NASA's Mars Reconnaissance Orbiter has snapped a photograph of a strange hole on the Red Planet.
The hole is about 35m across and opens in to an underground cavern, one of many thought to exist below the surface. The nature of the crater surrounding the hole has been a topic of much debate, as has the cave system beneath it.
Caves on Mars are of particular interest to scientists because the relatively sheltered environment could be a good place to look for evidence of life.
What created this unusual hole in Mars? The hole was discovered by chance on images of the dusty slopes of Mars' Pavonis Mons volcano taken by the HiRISE instrument aboard the robotic Mars Reconnaissance Orbiter currently circling Mars.
