James Webb Space Telescope Discoveries: Cosmic Dawn & Exoplanet Atmospheres
Deployed to Lagrange Point L2, the James Webb Space Telescope operates 1.5 million kilometers from Earth, capturing infrared light from the dawn of time.


1. Why Infrared Astronomy Matters

As the universe expands, light emitted billions of years ago undergoes Cosmic Redshift, stretching visible light into infrared wavelengths. Infrared light also passes through interstellar dust clouds.


2. Major Discoveries

  • Galaxy JADES-GS-z14-0: Observed just 290 million years post-Big Bang.
  • WASP-96b Atmospheric Spectrum: Clear chemical signatures of water vapor and cloud haze on a distant exoplanet.
