NASA Discovers Signs of Subsurface Liquid Nitrogen Channels on Pluto

Evidence of Underground Nitrogen Flow on Pluto

According to НВ — Техно: NASA's New Horizons spacecraft has revealed indications of possible underground channels on Pluto, where liquid nitrogen may be emerging from beneath the surface and flowing beneath the glacier. Computer simulations suggest that nitrogen ice, which can reach several kilometers in thickness, might melt under certain conditions, producing liquid nitrogen that rises through narrow conduits driven by pressure or buoyancy forces. Along the northern edge of the Sputnik Planitia glacier, dark streaks and spots have been observed, believed to result from this subsurface movement of liquid nitrogen.

The surface of Sputnik Planitia is relatively young, likely formed less than a million years ago. While scientists once thought liquid could only have existed on Pluto in its distant past, new findings allow for the possibility of liquid nitrogen existing beneath Pluto's surface today or during its recent geological history. These dark markings on the glacier’s surface provide supporting evidence for this theory.

Future Research Directions

Much of Pluto’s surface remains unphotographed in detail, and similar signs of liquid nitrogen activity have not yet been identified in other regions of the dwarf planet. Researchers acknowledge that such features might exist elsewhere, but more observations are needed to determine how widespread the subterranean movement of liquid nitrogen is on Pluto and other cold Kuiper Belt objects. These discoveries could transform our understanding of Pluto’s geological activity and evolution, emphasizing the importance of continued exploration.

The detection of potential underground liquid nitrogen channels opens new avenues for studying the geological dynamics of this distant world. These insights suggest that Pluto may still host active processes shaping its surface, challenging earlier views of its geological dormancy. Advancing our knowledge in this area will not only illuminate Pluto’s mysteries but also enhance our comprehension of other Kuiper Belt bodies, offering valuable perspectives for planetary science.
