The universe hides many interesting things.
The universe in which we live is a strange place. People do not even have studied it completely, simply because they do not have such opportunities. A large part of the currently available information is theoretical calculations of scientists. They, fortunately, are confirmed by the observations of spacecraft, but who knows what is really going on in deep space.
The interplanetary transport network. Sounds like the title of a book of science fiction writer. However, the interplanetary transport network — perhaps the most amazing phenomenon in our Universe. It is a set of paths based on the competing gravity of celestial bodies. Satellites and even spacecraft can use the transport network to navigate between objects without using energy.
Plasma. Most of us were taught in school that there are three types of matter: solid, liquid and gaseous. But there’s a fourth: plasma is the most common matter in the Universe.
The glow of the sky. A unique phenomenon that can only be seen from space. The glow comes from the energy release of the atoms and molecules high in the atmosphere. Releasing their energy gained during the day from the sun, molecules can produce visible light, oxygen, for example, gives a green.
Regulation Of The Sun. The sun alone regulates the custom kernel. When too many hydrogen atoms collide and merge occurs at too high a speed, the core heats up and slightly expands the outer layers. The extra space reduces the density of atoms and hence the frequency of collisions — the core starts to cool, triggering the reverse process.
Dark matter. One of the strangest things faced by astronomers is dark matter. This hypothetical substance from which (hypothetically) is 80% of the Universe. Scientists smash particles in the Large hadron Collider, trying to figure out whether it exists in reality.
Other worlds. Although no one mission to the nearest after-Sun star, Proxima Centauri, was not planned, it was there and should look for extraterrestrial intelligence. Unfortunately, the spacecraft will travel to Proxima Centauri as much as 74 000 earth years.
Gravitational waves. Albert Einstein reported the existence of gravitational waves in 1916, but proved his calculations only in a hundred years. The world of science was ecstatic: people realized that space-time is quite significant material value.
