The telescope that revealed thousands of exoplanets.
The Kepler Space Telescope stared at a single region of sky, monitoring the brightness of many thousands of stars. When a planet crosses in front of its star, it blocks a tiny fraction of the light — a transit — which Kepler could detect.
Kepler discovered thousands of exoplanets and candidates of many sizes and orbits, demonstrating that planetary systems are common throughout the galaxy.
After running low on the fuel needed to point precisely, Kepler was retired in 2018. Its results reshaped our understanding of how many planets exist and set the stage for follow-up surveys.
How this connects across Asteria Star — scientific, cultural, and astrological links are kept separate.
