October 8, Tuesday, cosmologist, who was awarded the Nobel prize in physics, said he is convinced that extraterrestrial life exists and that we are likely to find evidence of this in over 30 years. Speaking at a London event earlier this week, the 52-year-old Swiss researcher Didier Celos suggestedthat the chances of finding life outside of our planet are large enough. Kilos, who is currently working at Cambridge University in the UK, received the Nobel prize for the discovery of the first planet outside the Solar system nearly a quarter of a century ago.
Nobel prize in physics in 2019
In 2019 the Nobel prize in physics was awarded for groundbreaking discoveries in astronomy. Didier Celos shared the prize with Dr. of philosophy at Princeton University, Michelle Major, who in 1995 found similar to Jupiter exoplanet 51 Pegasi b, orbiting the star at a distance of about 50 light years from Earth. Together, scientists have determined the planet, using a proven and tested technique known as Doppler spectroscopy, which looks for tiny variations that the star does, when the planet revolves around it. Also the award was presented to James Pills for theoretical discoveries in the field of physical cosmology.

Life beyond Earth
But back to the opening Celosa and Major. Since the discovery of 51 Pegasi b was discovered more than 4000 confirmed exoplanets that have revolutionized our understanding of the Universe and instilled hope for the search for life beyond the Solar system. Discovery scientists have demonstrated that in space there are other worlds. This discovery has expanded our horizons. According to Kilosa, we are hardly the only life in the Universe. The scientist believes that in the vastness of space, too many planets, too many stars, and the chemistry of life is universal. and chemistry is universal. Chemistry, which led to the emergence of life on Earth is to beget life in other places, so for the next 30 years we will create more advanced technologies that can better detect signs of biological activity in the distant worlds.
According to Lisa Kaltenegger, Director of the Institute Carl Sagan at Cornell University and one of the leading experts on ekzoplaneta in the world, the discovery of these distant worlds has paved the way for new methods of detecting the existence of alien life. And it’s hard to argue. In the end, the scientists found that every fifth star has a planet very similar to ours. Given that only in our galaxy 200 billion stars, the odds of finding alien life is very high.
What astronomers will look for in the future?
The next step for astronomers is to collect sufficient light from these small planets in the habitable zone. It is necessary to find out whether there are signs of life in the atmosphere of other worlds. The researchers note that modern telescopes can collect enough data to understand are we alone in the Universe or not. So, the telescope James Webb is the next — generation telescope. Launch of his work is scheduled for 2021. I guess that’s when the intricate details and properties of exoplanets will be discovered.
By the way, recently scientists who spetsializiruyutsya on the search for extraterrestrial life, welcomed the news that water vapor was first detected in the atmosphere of extrasolar planets — “super-earths” K2-18b, are located at a distance of 110 light years from Earth. And when do you think we will find aliens and we find? Share your thoughts in the comments and with members of our Telegram chat.
