Laut einem Artikel im Astrophysical Journal haben wir 10.000 neue Kandidaten die bestätigt werden müssen :
For most of human history, we did not know if any other planets existed beyond our own solar system. The first confirmed exoplanet around a Sun-like star was discovered in 1995. In a single study published this year, astronomers added over 10,000 potential new worlds to the list.
A team led by Princeton University analyzed the light curves of over 80 million stars observed by NASA's TESS satellite during its first year of operation, using a machine learning pipeline to sift through data at a scale no human team could manually review. Out of 11,554 candidate signals they identified, 10,091 had never been detected before.
That single survey produced more candidates than the entirety of NASA's Kepler mission, which itself ran for nine years and fundamentally transformed our understanding of how common planets are in the galaxy.
The key word is candidates. When planets are first spotted they are considered candidates until confirmed with sufficient evidence. Some of these signals may turn out to be other objects or noise in the data. Confirmation requires follow-up observations, which takes time. But even a fraction of these holding up would represent a massive expansion of known worlds.
The reason these candidates were missed before is that TESS typically focuses on brighter stars. This survey targeted stars up to 16 times fainter, dramatically expanding the searchable sky.
All the new candidates orbit their stars with periods between 12 hours and 27 days, meaning they sit very close to their stars and are likely far too hot to be habitable. But each one tells us more about how planetary systems form and what kinds of worlds the galaxy actually contains.
We have confirmed roughly 6,200 exoplanets across all of recorded astronomy. One survey of old data, reanalyzed with modern AI, nearly doubled that number overnight. The universe has not changed. We just got better at reading it.
