Ever since man started looking at this huge universe and turning his eyes to the stars, man has been troubled by the question, are we alone in this vast universe, are there other people also? Are there lives like ours, is there anyone else present in our solar system?

The Fermi paradox, which is named after the Italian-American physicist Enrico Fermi, states that there is a clear contradiction between the lack of evidence for extraterrestrial civilizations and the various high estimates for their probability, and whether in the universe extraterrestrial civilizations like us may or may not exist, but both possibilities seem terrifying.

First exoplanet confirmed

When the first exoplanet was confirmed in 1992, it was doubtful that there were any planets outside in our solar system. Today, we know more than thousands of stars around the planet and planets inside the various constellations on which the environment is similar to our Earth, but we still do not know if there is a position anywhere in these planets that gives life Affects? Do they support the arrangement of the planets in the Earth’s orbit in making the planets of the home planets? Space organizations around the world are still researching these planets and exploring the possibilities of life on them.

How are the Environment of other planets to support life?

We must initially explore them before we can decide whether other planets have contours to support life. NASA Science followed this objective by supporting an attractive suite of ground-based assumptions through the Kepler mission, a space-based observatory that focuses on the generality (what is the number per star there) of extrasolar planets, and from the medium of action, TESS (Transiting Exoplanet Survey Satellite), which is conducting an all-sky study to find exoplanets traveling in gas goliaths from the size of Earth.

Let us now know the evidence which states that we are not alone in this universe.

The SETI (search for extraterrestrial intelligence) has been conducting research on Aliens for decades, but for the first SETI meeting in 1960, Dr. Frank Drake devised an equation to estimate the number of communicative aliens civilization in space. Drake argues that sheer possibility means there must be aliens. Radio signals have been seen by SETI scientists, mainly from alien civilizations.

In 1977 OHIO scientists discovered the ‘WoW’ signal, did much research on the ‘WoW’ signal for many years but could not detect it again. The researchers CHARLES FORT and ERICH VAN DANIKEN believe that We have been contacted already by aliens in ancient times. There is little evidence to support his theories, but thousands of people worldwide claim to have seen the UFO (Unidentified flying object).

In 1947, Roswell Army Air Field announced that a UFO had crashed in New Mexico, and soon began to spread the news of spacecraft testing and aliens autopsy in Area 51, but no reports have been officially confirmed. About 10% of all UFO sightings are unexplained, leading physicists like STEPHEN HAWKING believe that Alien life exists, but they also say that we are not ready to meet a more advanced civilization.

Our galaxy has several hundred billion stars.

Many of which have the possibility of orbiting planets. As if that mind-to-mind is not enough, astronomers believe that there are at least one trillion galaxies in the visible universe. Given the possibility of planets, it does not appear that we are alone in the universe. And so scientists around the world have called him the discovery of SETI, or supernatural intelligence. So far, SETI scientists have found nothing even after years of scanning the sky for radio signals that could indicate such a life is.

Scientists around the world will continue to do Research on Aliens. But what will happen when we meet Aliens civilization?
