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 was visible across the U.S. and no special equipment was necessary to view it.

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

Earth’s shadow will block most of the light that illuminates the lunar surface, creating what is known as a blood moon.
