Скачать или смотреть K2-18b Explained: NASA’s Most Promising Alien World

Discovered over 120 light-years away in the constellation Leo, K2-18b is an exoplanet that has scientists buzzing. This video takes a deep dive into the mysterious Hycean world that may hold the most promising signs of extraterrestrial life we've ever seen.

Using new data from the James Webb Space Telescope, scientists have detected water vapor, methane, carbon dioxide, and possibly even dimethyl sulfide — a potential biosignature. K2-18b orbits within the habitable zone of a red dwarf star, raising the question: could life really exist there?

In this video, we’ll explore:

-What makes K2-18b so different from Earth — and why that’s a good thing
-How far K2-18b is from Earth and whether we’ll ever visit it
-What kind of alien life could survive on a planet with a hydrogen-rich atmosphere
-How K2-18b compares to Earth in size, composition, gravity, and temperature
-Why scientists believe K2-18b might be our best chance at detecting life beyond our solar system

Join us as we explore the search for alien life, the future of space exploration, and what the discovery of a sub-Neptune habitable planet means for humanity.
