The debate continues, but a new finding shows that its outermost moon, Hydra, is coated with nearly pure
water ice.
The spacecraft observed a dramatic geological landscape, including complex interactions between massive deposits of
water ice, methane, and frozen carbon monoxide.
With the discovery of
water ice on other planetary objects, scientists are abuzz over the probability of the presence of — and the prospect of supporting — life beyond the boundaries of planet Earth.
Water ice and perhaps liquid water occur beneath the frozen surfaces of three of Jupiter's moons, although currently none have free surface waters.
They contained
water ice, like the snow falling on Earth.
It's a crust of ice,
water ice, but below it is liquid water and it's kept liquid by the gravitational or what we call tidal action of Europa's orbit with this massive Jupiter.

Their composition is concluded to be of
water ice as it a lot less dense than the nitrogen ice carrying it away — hence they float!
The Ralph / Linear Etalon Imaging Spectral Array (LEISA) aboard New Horizons observed Pluto's surface from a range of 108,000 km to show areas where
water ice is most abundant as well as possibly detecting areas that are depleted in methane.
Scientists think that in the «heart» region of Pluto (otherwise known as Sputnik Planum),
water ice bedrock might be hidden underneath a thick blanket of other ices made of methane, nitrogen and carbon monoxide.
First discovered in 2005, the geysers of
water ice are believed to originate from a large body of water located beneath the moon's surface ice shell.
This is the first time a white dwarf with nitrogen has been discovered, and one of only a few known examples of white dwarfs that have been impacted by a rocky body that was rich in
water ice.
The reflectivity suggests that Kerberos is coated with
water ice, similar to the other small Plutonian moons.
Purpose [edit] In 2006, the Keck Observatory announced that the binary Jupiter trojan 617 Patroclus, [12] and possibly large numbers of other Jupiter trojans, are likely extinct comets and consist largely of
water ice.
Mars Odyssey spotted vast tracts of
water ice, and Mars Reconnaissance Orbiter saw «dry ice» snowflakes falling from clouds near the pole.
Water ice strongly reflects radar, and observations reveal that there are patches of very high radar reflection near the poles.
In the absence of an external atmospheric pressure, the warming of
water ice transforms it into directly into gas phase rather than liquid.
Of particular interest is a bright pit on the floor of crater Occator that exhibits probable sublimation of
water ice, producing haze clouds inside the crater that appear and disappear with a diurnal rhythm.
Europa (which is 12 percent smaller than Earth's Moon) appears to have a sparsely cratered shell of
water ice that may be only 30 to 50 million years old, and so some resurfacing process must be renewing its icy shell.
«The randomly jumbled mountains might be huge blocks of hard
water ice floating within a vast, denser, softer deposit of frozen nitrogen within the region informally named Sputnik Planum.»
It seems impossible to us today that the structure of
water ice was a mystery less than 100 years ago.
«Our measurements indicate widespread ammoniated phyllosilicates across the surface, but no detectable
water ice.
The bright white and bluish part of Europa's surface is composed mostly of
water ice, with very few non-ice materials.
Discovered in 1978 by the United States Naval Observatory, Charon is the largest of Pluto's five moons and is only half the size of Pluto and one - eighth of its mass, with a surface dominated by a mixture of
water ice and frozen ammonia.
This is an important discovery since it exposed that
water ice was considerably more widespread than what was hypothesised.
NASA's hard - digging Phoenix lander uncovered
water ice last year near the Martian North Pole.
The blue is a signature of
water ice.
The gravitational pull from these two bodies also squeezes and stretches the moon itself, and all that kneading from this tidal distortion heats Enceladus, melting some of
the water ice under the surface.
Here, bluish - white
water ice clouds hang above the Tharsis volcanoes.
Once thought to be a relatively inactive world, being so bitterly cold and far from the Sun, Pluto has been shown to be more geologically active than anticipated, with mountains of solid
water ice, canyons, unusual pits, and large, slowly moving glaciers of nitrogen, methane, and carbon monoxide ices.
False colour image of
water ice concentration across Pluto.
Most of the images from Rosetta have been in black & white, so these colour ones are a nice change and show incredible detail, including patches of
water ice on the rocky surface.
Similar to the multibillion dollar satellite industry sparked by the launch of Sputnik, Diamandis envisions this prize as opening the door to industries that utilise the Moon's resources, including silicon for large - scale solar arrays, and
water ice for oxygen and rocket fuel.
The Mars Express observations hint at greater methane concentrations over areas containing subsurface
water ice.

the water ice finding as a major discovery, but it was totally expected by the science team.
The presence of
water ice, he says, supports the idea that Saturn's superstorms are powered by condensation of water and originate deep in the atmosphere, about 200 kilometers below the visible cloud deck.
The interesting effect, he notes, is that in Saturn's massive storm, at least, the observations can be matched by having particles of mixed composition, or clouds of
water ice existing side - by - side with clouds of ammonia ice.
In addition, optical and radar images of the surface show signs of cryovolcanism — geyserlike eruptions of ammonia -
water ice — which also indicates that material wells up from the interior.
«The upper haze is so optically pretty thick that it is only in the stormy regions where the haze is penetrated by powerful updrafts that you can see evidence for the ammonia ice and
the water ice.
The key finding: cloud particles at the top of the great storm are composed of a mix of three substances:
water ice, ammonia ice, and an uncertain third constituent that is possibly ammonium hydrosulfide.
In the latter scenario,
water ice would make up 22 percent of the cloud head and ammonia ice 55 percent.
Stone's proposed venture would create rocket fuel by melting
water ice from the moon's soil, purifying it (exactly how, he says, is a trade secret), and splitting it into hydrogen and oxygen, perhaps using a solar - powered electrolysis system.
Pluto's moon Charon consists mainly of
water ice.
Pluto and most moons of the outer planets consist of rock and
water ice in varying amounts.
Its «rock» is
water ice and its rains are hydrocarbons such as methane and ethane condensed by the cold.
