The largest newly formed crater ever discovered in the solar system has been found on the Moon, in what scientists have described as a once-in-a-century impact event.
\nThe crater, measuring 222 meters (728 feet) across and 43 meters deep, was identified using images from NASA\u2019s Lunar Reconnaissance Orbiter Camera (LROC), according to a study published in Science Advances on Wednesday.
\nResearcher Robert Wagner first spotted the feature during a routine check of images taken by LROC\u2019s Wide-Angle Camera in October 2025. Scientists then used higher-resolution observations over the following months to measure the crater and examine the surrounding terrain.
\nAccording to NASA, the crater formed between April 11 and May 22, 2024, when a comet or asteroid roughly the size of a three- to six-story building slammed into the lunar surface.<\/p>\n

The collision hurled debris across the surrounding terrain and created a \u201ccold spot\u201d about seven kilometers (four miles) wide, where nighttime temperatures are up to nine degrees Celsius (16 degrees Fahrenheit) lower than in nearby areas.<\/p>\n

Researchers believe the impact loosened, or \u201cfluffed up,\u201d the regolith \u2013 the layer of loose rock and dust covering the Moon \u2013 making it less dense and therefore less able to retain heat.<\/p>\n

Officially named McGetchin after pioneering lunar scientist Tom McGetchin, the crater dwarfs previously detected recent impacts. Before its discovery, the largest contemporary impact crater identified on the Moon measured about 70 meters across.<\/p>\n

The discovery comes as the Moon becomes an increasingly important focus of international space exploration.
\nThe US is \u201cvery much in a space race\u201d with China, NASA Administrator Jared Isaacman told CBS News in July. NASA\u2019s Artemis program is targeting 2028 for its first crewed lunar landing since the Apollo era, with the longer-term goal of establishing a sustained human presence on the Moon.
\nRussia and China, meanwhile, announced plans in 2021 to jointly develop the International Lunar Research Station.<\/p>\n

As part of the project, Russia plans to deploy a power station on the Moon within the next decade. During Chinese President Xi Jinping\u2019s visit to Moscow last May, Russia and China signed an agreement on building a nuclear power plant on the Moon to provide energy for the planned research station, which is expected to become operational in the mid-2030s.<\/p>\n","protected":false},"excerpt":{"rendered":"
