Report: Wind, not water, formed mysterious mound on Mars

A roughly 3.5-mile high Martian mound that some scientists suspect preserves evidence of a massive lake might actually have formed as a result of the Red Planet's famously dusty atmosphere.

Jupiter's water linked to comet impact

The European Space Agency's (ESA) Herschel space observatory has solved a long-standing mystery as to the origin of water in the upper atmosphere of Jupiter, finding conclusive evidence that it was delivered by the dramatic impact of comet Shoemaker-Levy 9 in July 1994.

How to make hydrogen on the cheap

There are many challenges to achieving the dreamed-about hydrogen economy, but one of them – the ability to make hydrogen from water cheaply and at scale – could be a little closer to being overcome. If it indeed is, renewable energy could become a whole lot more economical.

How to be a moisture farmer

For human civilization to survive, people must have access to the three basics: Food, water and shelter.

3D image reveals ancient Martian flood

NASA has created a 3D reconstruction of ancient water channels below the surface of Mars, revealing evidence of a catastrophic flood in the last 500 million years.

Water vortex ties itself in a knot

Tying a smoke ring in a knot sounds impossible - but University of Chicago physicists have done something similar by creating a vortex knot for the first time, in a container of fluid.

New find of water challenges lunar formation theory

New evidence of water in moon rock samples brought back by the Apollo mission is challenging the accepted view of how the moon formed.

Ridges show evidence of Martian water

Ridges in impact craters on Mars appear to be the fossilized remnants of underground cracks through which water once flowed.

Silicon powder produces hydrogen on demand

Super-small particles of silicon react with water to produce hydrogen almost instantaneously, University at Buffalo researchers have discovered.

Treated cotton could help irrigate deserts

Researchers have developed a special treatment for cotton fabric that allows it to absorb large amounts of water from misty air and release it by itself as it warms.

Desert meteorite shows signs of wetter Mars

A meteorite found in the Moroccan desert in 2011 appears to have originated in Mars' crust - and contains much more water than any Martian meteorite ever found before.

Clays - signs of water - are 'widespread' on Mars

Clay minerals - rocks that usually form when water is present for long periods of time - cover much more of Mars than previously thought, say Georgia Institute of Technology scientists.

Gullies on Vesta may be sign of flowing water

NASA scientists have spotted long, narrow gullies on the giant asteroid Vesta that they say may have been carved out by liquid water.

Frozen water on Mercury reveals its cooler side

NASA’s Messenger spacecraft has found that water ice likely exists on the frozen poles of Mercury, the planet closest to the sun.

Mars got its water from the same place as Earth

A study of water from the Martian interior shows that Mars was originally formed from similar building blocks to Earth, but evolved differently later on.

Potentially habitable planet found practically in our back-yard

Astronomers have at last discovered a nearby Earth-like planet that could easily have liquid water - and life.

Model shows how water could flow on Mars

University of Arkansas researchers have come up with an explanation of how water on Mars could produce the flow patterns observed by NASA's Mars Reconnaissance Orbiter.

Solar wind brought water to the moon

The water found locked inside soil on the moon's surface derives from hydrogen in the solar wind - meaning there could be water on other apparently-dry bodies in the solar system too.

Martian meteorite delivers evidence of water

A meteorite that landed in the Moroccan desert 14 months ago has been traced back to Mars.

Water-mining lunar robot revealed

Carnegie Mellon University spinoff Astrobotic Technology has now completed a full-size prototype of a solar-powered robot designed to search for water ice at the moon's poles.
