Atmospheric retrievals yielded strong evidence for water vapor (H2O) with a Bayes factor of log10BH2O=8.9 and strong evidence for carbon dioxide (CO2) with a Bayes factor of log10BCO2=52.3. ^[1] Researchers used the James Webb Space Telescope's NIRSpec G395H instrument to observe the hot Jupiter HAT-P-1 b over a wavelength range of 2.7 to 5.3 micrometers. ^[2] NASA offers a public pixel adoption program for its Nancy Grace Roman Space Telescope, allowing one pixel per email address. ^[3] The results establish HAT-P-1 b as a benchmark for comparative studies of hot-Jupiter atmospheric composition due to its oxygen-rich atmosphere and low carbon-to-oxygen ratio. ^[4] The study combined the new JWST data with archival observations from the Hubble Space Telescope's STIS and WFC3 instruments to create a comprehensive atmospheric analysis from 0.3 to 5.3 micrometers. ^[5] Participants receive a certificate with their pixel number, which they can print and share on social media. ^[6] The Nancy Grace Roman Space Telescope is a next-generation space observatory designed to study dark energy, exoplanets, and infrared astrophysics. ^[7] The Wide Field Instrument provides a field of view 100 times greater than the Hubble Space Telescope's infrared instrument. ^[8]
