Researchers used New Horizons images to identify evidence that liquid nitrogen may have flowed from beneath Pluto’s famous heart-shaped glacier. Dark markings across part of Pluto’s enormous heart-shaped glacier may record something unexpected beneath its frozen surface: liquid nitrogen moving upward and briefly flowing across the ice. Using observations from NASA’s New Horizons spacecraft, researchers [...]
