This feature appears to be a frozen, former lake of liquid nitrogen, located in a mountain range just north of Pluto’s informally named Sputnik Planum. Captured by the New Horizons’ Long Range Reconnaissance Imager (LORRI) as the spacecraft flew past Pluto on 14 July 2015, the image shows details as small as about 430 feet (130 metres). At its widest point the possible lake appears to be about 20 miles (30 kilometres) across.
Scientists with NASA’s New Horizons mission have assembled this highest-resolution colour view of Wright Mons, one of two potential cryovolcanoes spotted on the surface of Pluto by the New Horizons spacecraft in July 2015. The feature is 90 miles across and 2.5 miles high, which would make the largest volcano in the outer solar system.
NASA’s Dawn spacecraft successfully observed Ceres at opposition on April 29, taking images from a position exactly between the Sun and Ceres’ surface. Mission specialists had carefully maneuvered Dawn into a special orbit so that the spacecraft could view Occator Crater, which contains the brightest area of Ceres, from this new perspective.
NASA’s New Horizons spacecraft made a historic New Year’s encounter with an object nicknamed Ultima Thule in the Kuiper Belt a billion miles beyond Pluto. The probe passed around 3,500 kilometres from the mysterious object at 0533 GMT on New Year’s Day, making it the most distant Solar System body ever explored up close.
