S. Cartier Probing Rare Hot Plasma Flows in the Upper Atmosphere Postmidnight flows appear to be triggered by the same mechanism that drives more frequently observed evening flows. by Sarah Stanley Optimizing Carbonate Classification on Mars Combining data from several of the Perseverance rover’s spectroscopic sensors offers a more accurate means to classify carbonate minerals that may hold hints of ancient life. by Sarah Derouin Mars Has Far Fewer Minerals Than Earth Does The development of plate tectonics and life on Earth provided avenues for mineral evolution that did not occur on Mars, resulting in relatively limited mineral diversity on the Red Planet. by Rachel Fritts Astronomers May Have Spotted the Birth of a Planet Lumps of dust are spiraling around a young star 5,000 light-years away. They could be Jupiter-like planets in the making. by Javier Barbuzano Rare Granite Body Discovered on Moon’s Farside The granite couldn’t have formed the same way that it does on Earth—with liquid water and plate tectonics. So how did it get there? by Kimberly M. S. Cartier Subsurface Oceans Could Boost Exoplanet Habitability Researchers have shown that oceans buried below layers of ice are more common than previously thought. by Javier Barbuzano Precisely Synced Clocks Pave the Way for New Science Researchers working on Hawaiian mountain tops precisely synchronized two clocks with unprecedented efficiency, demonstrating the potential to create networks of such clocks for geodesy and more. by Katherine Kornei Dramatic Flyby Confirms That Mercury’s Radioactive Aurora Touches the Ground Data collected by the BepiColombo spacecraft traces the causes of the strange aurora, which course through the planet’s weak magnetosphere. by Matt Hrodey Essential Ingredient for Life Found on Enceladus Icy plumes from Saturn’s moon Enceladus contain phosphorus, part of the biochemistry of life—the first time the element has been found in a liquid environment beyond Earth. by Matthew R.
