JWST Captures Exoplanet Tylos Shedding Gas, Forming Twin Comet Tails

  • James Webb Space Telescope (JWST) observed exoplanet 'Tylos' (WASP-69b) with two comet-like tails.
  • Tylos, a hot gas giant, is experiencing extreme atmospheric loss due to its close orbit to its star.
  • The planet's escaping gas and dust form two vast tails stretching millions of kilometers.
  • JWST's infrared spectroscopy enabled the detailed detection and resolution of these planetary tails.
  • This discovery provides crucial insights into planetary evolution, atmospheric escape, and habitability limits.

Why It Matters: It reveals planetary evolution, atmospheric loss, and habitability limits.
