Scientists have unraveled the secret of the solar atmosphere temperature

The temperature at the surface of the Sun is about 5000 degrees Celsius, but its atmosphere is tense to millions of degrees. Scientists are trying to understand where it comes from solar energy to heat the atmosphere to such high temperatures. And, perhaps, NASA scientists have found the answer to this question.

NASA space telescope Hi-C did pictures hot solar atmosphere such high resolution, which the scientists did not exist before. Hi-C has made 165 shots of the active region of the solar corona and was able to make out details in the solar atmosphere, the size of which is only about 150 kilometers.

NASA said that it would be like to see a coin from a distance of six kilometers.

In new photographs show the magnetic loop,
are twisted around each other, like braids, and when these braids unravel occur simultaneously releases energy. These findings reinforce the theory put forward 30 years ago, that, probably, the magnetic field is the energy source that causes solar flares and coronal mass ejections.

Karel Schrijver, an astrophysicist at the Center for Advanced Technology of Lockheed Martin, said that magnetic storms manifest themselves both in space and on Earth.

"Our society is becoming increasingly dependent on space-based technologies in the field of navigation and communication, and even imagine a life without electricity we can not do. But powerful magnetic storm can cause huge problems — damage the power grid or damage the navigation system," — said the expert .

NASA astrophysicist Sertan, the Center for the Marshall Space Flight in Alabama, said that if scientists were able to predict space weather, it would reduce the negative effects of magnetic storms on the economy and society.

Sub-orbital rocket NASA telescope was launched in July last year.

Site "Survival in the wild nature", glad to see you. If you come to us, it means you want to get complete information about survival in a variety of extreme conditions, in emergency situations. Man, throughout the development, sought to preserve and protect themselves from the various negative factors surrounding it - cold, heat, hunger, dangerous animals and insects.

Site structure "Survival in the wild nature" is simple and logical, selecting a specific section, you will find information. You will find on our website recommendations and practical advice on survival, unique descriptions and pictures of animals and plants, turn-based scheme to trap wild animals, tests and reviews of travel gear, rare books on survival and wildlife. The site also has a large section devoted to video on survival survivalist-known professionals around the world.

The main theme of the site, "Survival in the wild nature" - is to be ready to be in the wild, and the ability to survive in extreme conditions.

The Survival in the wild nature - how correctly to behave, it having appeared in an emergency situation.
