Our sun cannot wake up

The sun is in a deep minimum of its activity and cannot wake up in any way. By all accounts, our luminary should already begin to gradually produce spots and flashes – signs that it comes to life after hibernation. But this does not happen, and conversations are heard louder that the ice age awaits us.

One hundred days in the sun there was not a single flash. This is a lot, even for a minimum. In the same way, the Sun was abnormally passive last year, the entire second half of 2018. Daily photographs from solar observatories show a virgin blank disk, and this is not the first year. Let's try to figure out how all this works and what it can mean.

The light that comes from the sun into your eyes right now is actually produced thousands of years ago. The fact is that the thermonuclear reaction is in the center of the sun. As a result of the reaction, photons are produced, and they begin their path to the surface through the thickness of our luminary. The sun inside is very dense. Photons are either absorbed or emitted, and it’s not the fact that forward, maybe backward, start your journey all over again, and on average, the path of a photon from the nucleus to the surface is tens of thousands, and if some kind of photon is not lucky, then and millions of years. The sun may have gone dark for a long time, but we don’t know.

Fortunately, it did not go out. Firstly, we know well stellar evolution and understand that there is still a lot of nuclear fuel inside the Sun, taking into account its age. Secondly, activity is indicated by flares (emissions of hot plasma) and spots (zones with a high magnetic field) on the surface of the body. If there are flashes and spots, then everything is in order and inside. But this is the problem.

Normally, the activity of spots and flashes for reasons not fully understood, fluctuates with a period of 11-12 years. Perhaps the Sun “swings” Jupiter with its attraction, making our star “breathe”, because the period of Jupiter’s revolution is just that. But in the cycle, failures can occur, as was the case in the 16th-18th centuries, when the Sun remained without spots for decades. No one knows the reasons for this failure. This time is called the "Small Ice Age". After all, the inactive Sun emits less energy, less heats the Earth. There was almost no summer in Europe, and winters were terribly harsh. The most famous example: they skated on the canals of Amsterdam, but today these canals do not freeze. St. Petersburg was built in the terrible cold, now there are no close frosts like the peasant builders who huddled in the dugouts. Therefore, they died in the thousands. And everyone is afraid that the Sun may throw something like that now. Only this was not enough.

Since the 1970s, the minima have become less and less, and the maxima are not as maximum as before, the activity cycle fades, as the excited tuning fork gradually stops once. And now everyone is waiting for a new cycle to begin. The sign is very simple. The spots of the new cycle do not appear at all where the spots of the old. Just by looking exactly where the spot is, you can understand whether the cycle has begun or not. So, exactly a year ago, a spot appeared, quite a small one, but it was the spot of a new cycle! And everyone rejoiced, began to congratulate each other, the sun came to life. The stain has resolved, but no new one has appeared. That is, for a year now, a new cycle cannot start. But in the spring everyone watched a colossal spot, it could be seen with a simple eye. The daredevils seized the moment when the Sun was setting, and took impressive photographs (never look at the Sun, even in the viewfinder of the camera, you will go blind!). But that was the stain from the old cycle. Old does not let go. Obviously something is broken!

What adds sinister colors to this picture is magnetic storms. Normally, they should not be in a minimum of activity. However, they are constantly happening. At the very beginning of September in Moscow, people saw the aurora – a sign of a strong magnetic storm. And this is not the first time this year. The sun manages to produce radiation streams that fly, including to the Earth and generate magnetic storms.

Not so long ago there was a storm that was not expected at all. Usually astronomers see that the plasma has come off from the external atmosphere of the Sun (corona) and flies to the Earth. This means that in a few days there will be a magnetic storm. And then nothing came off or flew, and a storm happened. Have you seen the plasma? Almost ruled out. There may be another reason. Solar radiation, it is called "solar wind", blows out of the solar system more terrible radiation, galactic. In a minimum of activity, it blows out, of course, not so much, so hard galactic rays penetrate us, which, in fact, is observed. Is this storm not caused by the Sun, but by a stream of terrible radiation, which was formed, for example, somewhere far away during the explosion of the Supernova? A bad sign, we are left, if so, without protection from galactic radiation. Rather, the sun would turn on.

Fortunately, so far many signs say that the time of the new ice age has not yet arrived. Firstly, in the XVI-XVIII centuries the sun was larger, and this was noticeable even without instruments. There is no such thing. Secondly, the sun was colder and fainter. There is no such thing either. So, if the daylight shone something and conceived, then everything is just beginning.

Naturally, you ask, what about global warming? Maybe it’s good if the Sun cools down a bit? Global warming is a very complicated and ambiguous thing. It is caused by human activity, everyone knows this, but also by the growth of volcanic activity. The planet enters a new volcanic cycle, and this is noticeable even during the life of one generation: volcanoes erupted much less in the 1950s than now. We can stop clogging nature (theoretically), but we can’t do anything with volcanoes.

Since the atmosphere is a complex machine that does not live according to the principle “they pressed a button, they got a result”, warming “everywhere” can mean a cooling “here”. For example, July turned out to be the hottest July in history, but a cold and rainy zone hung over European Russia. It’s a strange feeling when you look at the climatic map of the world: the whole planet is painted red, even Antarctica, the heat is everywhere, and from Belarus to the Urals it is cold. We poorly understand how all this works, and, of course, it would be better if one thing broke. Volcanoes are so volcanoes. Man screwed up – so man. The sun is sleeping – let the sun. But when everything happens at the same time, this is already some kind of chaos, so no one can guarantee that, in the midst of global warming, on the contrary, it will snow.
