This is amazingly cool. It's a NASA Satellite Photo of a hole about the size of a football field that has been discovered on Mars.
The hold – which appears pitch black – is so deep that its insides are completely un-illuminated by the Sun and consequently so dark that nothing can be seen inside. The theory is that this is the entrance to a huge underground cave that may be capable of protecting Martian life, should such life exist.
