10 awesome facts about the Sun that worry scientists

The sun gives us heat, energy, light, and finally life. What can we say, without our lights on Earth simply would not exist conditions for all living things. As the center of our solar system, it affects all processes of other planets. No wonder in many religions the Sun was revered as a deity and worshipped him.



The moon by night, sun day — is the pattern of our life, but the sun was not as friendly as it seems. There is a real danger, as scientists say, and many of them inevitable. Here are 10 threats that harbors our Sun.

Ultraviolet radiation

Ultraviolet radiation comes from the Sun constantly and falls on the Earth's atmosphere. If not for the ozone layer, all life would be fried on a frying pan. Human activities and other factors have depleted the Earth's ozone layer, and levels of ultraviolet radiation have increased. This radiation is to some extent useful, but the surplus for a person can result in an increase in the incidence of skin cancer, premature aging, trigger the development of cataracts and General exhaustion. As observations show, for the last 40 years, the incidence of skin cancer has increased by 15%, and this figure continues to grow.

Solar flares

A solar flare is a powerful release of intense radiation that comes from stars. Magnetic radiation waves spreads and the impact on the Ground.
But whether the influence of solar flares to the Earth as a whole? The response of scientists — no, but magnetic radiation can make the time in the Earth's atmosphere "holes" and affect many processes. Can be damaged electric devices, satellites and GPS system. Also magnetic storms can affect the health of the people. In short, solar flares bring some inconvenience, but the real damage or disaster they did not cause.

A coronal mass ejection

A coronal mass ejection (CMEs) is essentially a powerful explosion on the surface of the star, which leads to a splashing great clouds of plasma. The explosions occur in different places of the luminaries, and the mechanisms of these processes are still not well understood. Driven by the solar wind, the plasma is drawn forward. Huge mass of matter moving with a tremendous speed in space, and if on its way to be the Earth, the inevitable negative consequences. But since our planet is quite far from the Sun, coronal emissions, aimed at us happen extremely seldom.
But what damage can cause the VCR to the Earth? Scientists hasten to reassure us. Serious consequences will be, but for the modern world, stuffed with electronics, the problem will be. The more powerful the VCR, the greater the impact of its particles on the atmosphere and the Earth's geomagnetic field. They can affect the power grid, damage the appliances and even the transformers, to disrupt satellites. But while Earth is under the safe umbrella of the ozone layer, people don't have to worry very much.

Coronal holes

We know about coronal holes from textbooks on astronomy and physics. These are spots that are formed on the surface of the sun. There is a certain sequence of their education, and they are visible as dark voids.
Most often they are formed during the period of least solar activity in the eleven-year solar cycle. We see their dark spots, because these places are much colder and the rest of the surface bar top is the thinnest. There are formed voids, of which the plasma breaks away with the solar wind. This wind is very dangerous and insidious. It causes a powerful geomagnetic storms. Most geomagnetic storms we just do not notice, but a more powerful storm will be felt for susceptible people, especially with heart problems and blood pressure.
As well, the Earth is protected from solar wind by the same ozone layer. Such a beautiful natural phenomenon as Northern lights is called the solar wind that encircles the Earth at the poles. But for astronauts it is very dangerous. Powerful radiation can cause cancer and vision loss. But do not worry as for astronauts, because a whole team of experts constantly monitoring the situation and warn the astronauts about solar storms.

The strongest geomagnetic storm in history

In 1859, scientists have recorded the most powerful geomagnetic storm that ever happened in modern history. It was called a Superstorm Carrington. It came after the most powerful solar flares, causing geomagnetic disturbances at the Earth.
It seems incredible, but his power was so great that called the sunshine in those places where it should not be. In the North it was seen by residents of Honolulu, and the South saw in Chile. It is amazing and unbelievable. In those years was not so dependent of electronics, but the Telegraph said that equipment was flying sparks. There were even cases of spontaneous combustion of electrical appliances.
Scientists say that if such a storm in our time, the consequences were much more fatal. The plant would be out of order, short circuit would have caused a lot of fires everywhere. All the satellites in space would fail. There would be communication and navigation, Earth fell into darkness.
The worst thing is that such a storm could happen again. Scientists do not exclude this, but when it happens, nobody knows.

The Sun the prospects of traveling to another planet melt away

We have already talked about the dangers of solar radiation and solar wind for astronauts in space. But this radiation carries another potential problem for the inhabitants of the Earth.
Time for our planet inevitably goes and someday we will have to leave. Even after many years, but it is inevitable. But the journey to another planet may not occur due to solar and cosmic radiation.
Astronauts orbiting the Earth unable to withstand solar radiation, scientists are constantly working on it. But man is not yet able to physically move a long journey in space. It is hoped that scientists will be able to develop tools that can reliably protect people from solar radiation.

In the end, the Sun will vaporize all water stocks

Now talk about the gloomy prospects of our planet. The Sun was now at its peak. According to the star standards, our star is still young and will Shine for us for a long time. In this stable condition the Sun is about 4.5 billion years. Great news, isn't it?
But for far future generations the prospects are not good. The sun is constantly burning hydrogen converting it to helium. Because of this, every one billion years increases the brightness of the sun by about 10 percent. This seemingly small increase in brightness would bring about catastrophic consequences for the solar system and Earth. The sun will warm the Earth, it will begin to evaporate the oceans.

The oceans will boil

After the start of evaporation of the oceans, the prospects of the Land will worsen. It is assumed that water evaporation fill the Earth's atmosphere. This will cause a greenhouse effect. Will start raging circulation of water which in the end how to boil the oceans and seas. All of these cycles will lead to the almost complete drying of the surface of the Earth, and all the moisture will accumulate in the atmosphere. Although water and will be on Earth in the form of steam, to maintain a reasonable life under such conditions would be impossible. High pressure and great temperature on our home planet will destroy all the habitual forms of life. Only some bacteria are extremophiles able to survive in such conditions.

The sun will "suck" water from the Earth's atmosphere

The water is in the atmosphere, that still leaves at least some chance at life. But that too temporarily. With increasing temperature of the Sun will increase and the radiation from it. The radiation will break down the water molecules, arranging them into hydrogen and oxygen, and then they driven by the solar wind, leaving Earth's atmosphere. It will not be a quick process, but in the end, a little water will evaporate from the Earth completely.
By the way, there are several confirmed exoplanets, which are constantly losing their atmosphere under the action of the stellar wind of its light. About these and many other objects we wrote hotshot.eu.org in our article about the most beautiful planet in the Universe.

Scientists don't know how many will live to the Sun, but in the end, it will die

Have developed models, which show the demise of our Sun. Scientists argue how it happened, but that it will happen, no doubt. The main question — when?
According to the most probable models, our star will become a red giant. The core inside the Sun expand, and it will increase in size and will increase in brightness. Bloated to the size of Earth's orbit, the Sun a long time will absorb is now desolate the Earth and all other planets. Although the Earth and other planets has a chance to be thrown out of the solar system, but this planet will have to approach the Sun at a very close distance. It will happen in about 5 billion years.
Surprisingly, perhaps, our star in that distant time, maybe twice to go through the red giant stage for a few tens of millions of years. After the second significant expansion of our star, the explosion will cast the outer shell, becoming a nebula, the center of which glows white dwarf the size of our Earth. Such stars have high temperature and density. In this form, the dwarf will Shine for a few tens of billions of years, gradually extinguished.
