Where did the water on Earth?

Extensive before that scientists began to wonder about the origin of water on Earth . And so far the official maintained that the volatile elements (such as hydrogen, nitrogen or carbon), and even the first organic matter, arrived here from abroad , contributed by comets and meteorites by class of origin very old, the carbonaceous concretes . Both classes of objects are formed beyond the orbit of Jupiter and "migrated" then into the Solar System.

Surprise! Mars is full of water

According to an article just published in the journal Geology, there is strong evidence indicating the existence of vast underground reserves of water on Mars. The finding, which has come as quite a surprise, it reinforces the idea that the Red Planet can, or could at some point, support life. And it increases the chances of establishing human colonies there in the near future.

The issue of "Martian water" has been debated for more than a century. First, the late nineteenth century, were the famous canals of Mars. Later, in full space age, came the discovery of ancient river valleys and sea revealing a past Martian water-rich surface.

A radioactive cesium textile absorb the water and soil

Researchers from the Institute of Industrial Science, University of Tokyo (Japan), have fabricated a fabric that absorbs radioactive cesium content in the water and soil. According to experts, this creation may be useful in the cleansing efforts in areas affected by radiation in Japan.

According to Nippon newspaper has published the 'Mainichi Shimbun', the experiment was conducted in a village in the province of Fukushima, where the nuclear plant badly damaged by the earthquake of March 11, 2011.

A cosmic collision might fade away the water

A cosmic impact might have been the cause of a temporary warming of Mars and, therefore, the disappearance of water on its surface, according to a study published in international 'Astrobiology Magazine. Experts have said that this discovery could help explain how a planet so cold and dry ever could contain liquid water and potentially favorable conditions for life.

The Earth: A water planet?

The Earth is the planet of our solar system where almost 70% of it is covered by water that makes up the oceans. This is due to the combination of the profusion of the chemical in the solar system, hydrogen, which is the most abundant element in the universe and oxygen, one of the most common in nuclear reactions that occur within the stars. To this is added that the atmosphere created in the surface conditions temperature and pressure close to the triple point of water,
