While much of Perseverance's work focuses on ancient rocks that record Mars' long-lost rivers and lakes, megaripples offer a rare opportunity to examine processes that are still shaping the surface today. Megaripples are sand ripples up to 2 meters (about 6.5 feet) tall that are mainly built and modified by wind. However, when water in the atmosphere interacts with dust on the ripple surface, a

Astronomers report that starlight acting on stardust around the red giant star R Doradus cannot by itself power the strong stellar winds that spread key elements for life across the galaxy.
