Liquid water is an essential requirement for life on Earth because it functions as a solvent. It is capable of dissolving substances and enabling key chemical reactions in animal, plant and microbial cells. Its chemical and physical properties allow it to dissolve more substances than most other liquids.

ESA’s Herschel space observatory has shown that water expelled from the moon Enceladus forms a giant torus of water vapour around Saturn. The discovery solves a 14-year mystery by identifying the source of the water in Saturn’s upper atmosphere.

Saturn has more than 60 moons, all mostly made of water ice. Saturn’s moon Enceladus has a water-ice crust over a saltwater ocean.

While planet Saturn is an unlikely place for living things to take hold, the same is not true of some of its many moons. Satellites like Enceladus and Titan, home to internal oceans, could possibly support life.

While they look like giant discs, they’re not a solid track at all. Instead, they’re made of millions of chunks of ice, some as tiny as dust particles, others as large as buses. But if you were able to hike on one of Saturn’s outermost rings, you’ll walk about 12 million kilometers to make it around the longest one.

You probably won’t have much success walking on Saturn’s rings, unless you happen to land on one of its moons, like Methone, Pallene, or even Titan, which has been considered a potential site for a future space colony. But you’ll want to keep your space suit on, as Titan is a chilly -179.6 degrees Celsius (-292 F).

I own a Matte Grey Jupiter and I simply love that colour. Many others have found it dull and told me I should’ve gotten White or Red. But in terms of maintaining , the matte grey is probably the best , for me at least. Dust on the vehicle isn’t visible easily and neither are scratches.

Pluto’s visual apparent magnitude averages 15.1, brightening to 13.65 at perihelion. In other words, the planet has a range of colors, including pale sections of off-white and light blue, to streaks of yellow and subtle orange, to large patches of deep red.

Even through a small telescope, Saturn takes on a beautiful pale yellow with hints of orange. With a more powerful telescope, like Hubble, or images captured by NASA’s Cassini spacecraft, you can see subtle cloud layers, swirling storms mixing orange and white together.

With shimmering pinks, hues of gray and a hint of brown, a newly released image of Saturn’s rings resembles a fresco where nature is the painter. The Cassini spacecraft captured this exquisite natural color view a few days before entering orbit around Saturn.

Mercury is a silvery-white poisonous metallic element. Mercury is liquid at room temperature and used in thermometers, barometers, fluorescent lighting, batteries and in the preparation of chemical pesticides. Mercury is also sometimes called quicksilver or liquid silver.

Mercury: gray (or slightly brownish). Mercury has practically no atmosphere, so we just see the rocky surface. Note that many images of Mercury (like this one) are grayscale, derived from a single color filter.

What Color are the Planets?

• Mercury – Grey.
• Venus – Brown and grey.
• Earth – Blue, brown green and white.
• Mars – Red, brown and tan.
• Jupiter – Brown, orange and tan, with white cloud stripes.
• Saturn – Golden, brown, and blue-grey.
• Uranus – Blue-green.
• Neptune – Blue.

Explanation: Here are the true colors of planet Earth. Blue oceans dominate our world, while areas of green forest, brown mountains, tan desert, and white ice are also prominent. Oceans appear blue not only because water itself is blue but also because seawater frequently scatters light from a blue sky.
