NASA's Opportunity rover has found veins of a mineral that appears to be gypsum, and which could only have been deposited by flowing water.
Waste water treatment could actually be increasing the amount of some toxins, by transforming common pain-killing drugs into more dangerous forms.
Liquid water on the Martian surface was probably never around for very long, meaning life would have struggled to gain a foothold there.
Astronomers have discovered an embryonic solar system surrounded by a cloud of water vapor that could eventually form comets and deliver oceans to dry worlds.
The moon may be a harsh mistress, but Russian scientists say they want to establish a colony below the lunar surface.
The Martian atmosphere contains water vapor in a supersaturated state, say surprised ESA scientists.
NASA's Mars rover Opportunity - recently arrived at the Endeavour crater - has found a rock that's different from anything it's seen before.
A team of Kentucky scientists has found a way to 'tweak' an inexpensive semiconductor to generate hydrogen from water using sunlight.
The channels on Mars widely supposed to have been created by flowing water have a completely different origin, says a Texas Tech University professor.
NASA’s Mars exploration rover has arrived at the Red Planet’s Endeavour crater which measures some 14 miles (22 kilometers) in diameter.
Renewable energy production in the United States has surpassed the production of nuclear power for the first time, a government study reports.
Recent images captured by NASA's Mars Reconnaissance Orbiter seem to indicate the presence of flowing water during the warmest months on the red planet.
ESA’s Herschel space observatory has solved the 14-year mystery of where the water in Saturn's upper atmosphere comes from - it's being expelled from the planet's moon Enceladus.
Astronomers have found an enormous cloud of water - containing 140 trillion times as much as is found on Earth - floating around a distant quasar.
Today, after a four-year journey, NASA's Dawn spacecraft will go into orbit around the asteroid Vesta, where it will stay and make observations for a year.
Two of the Air Force’s Thunderbirds aerial team members recently flew their F-16s in a Department of Defense aerial team show running on a blend of camelina-based biofuel and regular jet fuel.
The moon appears to be far richer in water than previously believed, following the discovery of 'melt inclusions' in rocks brought back from the Apollo mission in 1972.
Splitting water to create renewable energy could be simpler than previously thought, says an international team led by Australia's Monash University.
Climate change is likely to cut water flow in many of the American West's rivers by as much as a fifth, a report from the Interior Department warns. The affected rivers supply water to eight US states.
An MIT team has improved on existing systems to allow people in water-starved countries to harvest water from fog.
