What's Happening?
The last supermoon of the year, known as the 'Cold Supermoon,' was visible in the skies over the United States on December 4, 2025. This celestial event occurs when the moon is at its closest point to Earth, making it appear larger and brighter than usual.
The supermoon was observed rising behind iconic landmarks such as the U.S. Capitol in Washington, D.C., and the San Francisco-Oakland Bay Bridge. This event marked the third consecutive supermoon of the year, providing a spectacular view for skywatchers across the country.
Why It's Important?
Supermoons are significant for both scientific and cultural reasons. They offer astronomers and enthusiasts an opportunity to study the moon's surface and its effects on Earth's tides more closely. Culturally, supermoons captivate the public's imagination, drawing attention to the wonders of the night sky and fostering interest in astronomy. The visibility of the supermoon over major U.S. cities also highlights the importance of preserving dark skies and reducing light pollution to enhance the visibility of such celestial events.
