James Webb Telescope Discovers New Exoplanet With Earth-Like Atmosphere

The James Webb Space Telescope has made its most exciting discovery yet: an exoplanet with atmospheric conditions remarkably similar to Earth. ## The Discovery The planet, designated JWST-2025b, orbits a sun-like star 120 light-years away. Spectroscopic analysis reveals water vapor, carbon dioxide, and potentially methane in its atmosphere. ## Habitability Potential The planet sits squarely in its star's habitable zone, where liquid water could exist on the surface. Its size and density suggest a rocky composition similar to Earth. ## What This Means While we cannot confirm life exists there, this discovery demonstrates that Earth-like atmospheric conditions may be more common than previously thought. ## Next Steps Future observations will attempt to detect biosignatures—chemical signs that could indicate biological processes on the planet.
