New Horizons data hint at liquid nitrogen flows beneath Pluto's Sputnik Planitia glacier
Dark patches on Pluto's largest nitrogen-ice glacier look consistent with liquid nitrogen welling up from below, according to computer modelling. The evidence is suggestive rather than confirmed, and the source offers no direct observation of flowing liquid.
The evidence comes from dark features on Sputnik Planitia, the vast nitrogen-ice glacier New Horizons imaged. Researchers say those patches appear consistent with liquid nitrogen rising through cracks from deep beneath the ice. Their support is a computer model: it shows nitrogen could melt at the glacier's base and move upward through small conduits like a fluid. That is a modelled possibility, not a direct observation of flowing liquid. The sample here is a single body — Pluto — and one landform, so the result rests on how well the model matches conditions under the ice.
Our reading
This belongs here because it keeps a modelled mechanism separate from a measured one: nothing in the evidence is a direct detection of liquid in motion. Readers interested in how frozen worlds stay geologically active should care, and so should anyone inclined to read 'signs of' as 'found'. The idea is plausible and specific; it is not yet confirmed.
What to do or watch
Watch for work that tests the conduit explanation against other accounts of the dark features, and for any independent measurement — rather than further modelling — of liquid beneath Sputnik Planitia.
