Tilt your head to the right to "see" the frowning ghost with prominent eyes. This nighttime infrared image shows part of the region of outwash where Mawrth Vallis empties into Chryse Planitia. The dark regions are colder than the bright regions. At night rock retains heat better than dust, so the dark "eyes" are small craters with dust on the floors surrounding a rocky central peak or pit.
