5 EARTH-LIKE PLANETS FOUND! Is there life there?

Could a second Earth really exist somewhere beyond our solar system? Astronomers have discovered thousands of exoplanets, but only a few have characteristics that make them particularly interesting candidates in the search for life. In this article, we examine the five planets most similar to Earth and investigate whether any of these distant worlds might harbor water, an atmosphere, oceans, or even signs of life.

Among the most interesting candidates are Kepler-452b, Teegarden b, TOI-700 d, LHS 1140 b, and K2-18 b. Each of these planets is different, each located in a completely different solar system, but all have become important targets in modern astronomy.

Why are scientists so intensely searching for Earth-like planets? Key factors include their size, mass, distance from their star, and location in the so-called habitable zone. It's there that, under the right conditions, the temperature could allow liquid water—one of the most important ingredients of life as we know it—to exist.

But the real excitement begins at K2-18 b. Observations by the Hubble and James Webb telescopes have allowed us to study the atmosphere of this distant planet. Signs of water appeared in the data, and later observations also pointed to the possibility of methane and carbon dioxide. Reports of the possible presence of dimethylsulfide, a compound that on Earth is largely associated with marine life, have generated even greater interest.

Does this mean that life beyond Earth has been found?

No. This is crucial: the presence of dimethylsulfide on K2-18 b has not yet been conclusively confirmed, and the interpretation of the data remains a subject of scientific debate. Further, much more precise observations are needed.

But if astronomers one day find a reliable chemical signature of life in the exoplanet's atmosphere, it will be one of the greatest discoveries in human history.

The film also delves much further into the future. We ponder the Fermi Paradox: if there are billions of galaxies and an unimaginable number of planets in the Universe, why haven't we found any clear signs of alien civilizations yet?

Is life incredibly rare? Do intelligent civilizations die out before they can contact us? Or are there worlds far away, waiting to be discovered for millions of years?
