This site says the Martian Sky is butterscotch (yellowish brown):\n\nhttp://webexhibits.org/causesofcolor/14C.html\n\nThis page from the recent Mars rover missions say brownish grey:\n\nhttp://mars.jpl.nasa.gov/gallery/sky/PIA01547.html\n\nThe problem of calibrating the images to get a true color is not a simple one:\n\nhttp://mars.spherix.com/spie2003/SPIE_2003_Color_Paper.htm\n\nLook at pictures on the following sites:\n\nhttp://www.marsnews.com/\nhttp://marsrovers.nasa.gov/home/index.html\nhttp://mars.jpl.nasa.gov/gallery/martianterrain/PIA00563.html\n\nand they show a pinkish brown sky.\n\nAnd, Mars does indeed have a measurable atmosphere with climate changes.  It is only about 1% of that on earth but it is there and it consists mostly of carbon dioxide.  It is this atmosphere that supports dust storms on the planet and dust devils that have been imaged.\n\nhttp://mars.jpl.nasa.gov/science/climate/index.html\nhttp://seds.lpl.arizona.edu/nineplanets/nineplanets/mars.html\nhttp://marsprogram.jpl.nasa.gov/gallery/duststorms/index.html

It depends on what planets you are talking about...  Mars appears red primarily because of the makeup of the planet's surface itself...   The outer planets like Neptune appear to have the colour they do because of the atmospheric makeup (gases surrounding it)

GoogleMoon and GoogleMars - not as good as Earth, Mars is quite hi-res though - and in false colour to see elevations better. Zoom in on GoogleMoon to see great detail ;)

Because it's blue. . .\n\nWhen sunlight travels through the atmosphere, blue light scatters more than the other colors, this makes sunlight and visable sun rays a yellow-orange color. The scattered light makes the sky blue; the transmitted light makes the sunset reddish orange.\n\nBecause this scattered light is so brightly blue we cannot see through the atmposhere into space. . .only at night when there very minimal light to refract seeing as how the sun had set is on the other side of the planet!

Sunlight is made up of all the colors of the rainbow: red, orange, yellow, green, blue, and violet. Some of the sunlight is reflected off the surface of the water, reflecting the color of the sky. Some of the sunlight penetrates the water and is scattered by ripples and particles in the water (this tinges the appearance of the ocean with the color of the particles). In deep water, much of the sunlight is scattered by the oxygen in the water, and this scatters more of the blue light.

Actually it's more of a pink than red.  And it's not always red.\n\nThe red comes from all the dust suspended in the atmosphere, which comes from the severe dusts storms that are common on Mars.  The Martian "soil" is red, so when a lot of that "soil" or dust is in the air, that makes the sky look pink.  The soil is red because there's a lot of a rust-like compound in it.\n\nIf all the dust settles out of the sky, then the sky would be a pale blue color.  Blue for the same reason Earth's sky is blue.  Pale because the Martian atmosphere is very very thin.

