We are not yet able to get a glimpse of such exoplanet where life is present. This is because it is possible that the planets that we are considering as lifeless, should go into the earth in future.
Solar System (Nasa)
The day when mankind captures a blurry picture of another world present in a corner of the universe, evidence of life is found there, it will be a big discovery. This discovery will change the entire history of mankind and our position in the universe will also change. There has been an attempt to find such planets for a long time. Some such planets have also been identified, but whether there exists life, there is no evidence yet. These planets are named as ‘Prithvi 2.0’ and ‘Earth’s twin brothers’.
However, we are not yet able to get a glimpse of such exoplanet where life is present. This is because it is possible that the planets that we are considering as lifeless, should go into the earth in future. Significantly, millions of years ago, the Earth was like such planets. Explain that exoplanets are those planets, orbiting a star like the Earth. There is presence of water and cloud on these planets. In addition, they are located in the Habitable Zone of their solar system.
If we got a life beyond our knowledge, would we consider it a life?
Giada Arne, an astronomer and astronomer at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, said that planets that are thought to be Earth-like may be completely separate from the present-day Earth. He said, Suppose there exists such a life, which we do not even consider life. In such a situation, will we recognize life as if we do not know it? In this way, the biggest question arises, which we have been asking for centuries. Are we alone in this universe?
Time determines life on the planets
When we look for another planet like Earth, we have to understand the phase of development of planets. There may also be a rocky planet, on which life has just started to flourish, but its atmosphere is in the grip of orange dust. Just like the millions of years old earth. Our earth was not worth living for millions of years. We have found many such planets till now, which are somewhat similar, where the temperature is either very high or very cold. In such a situation, it can also be believed that there may be life on these planets in the coming times. But how long it will take, no one can tell right now.
Some chance of life on these planets
It is said about Mars that once upon a time it must have been a hot and humid planet, on which life would be present. But now it is dry, cold and lifeless. In addition, the Europa Moon of Jupiter is also seen as a satellite with potential life. Life is believed to exist beneath its icy surface. The same thing is said about the Enceladus moon of Saturn. Evidence of the existence of life is also seen on another moon Titan of Saturn, because there is evidence of lakes and rivers. But instead of water in rivers, a mixture of methane and ethane flows.
Four thousand exoplanet discovered so far
Scientists have confirmed the presence of 4000 exoplanets in our galaxy. Most of these planets are rock-shaped like Earth. Thousands of such planets are expected to be found in the coming years. But it will be beneficial to settle on these planets only when their quality matches that of the Earth. That is, their size is equal to that of the Earth, it rotates like stars like the Sun and on this one day is equal to one day of ours. It is now to see how long it is going to take us to discover such a planet.
