NASA's New Horizons mission has detected evidence that liquid nitrogen may have recently flowed across Pluto's famous heart-shaped glacier, contrary to expectations that the distant dwarf planet would be a frozen, cratered relic. The discovery, announced in early August 2026, suggests ongoing geological activity on Pluto's surface and represents a continuation of surprising findings from the spacecraft's 2015 flyby.
- New Horizons detected evidence of recent liquid nitrogen flow across Pluto's distinctive heart-shaped glacier.
- The finding contradicts earlier expectations that Pluto would be a frozen, geologically inert world.
- Pluto continues to show signs of ongoing geological activity, including nitrogen glaciers, water ice mountains, and possible subsurface ocean.
