On October 8, the cosmologist who wasawarded the Nobel Prize in Physics, said that he is convinced that extraterrestrial life exists and that we are likely to find evidence of this within 30 years. Speaking at a London event earlier this week, 52-year-old Swiss researcher Didier Keloz suggested that the chances of finding life outside of our planet are quite large. Kelos, who currently works at Cambridge University in the UK, received the Nobel Prize for discovering the first planet outside the solar system almost a quarter century ago.
2019 Nobel Prize in Physics
In 2019, the Nobel Prize in Physics was awardedfor revolutionary discoveries in astronomy. Didier Kelos shared the award with Princeton Ph.D. Michelle Major, who in 1995 discovered Jupiter-like exoplanet 51 Pegasi b orbiting a star about 50 light-years from Earth. Together, scientists identified the planet using a tried and tested method known as Doppler spectroscopy, which looks for the tiny vibrations a star makes when a planet rotates around it. The prize was also awarded to James Peebles for theoretical discoveries in the field of physical cosmology.

Life Beyond the Earth
But back to the discovery of Kelos and Major. Since the discovery of 51 Pegasi b, more than 4,000 confirmed exoplanets have been discovered, which revolutionized our understanding of the universe and inspired hope for a search for life outside the solar system. The discovery of scientists has demonstrated that there are other worlds in space. This discovery has expanded our horizons. According to Kelos, we are hardly the only life in the universe. The scientist believes that there are too many planets in the open spaces, too many stars, and the chemistry of life is universal. and chemistry is universal. The chemistry that led to the emergence of life on Earth should give rise to life in other places, so over the next 30 years we will create more advanced technologies that can better detect signs of biological activity in distant worlds.
According to Lisa Kaltenegger, Director of the InstituteCarl Sagan of Cornell University and one of the leading experts on exoplanets in the world, the discovery of these distant worlds paved the way for new methods of detecting the existence of alien life. And it's hard to argue with that. In the end, scientists found that every fifth star has a planet that is very similar to ours. Given that there are 200 billion stars in our galaxy alone, the probability of finding an alien life is very high.
What will astronomers look for in the future?
The next step astronomers will be collectingenough light from these small planets in the habitable zone. This is necessary to find out if there are signs of life in the atmosphere of other worlds. Researchers note that modern telescopes today can collect enough data to understand whether we are alone in the universe or not. So, the James Webb telescope is the next generation telescope. The launch of its work is scheduled for 2021. I believe that it is then that the complex details and properties of exoplanets will be revealed.
By the way, more recently, scientists whospecializing in the search for extraterrestrial life, welcomed the news that water vapor was first detected in the atmosphere of an exoplanet - “super-earth” K2-18b, located 110 light-years from Earth. And what do you think, when we find aliens and find? Share your thoughts in the comments and with the participants of our Telegram chat.
