Biosignature Disequilibrium Detector — Exoplanet Transit Spectroscopy

Interactive 3D exoplanet transit simulator: tune a photosynthetic biosphere, volcanic outgassing and stellar UV flux, watch the planet transit its star, and read the resulting O2/CH4 transmission spectrum to spot a real chemical-disequilibrium biosignature versus an abiotic false positive.

Watch a rocky exoplanet transit its host star while an atmospheric photochemistry model runs underneath. Photosynthesis and volcanic outgassing feed oxygen and methane into the atmosphere; stellar UV drains them away. The retrieved transmission spectrum panel shows the resulting absorption bands for O₂/O₃, CH₄, H₂O and CO₂, and a live disequilibrium score tells you whether the combination you built would read as a genuine chemical-disequilibrium biosignature, an ambiguous case, or an abiotic false positive — the same reasoning astrobiologists apply to real JWST transmission spectra.

⚙ Under the hood

Watch an exoplanet transit its star while a photochemistry model tracks O2 and CH4 build-up from a biosphere, volcanism and stellar UV, then read the live transmission spectrum to tell a real chemical-disequilibrium biosignature from an abiotic false positive.
