Venus, Jupiter, moon shine together this weekend

Stargazers of the world are getting a treat this weekend. On Saturday and again Sunday, Venus, Jupiter and Earth's moon converge for a brilliant night show.

Venus and Jupiter already are lining up in the western sky. In mid-February, the two planets were 20 degrees apart from a viewing perspective. The gap narrows to 10 degrees by month's end.

A crescent moon joins the show this weekend for a triple combination. The celestial encounter among the three brightest objects in the night sky will be visible from around the world at twilight. The moon will appear closer to Venus on Saturday and closer to Jupiter on Sunday.

The moon then retreats from view, but Venus and Jupiter keep drawing closer. The two planets will be justthree degrees apart by mid-March.
