth, Mars or (especially) another solar system.

2. Linda Spilker:

   Cassini’s legacy of discoveries in the Saturn system is profound, we won’t get this close to Enceladus again with Cassini, but our travels have opened a path to the exploration of this and other ocean worlds.

3. Yasuhito Sekine:

   We knew that Mars might had liquid ocean and heat in the past, but now it's a cold and dry planet. But the Saturn moon, Enceladus, has liquid water and heat reacting to each other, which is a new discovery that raises the possibility of that there may be living organisms.

4. Hunter Waite:

   Cassini and Enceladus really allowed us to see the kind of things we could do with mass spectrometers and, more importantly, with material that's coming up straight out of the ocean, it's a way of viewing the ocean without drilling into it. We didn't necessarily have to land ; we could sit there and and sample to study quite a bit about these ocean worlds just from flying through the material that comes out of the interior. That's what the plumes are about on Europa as well. It's that connection to the interior ocean.

5. Rajani Dhingra:

   SCIENTISTS HAVE FOUND THE BUILDING BLOCKS FOR LIFE ON SATURNS MOON ENCELADUS Dhingra added that the scientific community had been in search of clouds and rains on the north pole of Titan, but had yet to see any, despite what their models suggested. People called it the curious case of missing clouds.
