Miami (askanews) – Images surprising and exciting, leaving stunned even scientists: icy mountains that stand out on the surface of Pluto, reaching 3,500 meters above sea level. These are the first photos sent by the probe of the NASA New Horizons after his flight over a short distance of the dwarf planet. Another surprise, in the picture there are no signs of craters, despite the proximity of the planet to the Kuiper Belt, an area of asteroids and cosmic debris that constantly bombard Pluto and its five lune.La NASA said the images suggest that Pluto is geologically active and its surface contains areas geologically young, less than 100 million years, in a planet age alleged to 4.5 billion years. “We did not expect anything like that. We have established that planets very small may be active even after a long time. The subsoil on which rest these mountains must be of ice water “explain the NASA.Finora it was believed that such small bodies did not possess a sufficient amount of radioactive elements to provide the energy needed to create mountains. A theory that is belied by photos sent from the periphery of the solar system from the probe New Horizons (images AFP)
