James Webb Found Oxygen on a Planet Only 26 Light Years Away !

Twenty-six light-years away, a distant world may have just changed everything. In this video, we explore one of the most extraordinary discoveries in modern astronomy: the James Webb Space Telescope detecting oxygen in the atmosphere of exoplanet K2-18 b. Oxygen is not just another gas—it is the same element that sustains life on Earth, and its presence on a distant planet raises a question humanity has asked for thousands of years: are we alone? You’ll learn how Webb analyzed faint starlight passing through an alien atmosphere, how transmission spectroscopy reveals chemical fingerprints across interstellar distances, and why oxygen, water vapor, and other molecules make K2-18 b one of the most compelling worlds ever studied. We’ll also break down what makes this planet unique—a super-Earth orbiting a red dwarf star in the habitable zone—and why such worlds may be far more common than planets like Earth. From the technology behind Webb’s golden mirror to the broader implications for astrobiology, this video explores how a single discovery could reshape our understanding of life in the universe. This is not a claim of alien life—but it is the strongest evidence yet that the conditions for life may exist far beyond our solar system.
