Saturn’s largest moon Titan is one of the most Earth-like places in the Solar System, as least in terms of appearances, with its seas, lakes, and rivers […]

Stars Above and Earth Below: NASA's Proposed New Airship Competition Good for Science

Airships are a unique form of transportation—giant, balloon-like, lighter-than-air vehicles which can stay aloft for extended periods of time. Their design makes them […]

NASA's Van Allen Probes Detect Life-Protective Electron Barrier Inside Earth's Radiation Belts

A visualization of the Earth’s radiation belts, based on data that were gathered by NASA’s twin Van Allen probes. The Earth is seen to be surrounded by the plasmapause (blue-green area) and the two main radiation belts further out (multi-color area). The boundary between the plasmapause and the inner edge of the outer belt […]

Being able to find exoplanets orbiting distant stars is a major accomplishment in itself, and fine-tuning the data […]

Most of the Water In the Solar System Is Older Than the Sun, New Study Suggests

An artist’s concept of the formation process of the Solar System out of an interstellar molecular cloud and its enrichment with water. A recent study has indicated that up to half of Earth’s water is older than the Sun itself, likely originating in that cold molecular cloud that spawned our Solar System. Image credit: […]

ISEE-3 Makes Lunar Flyby, Waves 'Goodbye' Days Before Launch Anniversary
