A new analysis of imagery collected during NASA’s New Horizons spacecraft’s 2015 encounter with Pluto provides evidence that liquid nitrogen is rising to Pluto’s surface through cracks in the northern edge of the Sputnik Planitia, part of the massive heart-shaped glacier on the dwarf planet’s surface. This is the first evidence of recently flowing liquid […]
NASA’s New Horizons Finds Evidence of Recent Liquid on Pluto’s Surface





![An educational diagram illustrating how measurement uncertainty can distort data regarding Earth's magnetosphere, featuring a detailed space visualization alongside two comparative line graphs. Top Right: Earth is shown surrounded by a complex network of blue magnetic field lines.Far Right: A bright blue, curved line denotes the "Bow shock," which transitions into an orange-red turbulent region labeled the "Magnetosheath." Spacecraft Locations: The "WIND" spacecraft is positioned far to the left in the "Solar wind" stream, connected to a label reading "Measured solar wind strength." The "THEMIS" spacecraft sits closer to Earth inside the magnetosheath, labeled "Corrected solar wind strength. Left Graph: Plots "Earth's response [mV/m]" against "Measured solar wind strength [mV/m]." A blue line initially follows a linear path but then flattens out, marked with the text "illusion of saturation due to measurement uncertainty."Right Graph: Plots "Earth's response [mV/m]" against "Corrected solar wind strength [mV/m]." A pink line continues steadily upward diagonally, labeled as the "True linear response."](https://science.nasa.gov/wp-content/uploads/2026/07/sivadas-2026-explanation-figure-v5-1.jpg?w=900)
