New Horizons Mission Detects Evidence of Recent Liquid Nitrogen on Pluto

Analysis of imagery from NASA's New Horizons spacecraft's 2015 Pluto encounter provides the first evidence of liquid nitrogen occasionally rising to the dwarf planet's surface. This suggests recent liquid flows through cracks in the northern edge of the Sputnik Planitia glacier. The discovery, published in the Planetary Science Journal, offers new insights into Pluto's geological activity.
