Greeting the readers of the channel!
It has long been clear that there were ideal conditions for the existence of all kinds of protein life on Earth along the progress of a number of circumstances. But this is just the form that we know. Some scientists believe that there is life and on the basis of other substances, for example, silicon. Nevertheless, the known form of life requires the presence of liquid water on the planet, the source of energy as a star, which is removed to the optimal distance and the planet itself is located in the «dwelled zone», and also, other biologically useful elements.
Most recently, British scientists have discovered in the clouds of Venus GAZ FOSFIN. On Earth, this gas is produced by anaerobic bacteria. But it still’s not yet a conclusion that life on Venus is, at least in her clouds. But today we have the next question, and whether there is life on other bodies in our solar system. There are such worlds, according to scientists, and several of them.
Mars is considered as the most ideal place for life development. We give a couple of examples. The day on the red planet lasts almost like on Earth — 24.5 hours, in fact you will not notice the difference with the ground, is it that the Disk of the Sun will be less than on Earth. On Mars, as well as we — there are polar hats covered with ice and snow. And these caps are becoming less and more depending on the time of year. On the planet there is gas methane, which is most likely produced by biological processes of living beings. But this is still theory, since the source is not found. Also, the real lake was found under the southern polar shield, in which liquid water was splashing.
Nevertheless, Mars has a very subtle atmosphere, which consists of carbon dioxide, almost. This atmosphere cannot protect the surface of the planet from solar radiation and other outer radiation. The planet has a very weak magnetic field, which is why the atmosphere of Mars slowly disappears into space. There is also the same process on Earth, but our atmosphere restores its own component many times faster than it disappears into space. Thanks to the magnetic field, including. Also that water can be preserved under the surface of the planet, just as it is on Earth, when, for example, we use water in wells. So, in Mars in such water, life can be preserved.
Titan is very fascinating. This is the largest satellite Saturn. Titan is the only satellite in the solar system, which has a dense atmosphere. In Titan, many different substances and gases that can hypothetically generate or maintain life on the satellite. In Titan, there is also a methane cycle and a weather system based on it. Right like on Earth, but we are in the quality of this water. On Earth, water evaporates into high layers of the atmosphere, forms the clouds, of which the water falls on the surface. In Titan, just, but remind, there is a water — methane. These are funny things about Titan far from us. In Titan, there are rainy seasons, dry periods and, even, sand dunes on the surface created by the wind, as in the Sahara desert.
Titan’s atmosphere, consists mainly of nitrogen. Nitrogen is an essential chemical element that is used by nature to build protein life. Titanium was carefully studied on the basis of radar observation. On its surface, rivers and lakes of liquid methane and ethane were revealed. And also, cryovulkany. These are such volcanoes that mow liquid water instead of lava. All this says that titanium has a huge supply of liquid water under the surface. True, the temperature on the titanium surface is -180 ° C. It is too cold so that liquid water is on the surface. But scientists suggest that in Titans were able to form such forms of life, which fundamentally differ from their chemical composition from the earth’s protein form of life.
Europe is one of the largest satellites of Jupiter. Europe is a little less than our moon. Most likely, Europe is geologically active, as there is a strong tidal bending from Jupiter. All this heats the stony and metal inner medium, perhaps partially melted. The surface of Europe, essentially a giant space consisting of ordinary water ice, is straight a huge Antarctica on the scale of a whole satellite with the moon. Scientists believe that under the ice surface of Europe there is a huge layer of liquid water. This is an integer ocean of water whose depth is more than 100 km. This ocean of water can not freeze due to the heat of the same notorious tidal bent.
About the global ocean under the surface of Europe, scientists have come up with no just like that. This theory is confirmed by the presence of geysers that break into the surface through the ice cracks. Other factors such as a weak magnetic field are added here. Of course, the satellite has a solid stone surface under the ocean, it is so to speak. It is likely to have a chaotic surface relief, as it affects a huge pressure of water, ice and water flows at the bottom. But this ice shield isolates the booming ocean from the extreme cosmic cold and a banal vacuum. Protects the shield from radiation emanating from the Sun, the Space itself and Jupiter. Of course, at the bottom of the ocean there are hydrothermal sources and volcanoes. Let’s say on earth near underwater volcanoes contain many organic substances and a rich ecosystem, that is, there are conditions for life.
And today everything. Thank you for reading to the end.
