NASA confirmed the existence of 301 exoplanets using its neural network called "ExoMiner." The discovery brings the total number of validated exoplanets — or those that orbit a star outside our solar system — to 4,569.
- ExoMiner relies on NASA's Pleiades supercomputer and Kepler space telescope data to function.
- Scientists initially detected the 301 planets by combing through Kepler datasets. ExoMiner supplemented their work by validating which ones were real and which were false positives.
- Project lead Hamed Valizadegan called ExoMiner "highly accurate," noting that it's more reliable in some ways than human experts and current machine classifiers due to biases in human labeling.
- None of the newly confirmed planets were in the habitable zones of the stars they orbit, researchers said.
