Is Earth unique or is life a common phenomenon throughout the universe?

This documentary explores one of humanity’s biggest questions using the most groundbreaking discoveries of modern astronomy. From subsurface oceans on Europa and Enceladus, to methane seas on Titan, to flowing water on Mars, scientists now believe our own solar system may host multiple places where life could exist. If life emerged twice in one star system, it may be everywhere.

But the search doesn’t end here.

Thanks to NASA’s Kepler Space Telescope, astronomers have confirmed more than 1,000 exoplanets with billions more expected across the Milky Way. Worlds like:

🌍 Kepler-186f — the first Earth-sized planet in a habitable zone
🌍 Kepler-62e & 62f — possibly covered in vast global oceans
🌍 Kepler-452b — “Earth’s older cousin,” orbiting a star just like our Sun
🌍 Trappist-1 system — seven Earth-sized planets orbiting a tiny red dwarf

These discoveries revolutionize our understanding of what it means for a planet to be “habitable.”

The film also explores:

• How astronomers detect planets using transit and radial velocity methods
• The concept of the Goldilocks Zone
• Why life might thrive even outside habitable zones
• SETI’s search for intelligent signals among the stars
• The future of exploration with JWST, ESA’s CHEOPS, and other next-gen telescopes

With billions of Earth-like planets and countless moons with oceans, scientists now believe discovering extraterrestrial life is not a matter of if — but when.
