I am a native in this world And think in it as a native thinks

Astronomy Tuesday

This is a detail from a 360-degree panorama stitched together from photos taken by the Spirit Rover on Mars in 2005.

I'm always fascinated by pictures of the Martian landscape just because there's so little that's unlikely or unfamiliar about them -- this could be any desert on Earth. But I picked this particular section of the view because of what is strange to me -- the two small areas, one red and one green, in the upper right hand corner of the image.

Those are dust devils, and the colors aren't true to life; they're a result of the color filters that had to be applied to the photos to correct the general color of the landscape. But it's fun to imagine that on this rocky red-brown monochrome of a planet, at least the storms come in bright colors.
