The moon performed a cosmic ballet with Mars this week. On Monday evening (Jan. 13), the Full Wolf Moon passed in front of Mars in what's known as a lunar occultation, during which another celestial object appears to disappear behind the moon from our vantage point on Earth.

The highlight of the week is coming tonight in the night sky - the lunar occultation of Mars. First off, at 5:27 p.m. the moon will be officially full. The full January moon is known as the "Wolf" moon.

A brightly lit Mars could be seen passing behind the full moon during a rare lunar occultation on Monday, January 13, footage captured in San Francisco shows. NASA defines an occultation as when one celestial object passes directly in front of another.
