"The temperature just wildly swings from extremely hot to extremely cold," John Monnier, a professor of astronomy at the ...

A researcher has used advanced models that indicate that the formation of Pluto and Charon may parallel that of the Earth-Moon system. Both systems include a moon that is a large fraction of the size ...

This "kiss and capture" mechanism offers a fresh perspective on planetary formation, particularly about Pluto and its largest ...

Charon is large in size relative to Pluto, and is locked in a tight orbit with the dwarf planet. A new simulation suggests how it ended up there.

These changes in appearance are the phases of the moon. As the moon orbits Earth, it cycles through eight distinct phases. The four primary phases of the moon (new moon, first quarter, full moon ...
