Artificial intelligence software is being used to look for signs of alien lifeforms.
There are between 10 and 50 billion potentially habitable worlds in our galaxy, says Bill Diamond. It makes his job rather difficult.
But new tools are helping the search. The ability of artificial intelligence to both handle massive datasets - and to spot anomalies - is transforming the hunt for alien intelligence. He points to AI making it possible to search for new types of radio signals from alien sources. He explains that traditionally, Seti has looked for narrowband signals similar to those used by human beings.
His team did this by simulating both types of noise, and then training their AI to differentiate between the two. However, organic compounds can be created by non-biological processes, meaning that it's not yet possible to say whether they derive from past life on the planet.
