Dear MEL Topic Readers,

Breakthrough AI identifies 50 new planets from old NASA data

Astronomers are finding new exoplanets nearly every day. The closest star from our Sun is Proxima Centauri, located 4.2 light-years, or nearly 40 trillion kilometers away. Astronomers have already found to exoplanets orbiting this neighbor star, so they are the closest planets from us. To your surprise, they are just two of the 4,200 exoplanets that have been confirmed as of August. But how are astronomers identifying extrasolar planets that don’t shine themselves in the faraway universe?

Basically, they observe stars and look for dips in light, which are presumably caused by passing planets of the solar system. Sounds like a heavily attention-required work, doesn’t it? But now, machine-learning can train artificial intelligence to validate unidentified exoplanet candidates only in seconds. In fact, some researchers identified 50 new exoplanets with the help of AI algorithms from already-scrutinized NASA data. They are expecting that machine learning will further improve the algorithm and find more extrasolar planets, potentially habitable ones that our descendants of future generations might someday pay a visit.

Enjoy reading the article and learn about the quest for habitable planets of other stars.
