Life in the Universe: Amazing Space Facts
Life in space is amazing by nature. Infinite space is fraught with many secrets and mysteries. Even the Sun, which shines us every day, seems to us not to be what it really is. In our article, we propose to learn some details of the device space and understand the life of our universe.
Two metal bodies in space
If two asteroids consisting of metal collide in space, there is a great likelihood of combining them into one monolithic block. This effect is called cold welding.
This does not happen on Earth, because on our planet there is an atmosphere that oxidizes iron. Invisible protection layer does not allow the iron objects to unite with each other at each contact.
You ask: why then do satellites, space ships and stations not merge into one iron mass in space? The iron from which the satellites were made was originally on Earth, where it managed to oxidize.Scientists specifically conducted research on how to make iron even more stable in space relative to each other.
Theory of the Planets
Most of us think: our solar system consists of 9 planets. The classic model looks something like this: Mercury, Venus, Earth, Mars, Saturn, Uranus, Neptune and Pluto. However, in 2006, Neptune lost its status as a planet and was classified as a dwarf planet.
The fact is that Pluto is not the only planet in the ring of asteroids with such dimensions; There are also Ceres and Xeon, Harun, Haumey, Makimaki, Varuna, Sedna, Orc and other stars who do not even have official names.
Scientists show the greatest interest in Ceres. It was discovered in 1801 as the first dwarf planet in the solar system. Moreover, it revolves around the Sun between the orbits of Mars and Jupiter.
The black hole is a sphere
People usually represent black holes in the form of a two-dimensional disk, which draws in itself all the visible objects of the Universe. Of course, there is some truth in this, but initially it was portrayed in such a way that it was easier for people to grasp the nature of the black hole.
In reality, a black hole is a sphere.Like our Sun, and all the other stars - billions of kilometers from Earth. A sphere that draws everything in, moving in its direction.
The sun is the star thanks to which life exists on our planet. But did you know such an interesting fact: The sun is yellow only because of the earth's atmosphere. But in fact it is a completely different color.
A star can emit the whole range of colors: both visible and invisible, and if you combine the whole gamut, it will give a white color. Therefore, the sun is white.
"In space, no one will hear your cry"
The title tagline of the film "Alien" says: "In space, no one will hear your cry." And this is a real fact. Sound waves cannot propagate in a vacuum; they need particles to move.
Suppose you happen to be in space in a spacesuit, yes, yes, a completely normal life situation, and your friend was also next to you, also in a spacesuit, besides radio communication does not work for you - you can lean helmets against each other communicate in a natural way, without the aid of radio or other devices, since there will be enough particles for sound to be distributed over a short distance between people.
Stars can be very strange, for example, WISE 1828 + 2650.It is remarkable because it is incredibly cold. When we say "cold", we do not mean the temperature at -20 ° C - its temperature is -127 degrees Celsius. This is the coldest star found by man in the visible part of the universe.
The next space object is BPM 37093. The name is strange, like the star itself, because its core is completely composed of diamonds. However, neutron stars are the strangest in the Universe, because they are so dense that if, say, we take the material of a star and put it on a teaspoon, it will weigh 100,000,000 tons.
Life in the universe
Many of us believe in the existence of alien life. Most likely it is. However, while there is no evidence, we cannot assert this from a scientific point of view. Despite the fact that we have not yet found life in the Universe, we have found suitable planets for the planet and called their exoplanets.
Over the entire search period, we found approximately 50 space objects. The closest one is about 10 light years from us.
If you send the Shuttle right now, while using the most advanced technology, it will fly to the planet for about 300,000 years. At the same time, it is worth considering: exoplanets have conditions for life on them, but this does not mean that it exists there.
Our space is truly diverse and uncovered, and the planets and stars present there sometimes make us think about the world order of our Universe.
