Astronomers found a reservoir of ice nearest to the Sun planet


Since mercury is the closest planet to the Sun, a large part of its surface heat to very high temperatures. Moreover, a recent study showed that water in the solid state on the surface of mercury is much greater than it was assumed so far. To such conclusion experts from brown University, and the American space Agency NASA.

In the past experts have found out that ice can be found in the largest craters of mercury, the bottom of which the sunlight never reaches, and on the North pole of the planet also is constantly in the shade. However, according to the latest data, even at the bottom of small-size craters may contain some amount of ice, and even if in each individual it will be a little deepening, in General, this would mean that on mercury there is a lot of “unaccounted for” water.

In favor of the fact that small craters of mercury also contain ice, according to data collected by the scientific probe “Messenger” who was sent to the planet in 2004. Research station ceased its operation in April 2015 — consumed fuel station was broken on the surface of the nearest planet to the Sun.

Experts believe that in the three largest craters of mercury, the ice can cover an area at least 3 to 400 kilometers, and even more it is under ground on the plains surrounding these craters, and craters in four having more modest dimensions. These findings the scientists made, examining the reflectivity of the craters.

The results of the study were presented on the pages of scientific publication Geophysical Research Letters.

It is worth noting that all new deposits of ice, scientists find not only on mercury but also on another planet earth — like- Mars. In the case of the red planet, discoveries of this kind in the future may have practical significance — if one day humanity colonize Mars, or at least will send a long-term manned mission, the ability to obtain water on the spot will not deliver it in large quantities from the Ground.