Mars \nThe planet that is fourth outward from the Sun. Mars has a mean heliocentric distance (semimajor axis) of 1.524 astronomical units, equivalent to 141.6 × 106 mi (227.9 × 106 km). Its orbital eccentricity of 0.093, one of the largest of the major planets, causes the distance between Mars and the Sun to vary from 128 × 106 mi (207 × 106 km) at perihelion to 155 × 106 mi (249 × 106 km) at aphelion. The mean diameter of Mars is 4212 mi (6780 km), or about 53% that of the Earth. The planet has a mass of 7.08 × 1020 tons (6.42 × 1023 kg), about 11% of Earth's. The sidereal rotation period is 24h 37m 22.7s, corresponding to a mean solar day of 24h 39m 35.2s.\n\nMars appears to the unaided eye as a bright, slightly reddish star. Having a mean (synodic) period between oppositions of 780 days, Mars is in conjunction with the Sun every other year. Viewed through a telescope, Mars usually appears as a bright reddish disk marked by complex, semipermanent dark regions and variable white polar caps.\n\nInterior\n\nAccurate measurements of the planet's gravitational field made by orbiting spacecraft have shown that Mars has a dense core and thus is differentiated into a core, mantle, and crust. The crust, composed of silicate rocks, enriched in silicon and aluminum and deficient in magnesium, is believed to be about 30 mi (50 km) thick. Over geologic time, partial melting of the crust or upper mantle has caused lower-density materials to float to the surface, creating the observed lava plains and volcanic structures.\n\nAt present Mars does not have a global magnetic field of appreciable strength. However, early in its history Mars must have had a more substantial magnetic field, because its near-surface rocks exhibit strong remanent magnetism. See also Rock magnetism.\n\nGeology\n\nThe Martian surface has been modified extensively by the processes of impact cratering, volcanism, faulting, and fluvial erosion. The terrain in the southern hemisphere is very heavily cratered and thus quite old, having formed some 3.8 × 109 years ago. Much of it stands 1–2 mi (1–4 km) higher than the planet's mean radius. By contrast, the northern hemisphere is dominated by vast, lava-covered plains with relatively few impact craters and an average elevation of about 3 mi (5 km) below the mean radius.\n\nThe Tharsis rise, or bulge, is an uplifted portion of the surface that stands several kilometers above the mean elevation of the planet. Most of Mars's tectonic features are associated with Tharsis, which affects approximately one-quarter of the entire surface.\n\nThe Martian surface exhibits several enormous shield volcanoes. The largest and perhaps the youngest is Olympus Mons, which is nearly 370 mi (600 km) across at its base and stands approximately 16 mi (26 km) above the surrounding terrain. Three other large shield volcanoes, Ascraeus Mons, Pavonis Mons, and Arsia Mons, lie along the nearby Tharsis rise. In shape and structure the Martian shield volcanoes bear a strong resemblance to their Hawaiian counterparts. At the summit of each shield is a complex of calderas, collapsed craterlike features that were once vents for lava.\n\nPerhaps the most spectacular features on the Martian surface are the huge canyons located primarily in the equatorial regions. Valles Marineris, actually a system of canyons, extends for over 3000 mi (5000 km) along the equatorial belt. In places, the canyon complex is as much as 300 mi (500 km) wide and drops to more than 4 mi (6 km) below the surrounding surface. Dwarfing the Earth's Grand Canyon, Valles Marineris is comparable in size to the great East African Rift Valley. In general, the walls of the canyon are precipitous, have well-defined edges, and show evidence of slumping and landslide activity (Fig. 1).\n\n\nAn image from the Mars Global Surveyor resolves features as small as 20 ft (6 m) in a 10-km-wide portion of Coprates Chasma, which is located in the middle of Mars's vast

light green and sky blue...

Air scatters different wavelengths of light different amounts.  We normally see the sky as blue because the sky scatters higher wavelengths of light more then lower wavelengths of light.  Blue is a short wavelength while red is a long wavelength.  Anyway, when the sun is rising or setting on the horizon you are looking through much more air to see the sun then say, at noon when the sun is straight over head.  There is so much air that you see the red, instead of the blue, because the blue has long since scattered off while the red is still able to travel through the atmosphere to your eyes.

Scorpio of course!  Mars is our planet, and we rule!  Our color is Topaz. Forgot what our flower was, probably too long for me to spell anyway.  :D

The light during the day comes from our star, the sun. The sunlight has to travel through air to get to us. The sunlight looks white, but it has many colors in it (for example, a prism or a rainbow breaks the sunlight into its colors so we can see them). \n\nSome of the blue part of the sunlight cannot go through the air without getting bounced around first by the air, and so it makes it look like the blue is coming from the air in the sky instead of the sun. That is why the sky looks blue.

The atmospheric conditions are affecting the refraction of light & hence it doesn't appear to be blue today.

Night and day occur at the same time on opposite sides of a planet.

Q1) I don't understand the question.\nQ2) Enola Gay\nQ3) Bruce Graham\nQ4) Long Beach, WA USA\nQ5) Mercury\nQ5b) None\nQ6) Japan\nQ7) Light travels in wave lengths, even on a cloudless day the sky can appear orange or red depending on your persective position to the sun.  Blue is most common during mid-day because blue waves are long, and are reflected easily by the atmosphere as the shorter red and yellow waves are higher in frequency more of them get through the atmosphere.  As the sun sets sky starts to appear orange and red because you are looking through more atmosphere so almost all the blue is reflected.

Here are a few photos.  In some of the photos, I do not see any color but red, so I don't know what they are looking at, but a few have green or violet near the top of the sun.

the color of the sky depends on your mood and the way you see it.

Jupiter has many colored bands ranging from a rust color to white.  All of the colors are earthtones (browns, tans, orangish, reddish).  These colors are all found in the gaseous clouds around the core.  The color of the core is unknown as no manmade object has ever survived a descent into the atmosphere.
