Loading contentTESS, the Transiting Exoplanet Survey Satellite, scans large swaths of the sky in turn, monitoring bright, nearby stars for the telltale dips of transiting planets.
By focusing on relatively bright, nearby stars, TESS finds planets that are easier for other observatories — including the James Webb Space Telescope — to study in detail afterward.
Where Kepler stared deeply at one region to measure how common planets are, TESS surveys the whole sky to find the nearest and best examples for further investigation.
How this connects across Asteria Star — scientific, cultural, and astrological links are kept separate.
