During a partial lunar eclipse, Earth’s shadow appears to take a bite of the moon. The full moon is covered during a total eclipse and blushes coppery red because of stray bits of sunlight filtering through Earth’s atmosphere.

According to Dr. Angela Speck, a professor of astrophysics and department chair for physics and astronomy at The University of Texas at San Antonio, the "blood moon" total lunar eclipse will be visible across the U.S. and no special equipment will be necessary to view it.

This total lunar eclipse — the first in three years — will feature a "blood worm moon," so named for the reddish hue of its glow and the time of year it's occurring.
