Nasa finds evidence that in Mars also snows

In recent months, the planet Mars is giving us news and interesting discoveries.

The arrival of the Curiosity rover to the red planet's surface has led to the covers of many media renewed interest in our neighborhood.

The new news is the confirmation of something we already sensed for some years, but what scientists had not yet achieved solid evidence.

For some time, we knew that there is ice on Mars, mostly concentrated in the planet's polar caps.

On the other hand, astrophysicists and geologists also have data that pointed to the existence of precipitation in the form of dry ice on the planet, thanks to the comments of the Phoenix Lander mission.

Now, all these assumptions and anecdotal evidence have been shaped by a study published in the journal of Geophysical research clearly indicates that the formation of a cloud of frozen carbon dioxide than 500 kilometers in diameter can produce dry ice snow.

The information sent to us the Mars Reconnaissance Orbiter (Mro) that features a full-board climate instrumental called Mars climate sounder able to analyze in great detail the features of the Martian atmosphere.

Obviously, we must keep in mind that this snow is not like we have on Earth.

The Mars atmosphere is composed of 95% carbon dioxide, which fall snowfall as ice or dry ice.

Although our planet this dry ice requires temperatures of -78 ° C to appear in solid, Mars and due to its special atmospheric conditions, it is necessary to reach -125 ° C to find this ice, something that only happens in the polar caps of Red planet.

Data sent by the Mro have attracted great interest in the scientific community because it is the first evidence of snowflakes falling on a planet outside Earth course.
