A&S Physicist Sheds Light on Black Moon

Black moons occur when a second new moon rises within a single calendar month.
Different moon phases.

Walter Freeman, associate teaching professor of physics, was quoted in a Daily Mail article discussing the black moon occurring on August 25, 2025. Unlike a full moon, a new moon positions itself between the Earth and the Sun, leaving its Earth-facing side in darkness and invisible to the naked eye. When a second new moon appears within the same calendar month, it's referred to as a "black moon."

His comments were also featured in a Daily Star article.
