AI Tool RAVEN Confirms Over 100 Exoplanets from NASA TESS Data — Including 31 New Worlds
Summary
Astronomers at the University of Warwick have deployed a powerful new AI tool called RAVEN to analyze data from NASA’s Transiting Exoplanet Survey Satellite (TESS) mission, confirming over 100 exoplanets and discovering 31 previously unknown worlds. The tool also identified thousands of additional exoplanet candidates for follow-up investigation.
RAVEN represents a significant leap in how astronomical data is processed. TESS generates massive volumes of light curve data — brightness measurements of stars over time — that must be analyzed for the telltale dips indicating a planet passing in front of its host star. Traditional analysis methods are time-consuming and prone to false positives. RAVEN uses machine learning to rapidly sift through this data with higher accuracy and speed than previous approaches.
The 31 newly confirmed exoplanets add to humanity’s growing catalog of known worlds beyond our solar system. The discovery also demonstrates how AI is accelerating scientific discovery by handling data analysis tasks that would take human researchers orders of magnitude longer to complete.

Commentary
This is AI doing what it does best — pattern recognition at scale on data volumes that would drown human analysts. TESS has been watching millions of stars, and the bottleneck has always been analysis, not observation. RAVEN effectively removes that bottleneck.
What’s particularly exciting is the thousands of additional candidates identified. Each of those represents a potential world that could be followed up with more detailed observations from instruments like JWST. We’re entering an era where AI doesn’t just assist astronomical discovery — it drives it. The 31 new worlds confirmed here are likely just the beginning of what RAVEN will find as it continues processing the TESS archive.
