NASA’s New Horizons spots signs of liquid nitrogen flowing on Pluto
Filed by Dr. Kai Vega
Pluto's heart is still beating. New observations from NASA's New Horizons spacecraft reveal dark streaks on the vast Sputnik Planitia glacier that look eerily like liquid nitrogen oozing up through cracks from deep below—a cryovolcanic plumbing system that rewrites everything we thought we knew about this distant dwarf planet. If computer models are right, nitrogen melts at the glacier's base and surges upward through hidden conduits, suggesting Pluto is far more geologically alive than its frozen, faraway face lets on. The outer solar system just got a whole lot weirder.

For decades, Pluto was the solar system's cosmic afterthought—a lonely ice ball at the edge of the map, named after the god of the underworld but treated more like a forgotten storage closet. Then New Horizons screamed past in 2015 and revealed a world with mountains of water ice, glaciers of nitrogen, and a heart-shaped plain that captured the world's imagination. Now, this new analysis suggests something even more astonishing: liquid nitrogen may be flowing beneath that frozen heart, rising through cracks like blood through veins.
The mechanism is deliciously weird. Sputnik Planitia is a massive glacier of nitrogen ice, but it sits on a bed that may be warm enough—just barely—to melt the ice at its base. Computer models show that this melt could then travel upward through small conduits in the ice, like
