ABSTRACT

The Solar System is the gravitationally bound system of the Sun and it contains eight planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. From all these planets only Earth has found life still this date. It is said that there are more planets in the Universe than the stars, still now we are not able to find a planet like Earth which produce variety of life forms. As the technologies are advancing especially in the field of Telescopes Scientists are able to discover more than 4,000 exoplanets and thousands of exoplanets are waiting to be confirmed by further observation. There were 24 planets discovered under habitable zone and may support life just like Earth. Humans are born to explore and in future till 2050 Mars will be our next home. It may also possible that one day these exoplanets will be our new home after Mars. Scientists are using new technologies and methods to find the exoplanets and life on it. It is not easy to find molecules and atoms in the atmosphere of planets which are very far away. The nearest star Proxima Centauri is 4.2 light years away from the Earth. But now with the help of powerful Telescope like James Web Telescope can make this possible which is going to launch in year 2021. This Telescope will help the Scientists to find molecules which are only produce by living organisms, this will prove the life sustainability of an exoplanets and will answer the Humanity’s oldest question, are we alone?
