Pluto's Sputnik Planitia Shows Evidence of Recent Nitrogen Seepage

New research utilizing NASA's New Horizons data indicates Pluto's Sputnik Planitia glacier exhibits signs of recent liquid nitrogen seepage. Dark streaks along the glacier's rim suggest nitrogen flowed through cracks and refroze, implying ongoing geological activity beneath Pluto's icy surface. This discovery provides insights into the dwarf planet's internal processes and potential for active "plumbing."
