Machine-learning algorithm trained on synthetic planetary systems has identified 44 stars that have a high probability of hosting a rocky planet in their habitable zone.

The algorithm identified 44 systems that are highly likely to harbor undetected Earth -like planets.

Astronomers can now follow up on these targets rather than searching stars blindly.

Alibert says algorithm should be able to narrow down thousands of systems to the few that have a higher chance of supporting an Earth -like planet.

"This is a significant step in the search for planets with conditions favorable to life," he says.

The findings are published in the April 2025 issue of the journal Astronomy & Astrophysics .
