In July of 2015, the New Horizons mission made history when it conducted the first flyby in history of Pluto. In the course of conducting its flyby, the probe gathered volumes of data about Pluto’s surface, composition, atmosphere and system of moons. It also provided breathtaking images of Pluto’s “heart”, its frozen plains, mountain chains, and it’s mysterious “bladed terrain”.
These strange features showed people for the first time how radically different the surface of Pluto is from Earth and the other planets of the inner Solar System. But strangely, they also showcased how this distant world is also quite similar to Earth. For instance, in a new study, a team of researchers working on the images from the New Horizons mission noticed “dunes” on the surface of Pluto that resemble sand dunes here on Earth.
Study - Dunes - Pluto - Journal - Science
The study, titled “Dunes on Pluto“, was recently published in the journal Science. The study was led by Matthew Telfer, a Lecturer in Physical Geography from the University of Plymouth, with significant contributions provided by Eric J. R. Parteli and Jani Radebaugh – geoscientists from the University of Cologne, and Brigham Young University, respectively.
They were joined by members from the Carl Sagan Center at the SETI Institute, NASA’s Ames Research Center, the Lowell Observatory, the Southwest Research Institute (SwRI), the National Optical Astronomy Observatory, the Massachusetts Institute of Technology (MIT), the Johns Hopkins University Applied Physics Laboratory (JHUAPL), and multiple universities.
Earth - Dunes - Sand - Ridges - Desert
On Earth, dunes are formed by wind-blown sand that create repeated ridges in the desert or along beaches. Similar patterns have been observed along river beds and alluvial plains, where water deposits sediment over time. In all cases, dune-like formations are the result of solid particles being transported by a moving medium (i.e. air or water). Beyond Earth, such patterns have been observed on Mars, Titan,...
