Rare shiny clouds spotted on Mars

(CNN) - As far as we know, Earth is a unicorn. We have yet to find a planet quite like ours. Think of what you notice on Earth each day: the shapes of clouds, how hot the sun feels on your skin, the colors of the sky when the sun sets.

Now imagine standing on the surface of Mars. When the Curiosity rover looked up recently, it captured images of clouds. The formations are rare there, but they aren't unheard of.

Observing Martian clouds can tell us more about the processes unfolding each day on the red planet -- both Earth-like and yet unknown. It's like finding out you have something in common with another person and suddenly, you understand them a little bit more.

Our corner of the cosmos remains filled with discoveries just waiting to be made.
