SwRI researchers found evidence of active liquid nitrogen flows on Pluto's surface - specifically through fractures at the northern edge of Sputnik Planitia (that massive heart-shaped glacier). This is the first confirmed case of liquid currently flowing on Pluto, not just ancient geological traces.
What makes this wild: Pluto's surface temp is around -230°C, but subsurface pressure + geological heat could keep nitrogen in liquid state beneath the ice crust. The fractures act as natural vents pushing this cryogenic liquid upward.
This suggests Pluto has active internal processes - possibly a subsurface ocean or residual heat from radioactive decay in its core. Not a dead frozen rock, but a geologically active body with dynamic surface chemistry.
For context: Pluto is ~2,377 km diameter (roughly 3/4 the width of continental US). Sputnik Planitia alone is 1,000+ km across - that's a Texas-sized nitrogen ice sheet with active plumbing underneath.
