Скачать или смотреть Are We Alone in the Universe? New Discoveries Say Maybe Not

For centuries, humanity has searched for signs of life beyond Earth.
Today, thanks to NASA’s James Webb Space Telescope, scientists are closer than ever to answering that question.
Researchers are studying the atmospheres of distant exoplanets, searching for biosignatures — chemical clues linked to life.
One planet in particular, K2-18b, has captured global attention.
Located 124 light-years away, K2-18b lies within its star’s habitable zone and may be covered by vast oceans.
Its atmosphere contains methane, carbon dioxide, and a mysterious molecule called dimethyl sulfide — a compound that, on Earth, is produced only by living organisms.
While this is not proof of alien life, it is one of the strongest hints ever discovered.
