    "prose": "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]\n\nResearchers 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]\n\nNASA offers a public pixel adoption program for its Nancy Grace Roman Space Telescope, allowing one pixel per email address. [^3]\n\nThe 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]\n\nThe 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]\n\nParticipants receive a certificate with their pixel number, which they can print and share on social media. [^6]\n\nThe Nancy Grace Roman Space Telescope is a next-generation space observatory designed to study dark energy, exoplanets, and infrared astrophysics. [^7]\n\nThe Wide Field Instrument provides a field of view 100 times greater than the Hubble Space Telescope's infrared instrument. [^8]",
