Astronomy Picture of the Day
Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.
Explanation: A once-in-a-lifetime crater has appeared on the Moon! A comet or asteroid roughly the size of a humpback whale (approximately 10-20 meters, 30-60 feet) crashed into the Moon sometime between April and May of 2024. The Lunar Reconnaissance Orbiter (LRO), with its monthly monitoring of the Moon, captured today's images of the lunar surface before and after the event. The resulting crater, named after Apollo-era lunar scientist McGetchin, is two soccer fields across. Craters of this size are only expected once every 132 years
