On Oct. 24, 2025, Robert Wagner was doing something routine: checking the quality of a map of the whole Moon, stitched together from hundreds of frames taken years apart. The software he uses turns…
Water ice leaves the same characteristic fingerprints wherever it is. Point an infrared telescope at it and it takes bites out of the sunlight it reflects: two shallow ones near 1.5 and 2.0…
NASA says a crater 728 feet across (222 meters) formed on the Moon's eastern edge sometime between April 11 and May 22, 2024. It was found only in October 2025, when an image analyst spotted it…
Venus has no moon, and a new modeling study finds that no violent event is needed to explain why: tides alone could have destroyed a satellite, if Venus ever had one. The survey is by Stephen R. Kane…
Zero longitude on Earth is a line through Greenwich. On Mars it is a small crater called Airy-0, and the line runs through it by definition. Every map coordinate on the planet, every landing ellipse,…
Two astronomers have put a number on how long the Moon's polar ice could support a city of a million people, and their answer is about a century. Martin Elvis and Jonathan C. McDowell of the Center…
In a computer, the collision that made the Moon has always been a collision between two liquids. It is not that anyone thought the young Earth and the body that struck it were molten all the way…
NASA and IBM released an open-source artificial intelligence model for studying the Moon on Sept. 10, along with a free dataset that pulls observations from nine instruments across four lunar…
Solar particles thrown out by an eruption on the Sun reached the bare surface of Mercury while the BepiColombo spacecraft flew close overhead, researchers led by the University of Helsinki report in…
Mercury's surface carries the record of how much the planet has shrunk as its interior cooled, and part of that record has been buried. G. Nishiyama of the German Aerospace Center's Institute of…
Researchers have put a ceiling on the most energetic flare the Sun could produce, and it reaches into the range of the biggest outbursts seen on other stars like it. Natalie Krivova and Emre Isik of…
A ten-sided atmospheric wave is circling Saturn's south pole, according to a paper published Sept. 2 in Science Advances by Agustín Sánchez-Lavega of the University of the Basque Country and…
