Pluto - The Dwarf Planet with a Heart-Shaped Ice Plain | NASA Imaging #3861953 (License: Personal Use)

This image shows Pluto’s diverse surface, dominated by the bright, glacially active Sputnik Planitia-a vast nitrogen-ice plain forming the left lobe of the heart-shaped Tombaugh Regio. Surrounding regions display rugged mountains of water ice, ancient cratered terrains, and dark, tholin-covered areas like Cthulhu Macula. The high-resolution mosaic was assembled from data collected during the historic 2015 flyby.

Used on astronomy, space exploration, and educational websites to illustrate Pluto’s geography, support articles about the New Horizons mission, or explain dwarf planet classification. Matches user intent for learning about Pluto’s features, mission highlights, or comparative planetary science.
