Take a peek at the sky tonight and you’ll see a full moon.  A full moon is when the moon and the sun are opposite of each other from an earth perspective.

The planet Mercury will pass close to the bright star Spica in Virgo. This is a particularly good apparition of Mercury for observers in the Southern Hemisphere, less so for northerners.

The shadows of Europa and Callisto cross the face of Jupiter simultaneously, best seen from India and central Asia.
