About Untitled Game

The Habitable Exoplanet Visualizer displays habitable zone exoplanets that have received human radio communication, with data sourced from the NASA Exoplanet Archive. It features scaled radii visualizations, sorting by right ascension or declination, and spectral type filters (M, K, G, F). A table lists historical human radio broadcasts with dates, frequencies, distances, and number of systems reached, updated as of August 2025. The page includes loading indicators and notes that errors are the author's own.
