Ganymede may be "club sandwich" moon

By - May 2, 2014 2 Pictures
In a combination of the astronomical and the culinary, scientists at NASA’s Jet Propulsion Laboratory (JPL) say that Jupiter’s largest moon, Ganymede, may not have a single large ocean, but instead may be built like a club sandwich with alternating layers of ice and water. The claim is based on computer models of how salt water acts under the high pressures that may exist beneath Ganymede’s global ice pack, and may improve the chances of finding life elsewhere in the Solar System.

Alpha Centauri B may have "superhabitable" worlds

By - January 27, 2014 10 Pictures
Since Earth is the only known inhabited planet and we happen to live here, it’s only natural to regard it as the ideal place for life to exist, and to assume that another life-bearing planet would be fairly similar. However, that is not the opinion of scientists René Heller and John Armstrong who contend that there might be a planet even more suitable for life than Earth 4.3 light years away orbiting the star Alpha Centauri B.

Is Ceres an oasis between Mars and Jupiter?

By - January 27, 2014 7 Pictures
In mid-2015, the asteroid probe Dawn is scheduled to establish orbit around Ceres, the only dwarf planet in the inner Solar System, as well as the largest asteroid, to begin roughly six months of close-up observation. The level of interest in this mission has significantly increased with the detection by the ESA's Herschel space observatory of plumes of water vapor being exuded from Ceres' surface from a pair of local sources.

NASA's NEOWISE discovers its first new near-Earth asteroid since returning to work

By - January 8, 2014 4 Pictures
NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) may have only come back online last September after a 31-month hibernation, but it’s already producing results. According to the space agency, the unmanned spacecraft discovered a never-before-seen asteroid on December 29 – the first discovery of its new mission to seek out potentially hazardous near-Earth objects (NEOs).

NEOWISE returns first test images post hibernation

By - December 29, 2013 7 Pictures
NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) has sent back the first test images from its 16-in (40-cm) telescope and infrared cameras as it is prepared for its new mission. Intended to seek out potentially dangerous asteroids and help in selecting a near-Earth object as part of the space agency’s asteroid retrieval effort, NASA says NEOWISE will be a powerful tool for discovering, cataloging and understanding the asteroids in the inner Solar System.

GRAIL mission casts new light on the "Man in the Moon"

By - November 12, 2013 4 Pictures
Sometimes great mysteries hang right over our heads. We’re so used to looking up and seeing the “Man in the Moon” that we often don’t realize that those familiar dark areas on the face of our nearest neighbor are part of a centuries old question that has yet to be answered. Many hypotheses have been put forward and now data from NASA's twin Gravity Recovery and Interior Laboratory (GRAIL) lunar orbiters has provided new insights into how the surface of the Moon formed and how its distinctive “seas” came to be.
