Скачать или смотреть The Cosmic Origin of Your DNA: The Definitive Proof in an Asteroid

Are you really from Earth? The answer might surprise you. Your genetic code, the DNA that defines you, might have a cosmic passport.
This short documentary explores the incredible evidence that the basic building blocks of life arrived on our planet from space. For years, scientists couldn't find all the "letters" of DNA in meteorites, which left a huge question mark.
Join us to discover how a new analysis and NASA's bold OSIRIS-REx mission to the asteroid Bennu solved the mystery. In a perfectly uncontaminated, 4.5-billion-year-old dust sample, scientists found the almost complete recipe for life: all five nucleobases of DNA and RNA, and the phosphates that bind the structure together.
This discovery suggests that the ingredients for life are not exclusive to our planet but are distributed throughout the universe, waiting for the right conditions to awaken.
