Star chart gift

Stars are not only a beautiful glow and a landmark in the night sky, they are also the basis of any life. This confirms still only one heavenly body is our Sun, but it makes sure, every day bringing us light and heat for millions of years. But what interesting facts about the stars we still know? By the way here is star chart gift.

1. All stars, no matter how different they are, always consist of the same matter. In their initial state, 74% is hydrogen, 25% goes under helium, and 1% are gaseous impurities of various kinds. Throughout its existence, the stars are gradually processed hydrogen and the example of the Sun, in which this ratio is already 70% to 29%, to observe this process is most convenient.

2. Among the interesting facts about stars in space is the balance of their processes. In fact, gravity causes the celestial body to be drawn into itself, significantly decreasing in size, and this could last millions of years, until in volume they would not all look like neutron stars, if not for light. Due to the constant thermonuclear reaction, it is produced and comes from the very center of the sun, passing through it for thousands of years, acting as a resistance to gravity.

3. The largest number of stars is occupied by red dwarfs. They are usually half the size of our Sun and produce a correspondingly small amount of energy – about 0.00001 of the capabilities of our sun. They are called failed, defective and the internal supply of hydrogen is only enough for 10 trillion years.

4. Interesting fact about the stars in the sky. We used to think that blue glow is cold, and orange and red light in turn are more like heat sources. But in fact, it is the fiery red luminaries have a minimum temperature – no more than 3,600 Kelvin, and blue maximum – up to 12,000 Kelvin.

5. At first glance, it seems that each star in itself. But there are those that form pairs, while having a common gravitational center. But this is not the limit, scientists have found three and four celestial bodies connected in one system. One has only to imagine that instead of one Sun we could have four.

6. The biggest planet in our system is Saturn, it is truly huge, but there are stars that could absorb it. They are called supergiants and one of the most famous is Betelgeuse, it is 1000 times larger than our Sun. However, this is not the limit, because the most of the huge considered to be VY Canis major, which is twice that of Betelgeuse.

7. An interesting fact about planets and stars, if instead of our Sun was something a little hotter, a few million years mercury would have just turned into steam.

8. Small heavenly bodies end their existence, forming white dwarfs, and giants in turn leave after themselves black holes.

9. Despite the incredible number of gaseous giants that surround us, they are all very, very far away. The nearest one is Proxima Centauri, about four and a half light-years from Earth. That is, a ray of light will be able to overcome this distance in such a time, as for a person, then on the most incredibly fast spacecraft it would take at least 70 thousand years, which makes traveling between the luminaries simply impossible at the moment.

10. How many stars are there? To calculate this is extremely difficult, and maybe even impossible, because only in our galaxy their number is on average 300 billion. And there can be 500 billion galaxies in total, and each has about the same number of gaseous giants, which makes the total number quite frightening.
