Gallery | Cosmic Valentines | Cassini loves Rhea

We've seen several features on the Moon and Mars shaped like hearts, but this one is a little bit different; it's on Saturn's moon Rhea, a ball of ice and rock about half the size of our Moon. This Valentine feature is a few kilometers across... and what cracks me up about it is the presence of a ridge and small crater inside it, making it look as if it's winking at us!

My blog post about this.
