The inhabitants of the Earth believe that in the solar system they are the only living creatures. Like, only on planet Earth did the conditions for the development of living organisms form.
Of course, it is interesting to meet brothers in mind, but the interest of scientists is also fueled by the question: Are there any living conditions on any of the planets of the solar system that are similar to earthly ones?
10. Water on Mars
Data received from the radar of the European Space Agency. A reservoir of liquid water, which is covered with water ice, was discovered on the polar ice cap of the South Pole of the planet. The device fixes it for 3 years. Its length is about 20 kilometers.
The fact that water is in a liquid state suggests that a significant amount of salts are dissolved in it.
It’s very cold at the South Pole. The temperature drops below minus 68 degrees Celsius. It is obvious that at this temperature, water cannot be in a liquid state.
Such water is not suitable for drinking. But for the living of any organisms - maybe.
9. “Footprints in the sand”
Mars rover drilling rig received organic compounds in the stones of lake sediments. This is nitrogen, hydrogen, phosphorus, carbohydrate.
It turns out that there was a lake in the crater of the volcano in which life could exist. Using gas chromatography, gas compounds with traces of organic matter were detected.
8. Asteroids and comets
Comets and asteroids are fragments of matter from which the solar system formed 5 billion years ago. They used to be called "cosmic mud."
Asteroids move closer to the sun, comets away. And there are a great many of them in space. Currently, there is a hypothesis that these hermits of the universe carry living organisms or their embryos through outer space.
In addition, it is known that comets inside have a honeycomb structure, which is very convenient for transporting space water.
7. Satellite of Jupiter
The next object to study is Europe. Sixth satellite. Previously, he was observed using telescopes. Currently - from spacecraft.
Beautiful Europe is covered in ice. The surface is smooth and deep cracks are located throughout. The metal core is heated, and part of the water under the ice crust becomes liquid. The presence of microscopic creatures in it cannot be ruled out.
6. Satellite of Saturn
Tiny Enceladus is covered with a layer of ice up to 22 kilometers in depth. Under this layer, the underground ocean literally “splashes” at a depth of 40 kilometers.
Giant geysers are ejected onto the surface of the satellite, where the temperature reaches minus 200 degrees. 250 kg of steam is ejected every second. Part reaches the surface. Part goes into the outer ring of Saturn.
Water contains sodium. And its composition is similar to the water of the Earth's oceans. And if so, then potential life is more than possible.
5. Strange objects
All known life forms on Earth need the presence of water. In the Universe there are strata of this water, both in the form of cosmic ice and in a liquid state.
On the outskirts of the solar system is the Kuiper belt. It includes the icy ex-planet Pluto in conjunction with other "dwarf planets."
The radioactive processes in them emit such an amount of heat that under the surface of the planet the water is in a liquid state. At an external temperature of minus 230 degrees Celsius.
4. Surprise Titan
Saturn's satellite has a dense atmosphere. The satellite has water ice and stone. This is the only cosmic body in the Universe that contains liquid on its surface. Its peculiarity is that it is not water.
The largest sea is the Kraken. It is hydrocarbon. There are lakes of methane. There are rivers!
Simulations through computational chemistry have shown that life in liquid methane is possible. And if this postulate is put at the forefront, then research will continue further beyond the satellite.
3. Out of sight
Space satellites actually reached the edge of the solar system. Thanks to the calculated data, it is possible to simulate the probability of life in a particular corner of the Universe in experimental laboratories.
Materials are accumulating that require systematization. But there is no answer to the question whether there is a suitable place for human life in the solar system, except for the Earth.
We must look further. Outside of my galaxy. It doesn’t matter where. It is important that this be a “living planet." Located away from ionizing radiation. So that life could be born on it. And she had enough suitable water. And such a planet was found. But! To reach it, it will take several generations to live.
2. Where do aliens live?
The question, of course, is interesting. The answer is in other galaxies. Maybe, unfortunately, but maybe not, but the Milky Way is a galaxy in which the solar system is located, not the best place to live.
According to scientists, there are more populated galaxies. And there are planets in them, where the living conditions are similar to earthly ones.
1. The seeds of life
The galaxy under the fabulous name "Milky Way" was born as a result of a powerful explosion. In the solar system, life was born.
The Universe is a non-frozen system. At great distances, new stars are born and die, cosmic bodies collide with each other.
All this gives hope that as a result of such cataclysms life will be born, as on planet Earth. Scientists believe that the search for extraterrestrial life, extraterrestrial civilizations is very, very honorable.
