There was a mysterious cloud on Mars. Finally scientists realized that it was

It hangs on Mars for the third month.

Orbiter Mars Express recorded on March about 1500 km, which started to form about 20-km of the volcano Arsia Mons, near the equator of the planet, writes the Daily Mail.

At first glance, this formation looks like a volcanic eruption, but according to geological data, the last volcano on Mars died 50 million years ago.

After a detailed study, a white feather was water vapor! A water column height of 20 km was formed when strong winds hit a large hill, which hides under the frozen ice.

The ice evaporated, the steam rose up, cooled, condensed and expanded because of the low atmospheric pressure, and eventually froze in the clouds.

This is a regular phenomenon in this region, scientists believe.

"The appearance of clouds changes during the Martian day, increasing in length during the morning morning of the volcano, almost parallel to the equator, and reaches a considerable size, which can make it visible even to telescopes on Earth," said the European space Agency.

ESA scientists believe that the formation of clouds is the consequences of the global storm this summer. Beginning in late may, and by July she was completely covered by Mars and insulated the surface from sunlight.

But a huge cloud is not the only consequence of a Martian storm.

The result of the storm, NASA lost the Mars Rover Opportunity. In early June, he stopped communicating. Attempts to "Wake" it failed, he never gave "signs of life".

The Martian atmosphere is much less dense than earth's, and contains so little water that if spread on the surface of the planet, it has formed a global ocean with a thickness of 20 microns. And yet, she has clouds of water ice.

Maybe it's the Martians doing?
