Water Vapor Discovered At Ceres

ESA's Herschel space observatory has discovered water vapour around Ceres, the first unambiguous detection of water vapour around an object in the asteroid belt.

In November and December 2012 the Hubble Space Telescope maged Europa's ultraviolet emissions in the search for vapor plume activity.

Much like the Grand Canyon, Nanedi Valles snakes across the Martian surface suggesting that liquid water once crossed the landscape, according to a team of researchers who believe that molecular hydrogen made it warm enough for water to flow.

Scientists supported by NASA have detected water locked in mineral grains on the Moon. The findings hint at unknown water sources deep below the lunar surface. Data for the study came from the NASA-funded Moon Mineralogy Mapper (M3) instrument aboard the Indian Space Research Organization's Chandrayaan-1 spacecraft.

We investigate water and deuterated water chemistry in turbulent protoplanetary disks. Chemical rate equations are solved with the diffusion term, mimicking turbulent mixing in vertical direction.

Astronomers have found the shattered remains of an asteroid that contained huge amounts of water orbiting an exhausted star, or white dwarf. This suggests that the star GD 61 and its planetary system - located about 150 light years away and at the end of its life - had the potential to contain Earth-like exoplanets.

Water and Low Mass Stars

If water is the source of life, then finding the source of water certainly qualifies as a worthy astrobiological endeavor. Scientists have formulated certain scenarios for how our planet became wet and stayed wet, but other planets may not have been able to tap this same source.

Despite satellite images that show vast networks of channels, past Mars rover missions have shown limited evidence for flowing water on Mars.

The water found on the moon, like that on Earth, came from small meteorites called carbonaceous chondrites in the first 100 million years or so after the solar system formed, researchers from Brown and Case Western Reserve universities and Carnegie Institution of Washington have found.
