Are we soon to more than double our exoplanet catalog? (Image credit: NASA/JPL-Caltech) Using NASA data and machine learning, scientists have found over 10,000 possible new planets in a single survey. In a new study, researchers used machine learning to perform a sweeping survey of data from NASA's exoplanet-hunting Transiting Exoplanet Survey Satellite ( TESS ). As a result, they and uncovered exactly 10,091 candidate planets that had never been seen before. To clarify, when planets beyond our solar system (otherwise known as exoplanets) are first spotted, they are considered "candidates" until they can be confirmed as such with the right amount of evidence. Some of these candidates might not end up being planets after all — some could end up being other objects or even just "noise" in the data. This major haul of exoplanet candidates, however, may beg the question: Why haven't these thousands of planets been seen before?…
