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 Read more [...]
Magnetosphere-26 January 2013. Magnetic storm. The excitement of the magnetopause-7 — 9 to 12 points on 12-point scale. Cosmic impacts. Anomaly. The magnetosphere is tense on the one hand releases on the Sun, on the other hand cosmic waves, gravity-magnetic disturbances near and far space.
Magnetosphere, January 25, 2013. The excitement of the magnetopause-7 — 9 and 11 — 12 points on 12-point scale. Cosmic impacts. Anomaly. The magnetosphere is tense on the one hand releases on the Sun, on the other hand cosmic waves, gravity-magnetic disturbances near and far space.
Unusually large, to be similar to a shark or stingray, coronal hole time-consuming operations in the southern hemisphere of the Sun.
Space Observatory SDO photographed a huge dent on the surface of the celestial body on January 23. Coronal holes are places in the solar atmosphere where the magnetic field opens and allows the solar wind to flow into the space.Geophysicists estimate that the cloud of charged particles emanating from this "dark matter" to reach Earth orbit 26-27 January. Will it be a major blow to our planet's magnetic shell is still unknown.Because Read more [...]
A very large outbreak occurred this morning in the sun, and it is directed towards the ground. Intensity of the flash so much that Mercury shone even brighter than it was yesterday. The picture was posted only an hour, then disappeared from the site … and graphics LPI — again silent.
With the help of High Resolution Coronal Imager (Hi-C), scientists have coronal images with the highest resolution to date, according to the website NASA. Resolution made in extreme ultraviolet image was 5 times better resolution images obtained previously by other devices. Images of the solar corona (of 165 images) were made Hi-C on July 11 last year for 620 seconds. The telescope is focused on a large active region on the sun, allowing the details to consider the ever-changing structure of the solar atmosphere. The unit Hi-C 1.8 m and a mass of 210 kg is able to photograph the sun at 150 Read more [...]

The first time scientists were able to see the fine structures - so-called "spit" - in the solar corona, by which the crown is heated to millions of degrees, wrote in an article published in the journal Nature, a team of scientists who conducted the experiment suborbital Hi-C.The high temperature of the corona - the top layer of the solar atmosphere - still remained a mystery to astrophysicists. The lower layers of the Sun - the chromosphere and photosphere - heated to a temperature of tens of thousands of degrees Kelvin. In the boundary layer between the photosphere and corona thickness Read more [...]
Coronal hole in the southern hemisphere, the sun continues to rise and spewing streams of solar wind into space. This picture was taken by NASA satellites, the morning of 23 January.Coronal holes are places in the solar atmosphere, where the sun's magnetic field opens and allows the solar wind to erupt into space. The flow of solar wind flowing from this coronal hole is expected to reach Earth's orbit on January 26-27. Whether it will be a devastating blow to our planet, scientists still can not tell.Category: Sun Read more [...]
Each wave - its temperature and its material. A yellow, it seems to us, because in this range of the visible spectrum sun radiates particularly bright.Observations of the Sun at different wavelengths can accommodate the various aspects of the surface and the atmosphere. (Image NASA / SDO / Goddard Space Flight Center.)If you take a picture of the sun with a normal camera, you get a yellow featureless disk. If you do, when the light is close to the horizon, it will add a bit of red (and nothing more), because between you and the star will be more of Earth's atmosphere, the scattering waves Read more [...]
A new group of sunspots AR1678 is growing rapidly, increasing the chances of strong emissions. NOAA forecasters estimate the chance of M-flares in 55% and X-flares in 15% within the next 24 hours. Today, the sun was already two outbreaks, one of which reached the Class S8.2 according to LPI. Both outbreaks are directed toward Earth. In addition to the Solar space satellites SOHO and STEREO recorded the appearance of an unknown object of enormous size.Category: Sun Read more [...]
Astronomers NASA, working with data sets STEREO, failed to detect so-called vulkanoidov - asteroids, traded near the sun, news agencies reported. According to scientists, if there are heavenly bodies, their diameter does not exceed 5.7 km. This is the conclusion the researchers came from observations, which were conducted between December 2008 and February 2009. At this time, two identical STEREO project staff to observe the behavior of the Sun. It was assumed that during this period of time should double vulkanoidy pass near the spacecraft, but it did not. Four experts analyzed data sets Read more [...]
If you believe the data provided by the Laboratory of X-ray astronomy of the Sun, LPI - the Sun is not seen no activity and no outbreaks have reached even the class C. But the data received from the satellites SOHO and STEREO - to the contrary. There was a violent ejection.All Quiet in Baghdad?NASA well as no reports of outbreaks. It should be noted that monitoring of solar activity in recent years - is very difficult. The data comes from delays, satellite photos and SOHO STEREO simply not laid out in full.On that frame and end photos provided by NASA in the public domain, what happened next Read more [...]
Today, the sun was a powerful coronal mass ejection unknown class power and another flash according to LPI, her class was S1.0 and it is directed towards the Earth. If you look at photos from the satellites SOHO and STEREO, our planet is under constant emission in the area of which we are, and more powerful flash class is unknown, was not directed at us.Category: Sun Read more [...]

The first recorded geomagnetic storm on 16 January and continued on January 17. Unstable geomagnetic field was observed on January 18. Scientists predict geomagnetic disturbances continue on 19 and 20 January.
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.

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. Ability to find a way out from any situation: to kindle a fire, to put traps, to prepare food, to arrange dwelling and a lodging for the night; to learn to knit knots, to clear water, to be guided by districts, correctly to choose equipment, a knife. Also you can download directories to tourists, encyclopedias survivals, video Bear Grills to Survive at any cost (Man vs. Wild).
