Explore Exoplanet Atmospheres

Investigate the atmospheres of planets outside our solar system, then make a pitch for what exoplanet spectra you’d like to capture with the James Webb Space Telescope.

WASP-17b Case Study Part 2: Hot, Hazy, Humid, Salty!

Spectrum Tool.

  1. Under plot type, select "line chart."
  2. Under the Source 2 dropdown menu, select category Atoms and Molecules and choose different comparison spectra to identify what might be present in the atmosphere of WASP-17b. Use this information to answer questions about the Atmospheric Chemistry columns in your Notebook table.
  3. Under the Source 2 top dropdown menu, select category Exoplanet Models and choose different model spectra for Hot Jupiter planets to identify what conditions might be present in the atmosphere of WASP-17b. Use this information to answer questions about the "Weather" columns in your Notebook table.

Spectrum Notebook. Answer this question in your Notebook.

  1. The Table in your Notebook shows a potential analysis of the WASP-17b spectrum. Based on your exploration of the Atmospheric Chemistry and Weather, explain why you would agree or disagree with this analysis.
