Pluto’s Geological Activity Revealed
Pluto remains geologically active. Scientists have identified landslides on the dwarf planet large enough to bury an entire city. A team of geologists led by Marco Emanuele Di Scienza analyzed images captured by NASA’s New Horizons probe during its 2015 flyby and discovered six distinct landslides. These slides were located in three craters along the western edge of Sputnik Planitia.
Details of the Discovered Landslides
The largest of these events occurred in Coughlin Crater, where a mass of ice advanced 2.2 kilometers. Debris from the landslides scattered across distances ranging from 10 to over 14 kilometers. The biggest debris apron covers an area of 130 square kilometers. Two landslides were found in Giclas Crater, while three others were located in an unnamed crater.
Landslide traces have previously been observed on:
- Mars
- The asteroid Ceres
- Several icy moons of gas giants
- Pluto’s moon Charon
However, this marks the first time landslides have been found on Pluto itself, underscoring the planet’s ongoing geological activity. The research conducted by the geology team opens new avenues for studying geological processes on Pluto.
These findings suggest that Pluto hosts active geological mechanisms distinct from those seen elsewhere in the Solar System. Studying Pluto’s landslides could help scientists better understand not only its geology but also the evolution of dwarf planets in general. This may pave the way for future missions and investigations aimed at exploring this enigmatic world and similar celestial bodies.
