These images are from the new Unified Geologic Map of the Moon, the most detailed lunar map ever created. Just released by the U.S. Geological Survey, it melds data from last century’s Apollo mission era with fresh information captured by NASA’s Lunar Reconnaissance Orbiter and the Japanese Aerospace Exploration Agency’s SELENE lunar orbiter. From Science […]
While scientists have studied Moon rocks for 50 years, researchers have for the first time conducted deep analysis on a single grain of lunar dust, atom by atom. Using a common materials science technique called atom probe tomography that’s not widely used by geologists, the Chicago Field Museum’s Jennika Greer and colleagues probed the grain […]
Described by their finder as “Yoopalite” rocks, a cache of fluorescent sodalite-laced stones was found on a Michigan beach. The apparently bland, well-weathered pebbles light up under 365nm; agate-hunter Erik Rintamaki discovered them in 2017 while experimenting with ways to reveal the rare stones. I actually sold a few to at Michigan Tech University, and […]
