EXPLORE THE COSMOS
Search, filter, and sort the complete catalogue of confirmed exoplanets. Find planets by discovery method, star type, orbital characteristics, or habitability potential. Every entry includes detailed scientific data from peer-reviewed sources.
ATMOSPHERIC SPECTRA
Browse JWST and Hubble transmission spectra for planets where atmospheric data is available. Toggle molecular overlays for CO2, CH4, H2O, CO and more to see which absorption features have been detected.
3D SYSTEM VIEW
Step into a planetary system in 3D — see each planet's orbit around its host star with realistic shading and a visualisation of the habitable zone. On iPhone and iPad you can also place a system into your environment in AR.
COMPARE WORLDS
Analyze exoplanets side-by-side — or compare them with Solar System planets like Earth, Jupiter, and Mars. Compare sizes, masses, orbital periods, star properties, and habitability scores to understand what makes each world unique.
HABITABLE ZONE VISUALIZATION
See exactly where planets orbit within their star's habitable zone — the region where liquid water could exist. Identify potentially Earth-like worlds and understand the conditions for life beyond our solar system.
