Moon’s Black Eye Recalls A Realm Of ‘Lost Giants’

Looking through a telescope, the moon’s countless craters are the first thing that catches the viewer’s attention.

Meanwhile the large, dark “eyes” of the Man in the Moon…

In photos taken Saturday, we see what appear to be craters on both Pluto and its largest moon, Charon. Pluto also reveals several cliffs (or are they crater walls seen in profile?) along its far limb. Colossal chasms dent the crust…

Crater-pocked Ceres Looks Back At Earth

Thought you’d like to see the latest photo of the asteroid Ceres taken by NASA’s Dawn spacecraft from a distance of 52,000 miles (83,000 km). That’s only a fifth the distance to the moon. We’re really getting clear views now of just how cratered this place is. Bright spots pop out from about the center of…
