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

A total lunar eclipse occurs when the Earth is positioned directly between the moon and sun, blocking the sun's rays from the moon.

The upcoming total lunar eclipse will be visible from Earth’s western hemisphere. The Moon will be right there—weather permitting—so there’s no need for special equipment to view the eclipse. For better viewing conditions, you can go to a dimly lit area to really take it in.
