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: [...]

Buried in the Deep: Could Water Ice Deposits on the Moon Generate Their Own Organic Compounds?

A high-definition image of the Earth rising above the Moon’s south pole, taken from Japan’s Kaguya lunar orbiter in 2007. Permanently shadowed craters near the lunar polar regions have been found to harbor water ice deposits and organic compounds. Could these organics be composed in-situ inside the bottoms of these craters? Image Credit: JAXA

Messenger Spacecraft Finds Evidence of Ice on Planet Closest to Sun

Shown in red are areas of Mercury’s north polar region that are constantly in shadow in every image that the MESSENGER spacecraft has acquired to date. These areas are rich in water ice, despite the planet’s close proximity to the sun.
