Two Rejected Planet Claims Return to NASA’s Archive—with False-Positive Labels, Not a Comeback Tour

The latest exoplanet archive false positives update has a distinction worth slowing down for. NASA’s Exoplanet Archive said October 15 that data for Gl 581 d and HD 149382 b had been added back with the designation False Positive Planet. This is not a confirmation that the previously refuted planet claims are correct. The records are returning; the claims are not receiving a clean bill of scientific health.

The archive explains that these objects had previously been removed following published refutations. Its newer approach preserves access to their data while identifying their false-positive status. The excluded-targets documentation distinguishes those accessible system records from the main confirmed-planet tables. Finding a name somewhere in an archive is therefore not enough to establish how the archive classifies it.

That is the fresh development here, separate from the young planet Elias 2-24 b already covered by DJF. The same weekly update also lists new planet entries and updated measurements, but this story concerns how rejected claims are documented. Neither restoration reports extraterrestrial life, artificial technology or a new signal from an alien civilization.

Analysis: retaining a clearly labeled unsuccessful claim can be scientifically useful. It preserves the history needed to understand what was proposed and how the evidence was reassessed. Deleting every trace would make a cleaner list, but not necessarily a more informative record. The important part is keeping the status visible instead of presenting all database entries as equivalent discoveries.

The distinction matters especially when old claims circulate without their later qualifications. A screenshot of a system page can look authoritative while omitting the classification that changes its meaning. Readers should check the object’s disposition, the relevant literature and the purpose of the table they are using. A search result is a starting point, not an astronomical certificate of existence.

It also shows why changing a scientific catalogue is not automatically evidence that researchers are concealing something. In this case, the update explicitly explains the restoration and the labels. That makes the record more inspectable. There is room to question a classification, but a useful challenge engages the observations and published arguments rather than treating the presence of an entry as a secret confession.

The verified news is an October 15 data-management update with consequences for interpreting exoplanet information. These two records are accessible as false positives, not restored as confirmed worlds. The search for other planets—and ultimately for life beyond Earth—depends on that discipline. Sometimes the most valuable new thing in the archive is a clearer explanation of what not to count.
