To take on the challenges, astronomers are turning to machine learning and artificial intelligence (AI) to build new tools to rapidly search for the next big breakthroughs. Planet hunting: There are a few ways to find a planet but the most successful has been by studying transits. Gravitational waves: Time-series models aren’t just great for finding exoplanets, they are also perfect for finding the signals of the most catastrophic events in the universe. Gravitational lenses: One celestial phenomenon that excites many astronomers is strong gravitational lenses. In 2018, astronomers from around the world took part in the Strong Gravitational Lens Finding Challenge where they competed to see who could make the best algorithm for finding these lenses automatically.
