The search for other Earth-like planets - Olivier Guyon · 6:21 · Video: TED-Ed · Watch at the source

In short: With billions of stars in our galaxy and billions of galaxies in the universe, the scale of space is staggering. This video explores the challenge of searching for Earth-like planets within these astronomical numbers.

Olivier Guyon examines the immense scale of the cosmos, noting it would take a thousand years just to count the stars in our own galaxy. Beyond that, it would take another thousand years to count the galaxies in the universe. Within these vast numbers, scientists are searching for planets that might be ripe with life.
