Exoplanet Catalog Update
NASA adds eight planets—and removes one
The weekly Exoplanet Archive update expands the confirmed catalog while preserving a refuted candidate's history as a false positive.

Confirmed Catalog Update · No Life Detection
The NASA Exoplanet Archive's September 3 update added eight confirmed planets: CD-35 2722 B b; HD 50554 c and d; KMT-2025-BLG-0975L b; KMT-2025-BLG-1160L b; TOI-3053 b; TOI-3278 b; and TOI-4409 b. The list spans several detection and confirmation methods rather than announcing a single Earth analogue or habitable world.
The same update reclassified WASP-126 c as a false positive after a published refutation. Its system page remains available, while the object was removed from the confirmed planetary-system tables. That revision is scientific record-keeping working as intended: catalogs gain reliability by correcting themselves, and neither inclusion nor removal carries any claim about life or technology.
Why it matters
A living catalog that records both confirmations and reversals is the infrastructure behind credible claims about how common planets—and eventually potentially habitable worlds—really are.
What the source establishes
Confirmed NASA Exoplanet Archive update. Eight objects entered the confirmed tables and one was demoted; no biosignature, technosignature, or Earth twin was announced.
