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

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.

As the Full Worm Moon rose overnight, skywatchers across the Americas turned their eyes — and their cameras — toward the sky. Over several hours, Earth's shadow slowly crept across the lunar surface, turning our celestial neighbor into a deep, blood-red orb.
