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.

Active galactic nucleus — The entry states that Soviet-Armenian astrophysicist Viktor Ambartsumian introduced the concept of active galactic nuclei in the early 1950s, but his explosion hypothesis is not the same as the modern accretion-powered AGN model, making the claim misleading.
Active galactic nucleus — The entry contains an incomplete sentence about the redshift of quasar 3C 273, cutting off before stating the implied conclusion that the object is at a cosmological distance.
Andromeda Galaxy — The supernova S Andromedae is described as 'the first supernova ever recorded in that galaxy', but the entry later says 'though others like SN 1985F have since been detected' — SN 1985F is not a supernova in the Andromeda Galaxy; it occurred in NGC 4618.
Andromeda Galaxy — The statement that the Andromeda Galaxy is the largest member of the Local Group in terms of extension is ambiguous and not universally accepted; the Milky Way may have a larger physical diameter in some measurements.
