Scientists are continuously trying to discover a planet which will be completely habitable for life so that they can send human to that planet and colonize the planet. In order to discover habitable planet scientists studied the atmosphere of various planets and found indications of habitability on some planets and moons which are:
Until last week, life on the planet Venus was believed to be impossible, but research changed the thinking of the entire space science and related fields. In this research, researchers have found the presence of Phosphene gas in the atmosphere of Venus, which is exerted by micro-bacteria in an atmosphere where there is less oxygen.
The possibility of life on Mars is becoming the subject of a huge debate, resoans for debate:
First, yet here scientists are unanimous about that there is no life on Mars and there are no life-supporting circumstances right now.
Second, there has been a possibility of life on Mars. Yes, there is no firm evidence for this.
Third, it is not impossible to change the conditions of life on Mars.
The fourth and most important thing is that there can be the presence of life with the presence of water under the surface of Mars.
The presence of ice on the South Pole of Mars and the presence of methane in its atmosphere make Mars an interesting contender for life support. The presence of methane is believed to be a sign of biological activity there, but its true source is not known. Apart from this, the presence of carbon dioxide on Mars is also considered a positive sign.
Europa, the moon of the planet Jupiter, is geologically active. Apart from the gravity of the planet Jupiter, the influence of other moons of Jupiter also has a positive effect on it. Here, the entire surface is covered with snow, under it, the oceans of water create an environment conducive enough for life. There can be deep ecosystems of the Earth's oceans here.
Like Eupora, the moon of the planet Saturn (Enceladus) is also a snow-capped moon. Below which is liquid water. Expectations from the Enceladus were raised when astronomers found Geiger's presence at the South Pole of Enceladus. Similar activity has also been observed in the northern hemisphere of Enceladus. Like Europa, there is a possibility of life on the deep seafloor.
Titan, the largest moon of Saturn, is the only moon in our solar system where there is a permanent atmosphere. It has a seasonal system of many organic molecules as well as a special methane system like there is a seasonal system of water on the earth. There is also methane rain and dunes are also formed in dry areas like desert. Liquid water comes out of the volcanoes there. Here a different type of life can exist earlier.
The situation on the planet Venus is not favorable for the life of Earth. But the atmosphere there is very rich, there are atmospheric pressure and temperature. Although these two are very much at the moment, but this is only so in terms of human life. The discovery of the presence of phosphine has revealed a very strong possibility of micro life there.
