Are there water in any other planets?

Answer 1

"Water ice" and "water vapor" can be found on some of the terrestrial planets and satellites in our Solar System. Liquid surface water is currently only found on the Earth, although evidence for ancient seas and channels exist on Mars. Data from the Galileo mission suggest a layer of liquid water may exist beneath the icy surface of Europa, one of Jupiter's satellites.☺

Answer 2

There isnt any water that we know off in other planets other than Earth, but there are other bodies in the solar system that scientist believe contain water. One such body which is beyond any doubt is a moon of Jupiter known as Europa.

Europa is unlike any other body in the solar system, it is not jupiters smallest moon rather the smallest of the galilean moons of jupiter with a diameter of 3100km. Its surface is among the brightest in the solar system, a consequence of sunlight reflecting off a relatively young icy crust. Its face is also among the smoothest, lacking the heavily cratered appearance characteristic of Callisto and Ganymede. Lines and cracks wrap the exterior. if you were to scale Europa down it would probably be a smooth as a billiard ball. Scientists believe that beneath Europa's icy surface lies a liquid ocean which has the possibility of harbouring life. Let me make myself clear, we're not talking about intelligent life, but rather life that could be very similar to what is found at the bottom of our oceans.

Europa has a very tenuous atmosphere which is mostly made up of oxygen. Unlike oxygen on Earth however, which is created as a byproduct of photosynthesis in plants, oxygen on Europa is likely to originate when charged particles from the Sun hit water molecules on Europa’s surface. The water molecules are broken into hydrogen and oxygen atoms, and sometimes recombine to form hydrogen and oxygen gas.

NASA is planning to send a probe to Europa hopefully in 2015. This probe will land and have a device that will either melt or drill its way through the ice layer which could be a extensive a 10 to 15km. Once through the probe will launch a second probe which will act as a submarine and explore Europa's oceans. The Galileo spacecraft which arrived at Jupiter in 1994 confirmed that there is a liquid, briny ocean at some depth below Europa’s surface. It would also be an environment in which primitive unicellular organisms, called extremophiles on Earth, might be able to survive. As a result, any mission planned to land on Europa will have to pass extremely strict “planetary protection” qualifications in order to prevent the contamination of Europa by Earth organisms.

As a marine scientist and a person with a huge passion for astronomy, Europa is one of the most exciting bodies in the solar system. The things that could be learnt from this moon are endless and scientist are very eigar to try and draw comparisons to the earths oceans, but if there one thing the universe has taught us is to always expect the unexpected.

Answer 3

Tantalising signs of water have been found in the atmospheres of planets orbiting distant stars. If the discovery is confirmed, it will fuel speculation that the Galaxy is teeming with life.

"This would be a historic discovery - the first detection of a prebiotic molecule in an extrasolar planet," says Cristiano Cosmovici of the Institute for Cosmic and Planetary Sciences in Rome, whose team made the discovery.

One of the planetary systems orbits the star Upsilon Andromedae, about 50 light years away. There are three planets in this system, with minimum masses of about 0.7, 2.1 and 4.6 times the mass of Jupiter. They are all gas giants like Jupiter, although it is possible that the system could also contain undetected rocky planets like Earth.

There are also signs of water near two much closer stars: Epsilon Eridani, a Sun-like star 10 light years away, and Lalande 21185, a red dwarf about 8 light years away. Between them they may have three planets with a similar mass to Jupiter, but the evidence is weaker than for Upsilon Andromedae's planets.

A recent article in Science magazine spoke of radar evidence
for frozen water at the north pole of Mercury. Ice may also be present at the
smaller south pole. There is good evidence that Venus has some small amount
of water vapor in its atmosphere. All of the gas giants(Jupiter, Saturn,
etc.) likely have water ice as a significant component of their cores, and
Voyager found that Jupiter's and Saturn's atmospheres have frozen water
clouds, and below them clouds of liquid water droplets. Ice is the major
constituent of Saturn's rings, and is a major component of the crust and
mantle of several of Jupiter's and Saturn's moons (indeed, there is
speculation that Jupiter's moon Europa, in addition to having a crust that is
largely ice, may have a layer of liquid water beneath this crust.)

Answer 4

All the comets are largerly made up of ICE and dust only.. and as far as planets are considered, some of them have polar ice caps like mars. and some satellites of jupiter ans saturn have water ni the form of ice.. never have i come across water in the liquid form.

Answer 5

Sure. Water appear in other rock planet but it was change to gases because of the unrightly position to gain the solar energy.

Answer 6

I don't think so. Because the formula of water is H2O(hydrogenn , 2 of oxygen).As we know there is no life supporting gas called oxygen then how will water be formed.It needs 1 atom of hydroge and 2 atoms of oxygen and when an electric current is passed through it new substance called water is formed.

Answer 7

Comets are believed to contain water ice, so it is resonable to suppose that other planets also have water ice

Answer 8

Its is supposed to be water under the soilof Mars and under the surface of the moon.

Answer 9

there is a possibility , that among the plants some contains water in the surface.
most amazing is, EUROPA may consists of water.

Answer 10

Hi,

yes, when nasa sent its shuttle on mars evidences of water have been found. And it also said that life is possible on mars.

byeeee.
