Following the first exploration of the Pluto system in history, NASA’s New Horizons team have published their first research paper detailing their findings of the distant planet.
The paper, entitled “The Pluto System: Initial Results from its Exploration by New Horizons,” describes an unusual heart-shaped region, intriguing moons, and a surprising degree of diversity and complexity in the Pluto System.
Team members believe that some of the processes on Pluto have occurred relatively recently, including those which involve the water-ice rich crust that they have discovered. This raises fundamental questions about how small planets remain active billions of years after their formation.
NASA’s New Horizons spacecraft made it to within 7,750 miles of Pluto’s surface at its point of closest approach, gathering so much data that scientists won’t see the extent of it for another year.
Jim Green, director of planetary science at NASA Headquarters in Washington, describes the mission as only the beginning. “The New Horizons mission completes our initial reconnaissance of the solar system, giving humanity our first look at this fascinating world and its system of moons. New Horizons is not only writing the textbook on the Pluto system, it’s serving to inspire current and future generations to keep exploring — to keep searching for what’s beyond the next hill.”
