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.

During the early morning hours, the Earth passed between the sun and moon, casting a shadow over the moon for a total lunar eclipse.

Pictures of last night's "Blood Worm Moon," a total lunar eclipse, show the full moon looking red in the night sky.
