The photo (released this week) says it all: an alien-looking shark, adorned with mossy hairs and a flat face, with its mouth agape and a slender bamboo shark headfirst inside.

For Valentine's Day this week, we decided to honor Mars; though the god of war, his namesake planet is all about love — at least topographically.

In 1999, the Mars Global Surveyor snapped this photograph of a "Valentine" from the Red Planet. The "heart" is actually a pit formed by a collapse within a graben, which is a geological term for a straight-walled trough which forms along fault lines. The heart-shaped pit is 1.4 miles (2.3 kilometers) across at its widest point, and sits on the slopes of the Alba Patera volcano.[See more amazing science images]
