    Isn’t it cool? I have that one too, I show it to people and say “This is sunset on Mars!”

    Always wondered, though, why the sky looks blue? I thought that on earth, it’s Rayleigh scattering from the nitrogen atmosphere.

    My other Mars photo is a close-up that Curiosity took of the tracks it left in the dust. Billions of years of an absolutely pristine landscape, and now some tire tracks!

    @1 – The blueness is explained if you follow the NASA link under the image.

    Awesome scene. No place to raise your kids though. Cold as hell there.

    During a lunar eclipse the Moon’s getting light from the sunsets and sunrises all round the disc of the Earth. The Bad Professor [¹] wrote “[t]hat is why the Moon glows red during a lunar eclipse—not because of refracted red light from the Earth’s atmosphere, as Bill Nye and Neil Tyson would have you believe. The shadow of the Earth’s atmosphere is blue, not red.” If he thinks sunsets are blue then it’s probably a good guess that he’s a Martian.

    Thanks, @2!
    @3, I took the Bad Professor to be saying that the moon looks red during eclipses because it’s red-hot, 700 F. But, what’s the difference, with him?

    How does he know that the shadow of the earth is blue? Just asking.
    After all, all those photos from space, which might have captured the earth’s shadow somewhere, are faked.

    Maybe robots are just better at photography than humans. Better sense of art, I suppose…
