Jupiter's Moon lo Formed Under Unique Processes, New Study Suggests

An impressive image of Jupiter's moon Io, as seen from NASA's Galileo spacecraft from a distance of approximately 600,000 km. A volcanic eruption is easily seen at the moon's upper limb, rising almost 140 km above the surface. A new study has shown that these volcanic eruptions play an integral role in the formation of mountains on the moon's landscape as well. Image Credit: Galileo Project, JPL, NASA

New Study Suggests Mars' Ancient Surface Shifted and Tilted Due to True Polar Wander

A view of Mars showing the expansive Valles Marineris (center), which is the largest canyons system in the entire Solar System. Three of the four giant shield volcanoes that constitue the massive Tharsis region are seen at far left. A new study by an international team of planetary scientists has provided evidence that the formation of Tharsis had profound effects in the shaping of Mars' geomorphology and climate, ultimately tilting the surface by as much as 20 degrees relative to planet's axis of rotation.

NASA's Dawn Spirals to Final Science Orbit, Poised to Return Up-Close Images

From NASA/JPL: "This view, made using images taken by NASA's Dawn spacecraft, is a color-coded topographic map of Occator crater on Ceres.  Blue is the lowest elevation, and brown is the highest. The crater, which is home to the brightest spots on Ceres, is approximately 56 miles (90 kilometers wide)." Occator is home to Ceres' "bright spots." Image Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

A Deeper Understanding: Dawn Reaches Third Science Orbit, Shows Closest View of Ceres Yet

From NASA/JPL: "The Lonely Mountain The Lonely Mountain  NASA's Dawn spacecraft spotted this tall, conical mountain on Ceres from a distance of 915 miles (1,470 kilometers). The mountain, located in the southern hemisphere, stands 4 miles (6 kilometers) high. Its perimeter is sharply defined, with almost no accumulated debris at the base of the brightly streaked slope."

The Early Solar System Could Have Hosted a Fifth Giant Planet, According to New Study

Artist's impression of a rogue gas giant planet, free-floating in interstellar space. According to a new study, the early Solar System hosted a fifth gas giant planet besides Jupiter, Saturn, Uranus and Neptune, which was eventually ejected into interstellar space through the gravitational interactions with the rest of the Solar System's giant planets.
