Warm Gas-Giant Exoplanet WASP-107 b Transmission Spectrum (Hubble WFC3, Webb NIRCam, and Webb MIRI

Caption

This transmission spectrum, captured using NASA’s Hubble and James Webb space telescopes, shows the amounts of different wavelengths (colors) of starlight blocked by the atmosphere of the gas-giant exoplanet WASP-107 b. The spectrum includes light collected over four separate observations using a total of three different instruments: Hubble’s WFC3 (Wide Field Camera 3) Grism Spectrometer in green, Webb’s NIRCam (Near-Infrared Camera) Grism Spectrometer in orange, and Webb’s MIRI (Mid-Infrared Instrument) Low-Resolution Spectrometer in pink. This spectrum shows clear evidence for water (H2O), carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), sulfur dioxide (SO2), and ammonia (NH4) in the planet’s atmosphere, allowing researchers to estimate the interior temperature and mass of the core.
