AI-Assisted TESS Search Uncovers 11,554 Exoplanet Candidates, Including 10,091 New Finds

Joshua T. Roth’s team used a machine learning-assisted pipeline to identify 11,554 exoplanet candidates in NASA TESS data, including 10,091 not previously detected and 411 single-transit events.
The search scanned uniformly cleaned light curves for 83,717,159 stars from TESS’s first observing cycle, targeting fainter stars that earlier surveys often skipped because their signals are noisier and harder to validate.
Those signals remain candidates rather than confirmed planets, since some will prove to be eclipsing binaries, instrumental artifacts or other false positives after follow-up checks.
One follow-up test already confirmed TIC 183374187 b—a hot Jupiter found with Magellan/PFS radial-velocity measurements—showing the pipeline can recover genuine planets from underused archival data.
The haul more than doubles the known pool of TESS exoplanet candidates and highlights a broader AI role in science: screening huge archives so experts can focus scarce telescope time on the most promising targets.
With 10,000 new candidates, how will we prioritize the search for the next Earth-like world?
What cosmic secrets are hiding in astronomical data we have previously ignored?
As AI finds planets faster than we can confirm them, is our technology creating an impossible scientific backlog?
TESS Unveils 10,000+ New Exoplanet Candidates: How AI and Big Data Are Transforming the Search for Alien Worlds
Overview
In April 2026, a Princeton-led team announced the discovery of over 10,000 new exoplanet candidates, marking a record-breaking leap in exoplanetary science. These candidates were identified from the first year of data collected by NASA's TESS, which surveyed about half of the night sky. This unprecedented surge highlights TESS's power and the shift toward large-scale, demographic studies of planetary systems. The discovery not only expands our understanding of planets beyond our solar system but also sets the stage for future research, as scientists now focus on confirming and characterizing these potential new worlds.
