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.
Brown dwarf — [contradicted] The claim that Teide 1 was discovered in 1995 by Rebolo, Zapatero-Osorio, and Martín :: The source explicitly states Teide 1 was discovered in images collected on 6 January 1994 by the IAC team (Rafael Rebolo, María Rosa Zapatero-Osorio, and Edu
Brown dwarf — [contradicted] The claim that Gliese 229B's near-infrared spectrum showed methane absorption, establishing the T spectral class, and that this object was discovered by Rebolo, Zapatero-Osorio, and Martín :: The source explicitly states Gliese 229B was discover
Constellation — [contradicted] the traditional 48 constellations listed by Ptolemy now number 38 after the division of Argo Navis into three constellations :: the source says 'The traditional 48 constellations, consisting of the zodiac and 36 more (now 38, following the divis
Asteroid — [contradicted] The total mass of all asteroids combined is only 3% that of Earth's Moon. :: The source says 'The total mass of all the asteroids combined is only 3% that of Earth's Moon.' (correct)
Comet — [contradicted] 'dirty snowballs' or 'icy dirtballs' :: The source explicitly says 'dirty snowballs' is the popular model, and that after the Deep Impact mission 'icy dirtballs' may be more appropriate, so both terms are supported, not contradicted.
Ceres (dwarf planet) — [contradicted] He initially thought it was a comet :: Piazzi thought it was a comet, but the source says he first thought it was a star and then a comet — the text says he was searching for a star, found 'a moving starlike object, which he first thought was a
Ceres (dwarf planet) — [contradicted] allowing Franz Xaver von Zach and Heinrich W. M. Ceres fit the Titius–Bode law almost perfectly :: The source states that von Zach and Olbers found Ceres, not 'Heinrich W. M. Ceres'; also the phrase 'Ceres fit the law' is garbled, but the source
Centaurus A — [contradicted] at 11 million light-years away (redshift 0.00183) :: flagged by an independent model family (deepseek-v4-flash) against the source article; the same-family audit missed it.
Centaurus A — [contradicted] Its overall magnitude is 7.0 :: flagged by an independent model family (deepseek-v4-flash) against the source article; the same-family audit missed it.
