New signals from deep space! Astronomers just announced the discovery of 8 potentially alien radio signals, using machine learning to comb through old data sets. These signals came from 5 different stars, all within 90 light years of Earth. One of them came from a G-type star, just like our own sun. Another one mysteriously stopped and reappeared 3 days later. And all were narrowband signals, which are rarely produced by natural sources. While follow-up observations have not yet confirmed these signals, intensive further study is now underway – and this new machine learning approach to combing signal data could radically accelerate the search for alien intelligence. It remains to be seen what these signals are. But this breakthrough suggests that the question of “are we alone?” may not be answered by us humans, but by our machines.
