Scientists may have detected more than 10,000 never-before-seen exoplanets in a single survey, potentially tripling the number of known alien worlds in one fell swoop. The record-breaking haul was possible thanks to a new algorithm that helped researchers analyze more than 80 million stars — revealing subtle clues that would otherwise be "impossible" for us to see.Since the first alien planet was spotted in 1995, the number of exoplanet discoveries has slowly risen in line with new technologies, such as the James Webb Space Telescope, which are better equipped to spot these weird alien worlds. In September 2025, astronomers revealed that the number of confirmed exoplanets had surpassed 6,000, and nearly 300 have been added to the list since then, according to NASA.Using a machine learning algorithm, the team analyzed the light curves of precisely 83,717,159 stars captured by NASA's Transiting Exoplanet Survey Satellite (TESS), a car-sized space telescope that has been circling Earth since 2018. By looking for subtle dips in the stars' brightness, astronomers can tell when a planet has likely passed in front of, or transited, its home star.This revealed more than 11,000 exoplanet candidates, of which 10,052 had never been seen before.
