James Webb May Have Just Found Life on K2-18 b | 124 Light-Years Away | 99.7% Confidence

Subscribe for more space mysteries: https://www.youtube.com/@MagneticSpaceX?sub_confirmation=1 One hundred twenty-four light-years from Earth, a planet orbits a dim red star in Leo, and something in its atmosphere is defying explanation. The James Webb Space Telescope has detected dimethyl sulfide at concentrations ten thousand times stronger than anything in our own skies, and on Earth, only living organisms produce this molecule. The confidence level stands at ninety-nine point seven percent, leaving only a three-in-one-thousand chance this is noise, and suddenly the question of whether we are alone feels less like philosophy and more like pending confirmation. In this groundbreaking space documentary, we explore K2-18 b - and what it means when the universe finally starts answering back. In this documentary, we go deep: → The 99.7% detection confidence and why scientists are calling this the strongest biosignature ever recorded from an exoplanet → Dimethyl sulfide concentrations 10,000 times greater than Earth's atmospheric levels - a molecule only life should make → K2-18 b's position in the constellation Leo, orbiting within its red dwarf's habitable zone at 124 light-years distance → The fierce debate between ocean world and lava planet - and why the Hycean hypothesis changes everything we thought possible → How JWST's infrared instruments pierced an alien atmosphere to detect the chemical fingerprints of potential biology We have spent centuries staring into the dark, asking if anyone is out there. The dark may finally be staring back. 0:00 - Introduction 2:33 - A Whisper from 124 Light-Years: The Genesis of a Discovery 19:40 - The Ghost in the Machine: Decoding K2-18 b's Atmosphere 43:42 - The Smoking Gun: Dimethyl Sulfide and the 99.7% Confidence 1:08:39 - K2-18 b: A Hycean World Unveiled 1:33:46 - Life's Blueprint: What DMS Implies for Alien Biology 1:58:01 - The Quest for Confirmation: Beyond DMS 2:25:44 - Are We Alone?
