We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Planetary nebula — The entry states that William Herschel distinguished planetary nebulae from galaxies, but the concept of galaxies as separate systems did not exist in his time; this is an anachronism.
Planetary system — The entry uses a future date '23 April 2026' as if it were a confirmed historical fact, which is speculative and not a factual statement about real canon/history.
Pleiades — NGC 1432 is a reflection nebula, not an HII region.
