OK, so the atmosphere may be blue -- but why can't the blue band in the OP's picture be "anything else".

Like I said, if you follow what you say is a band of atmosphere on the top left of Mars in the OP's image down around the the lower left hand part, then the band that you say is "atmosphere" becomes "solid planet". What happened to the atmosphere.

I think the blue band could be something else, such as glare. True, the atmosphere may be in fact contributing to the blue hue, but that blue band is too thick compared to the planet to be all atmosphere.

Even on Earth, the altitude of the atmosphere is not that high.

Those are caused by sharpening the digital images. All digital images are either sharpened inside the camera or afterward if using a raw format and doing the processing outside the camera. If you sharpen a bit to much you get the bright white pixels.

You should have listened more in class then because oxygen isn't the main component of earths atmosphere its nitrogen at 78% .

The sky appears blue to us on a clear day, because the atoms of nitrogen and oxygen in the atmosphere separate the suns white light into its many colors, and scatter them throughout the atmosphere.

The wavelength of the blue light scatters better than the rest, predominates over the other colors in the light spectrum, and makes the sky appear blue to us.

The scientific name for this phenomenon is the Tyndall effect, more commonly known as Rayleigh scattering.

well said and nicely explained
just would like to add that Mars' main athmospheric component is Carbon Dioxide at 95% according to WikiAnswers.

the pictures provided above are ashtonoshing indeed and i found a new screensaver as well



thanx for providing these photos OP!

Here is the article I got the pictures from. It is in Nowegian, but you can see what kind of telescopes and cameras have been used in the different pictures.

My favorite is the Bubble nebula.

But I also love aurora photos, here are some more taken from Norway (These were not part of the competition):

Nice pics but I think I've seen some of them before (that Mars one looks like a Hubble?) and a quick Google check only found this thread on ATS.

Here are some more pics if people are interested.

Thanks
