The Mars Reconnaissance Orbiter captured an image of a black spot that researchers think may be an entrance to a cave. Depending on how deep it goes, such a cavern could be an auspicious environment to harbor some form of life. It also might make an amenable place to set up camp for explorers.

Deep Hole Found on MarsBeyond the hole, you can look at a whole series of amazingly detailed images taken by the orbiter's High Resolution Imaging Science Experiment (HiRISE) camera, which are now available on a web site hosted by the University of Arizona.

A very dark spot on Mars could be an entrance to a deep hole or cavern, according to scientists studying imagery taken by NASA's Mars Reconnaissance Orbiter.

The hole might be the sort of place that could support life or serve as a habitat for future astronauts, researchers speculated.
