It has always been difficult to describe the empty space between stars and celestial bodies between them. However, we know from evidence that among these are planets that do not exist in a star system and are free of any growing and evolving stars. These planets can have moons orbiting them to form a small, independent system. Now scientists are announcing the possibility of life in them.
According to recent mathematical models, the moons of these planets can have atmospheres and liquid water under certain conditions. These special conditions can be attributed to the cosmic rays and tidal forces on these moons under the influence of their interplanetary gravity.
Scientists find these extrasolar planets with their gravitational effects on the light of other stars. They estimate that for every star in the Milky Way galaxy, there is a brown dwarf the size of Jupiter. By that estimate, there are about 100 billion brown dwarfs in our galaxy.
On Earth, all life depends on sunlight, and even the fluidity of water depends on its heat. However, beyond the cold line of the solar system, there are places where liquid water is also found. The moons of Ganymede and Jupiter in Europe and Enceladus in Saturn are good examples. At the bottom of these moons, there is hundreds of kilometers of ice, without sunlight and only with the internal heat of the planet liquid water. Some scientists believe that microbial life may also be present in them.
With that in mind, researchers recently developed a model that suggests that some of these extrasolar planets could have moons the size of Earth with atmospheres of 90 percent carbon dioxide and 10 percent hydrogen. Liquid water is also likely to form in the environment during these months and remain stable.
Cosmic radiation can help combine carbon dioxide and hydrogen and turn them into water. Such a process can produce water 10,000 times less than on land. However, it can be enough to survive in that environment. Tidal forces can also generate enough heat to keep water liquid during these months. It can also generate enough heat to create a greenhouse effect with existing carbon dioxide. Under very favorable conditions, these planets can also contain microbial life.
