AI tool RAVEN confirms over 100 exoplanets in NASA TESS data

Astronomers at the University of Warwick have used a new AI system called RAVEN to confirm more than 100 exoplanets from NASA's Transiting Exoplanet Survey Satellite (TESS) data. The discoveries include 31 newly identified worlds, many orbiting close to their stars, along with thousands of candidates. The findings reveal rare planet types and precise measurements of planetary occurrence rates around Sun-like stars.

Astronomers identify 10,000 new exoplanet candidates in TESS data

April 27, 2026 በAI የተዘገበ

Astronomers have discovered more than 10,000 previously unidentified candidate exoplanets by re-analyzing data from NASA's Transiting Exoplanet Survey Satellite. The findings, led by Joshua Roth at Princeton University, reveal planets orbiting fainter stars up to 6800 light-years away. While many candidates may prove real, experts caution about a high false positive rate.
