Titan is the only moon in the Solar System known to have a dense atmosphere, and while similar to Earth’s atmosphere in some ways, such as being rich in nitrogen, it also holds [...]

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: [...]

A landing site has now been chosen for the Rosetta spacecraft’s lander, Philae, on comet 67P/Churyumov–Gerasimenko, it was announced this morning. After several candidate landing sites had been considered, site J has now [...]

Plate Tectonics May Increase Chances for Life on Europa

Europa, with its subsurface ocean, and now evidence for plate tectonics, is a primary goal of exploration in the search for alien life. Processed image copyright: Ted Stryk. Image Credit: NASA/JPL-Caltech/Ted Stryk

Jupiter’s moon Europa is a fascinating little world, but particularly so for one reason: water. It’s deep alien ocean underneath the surface [...]

Rainfall on Titan May Create Propane Aquifers, Study Suggests

New Study Shows How Salts Could Make Liquid Water on Mars

The Phoenix lander was the first mission to land near the Martian north pole. Was it also the first to see evidence of liquid water on Mars? Image Credit: NASA/ JPL-Caltech/University of Arizona/Texas A&M University

The search for evidence of water on Mars, past or present, has been one of the driving forces behind [...]
