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

Carbon Worlds May Be Waterless, Finds NASA Study

This artist’s concept illustrates the fate of two different planets: the one on the left is similar to Earth, made up largely of silicate-based rocks with oceans coating its surface. The one on the right is rich in carbon — and dry. Chances are low that life as we know it, which requires liquid […]

The Space Race, one of many fronts of the Cold War, began in earnest on July 29, 1955, when President Eisenhower publicly announced Project Vanguard, the first genuine effort to launch a man-made vehicle into orbit as an instrumented scientific experiment for the International Geophysical Year. Bypassing Werner Von Braun’s more […]
