A total lunar eclipse will make the moon appear red across the Western Hemisphere during the "Blood Worm Moon" this week.

A.M. Friday morning the Moon will be full. This month's Full Moon is called the Full Worm Moon because traditionally this was the time of year when earthworms started to become more visible.

Stargazers on nearly one half of the world witnessed a total lunar eclipse overnight, as a rare cosmic lineup caused the moon to turn a shade of red.
