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.

BL Lacertae object — The entry states that John L. Schmitt first noticed the peculiar nature of BL Lac in 1968 when he matched it with a radio object, VRO 42.22.01. In fact, Schmitt identified the optical counterpart, but the peculiar nature (rapid variability and polarization) wa
BL Lacertae object — The entry says 'Peter Albert Strittmatter proposed the class of object in 1972 and added four objects.' The term 'BL Lac object' was already in use by 1972, and the specific claim that he 'proposed the class' and 'added four objects' is not standardly attribut
Dark galaxy — The entry lists Dragonfly 44 as a best candidate dark galaxy, but Dragonfly 44 is an ultra-diffuse galaxy with visible stars, not a dark galaxy; listing it as such is factually misleading.
Dark galaxy — The entry lists 'AC G185.0-11.5' as a candidate, but the correct designation is 'AGC 1850-11.5' (or similar variant); the given format is not standard and is a typographical error.
Dark matter halo — Ken Freeman in 1970 did not propose undetected mass to explain flat rotation curves; his paper attributed the flatness to a specific mass distribution, and the first proposal of dark matter for this purpose is credited to others like Vera Rubin and Kent Ford,
Galactic halo — The NFW profile does not provide a finite gravitational potential for all distances; its potential diverges at large radii.
Galactic halo — NGC 4236 is not known in standard astronomical literature to have an active stellar halo.
Hubble sequence — The entry claims the Hubble sequence was originally devised by John Henry Reynolds and Sir James Jeans, but it was actually devised by Edwin Hubble.
Hubble sequence — The 'DID YOU KNOW' section repeats the false claim that the Hubble sequence was invented by Reynolds and Jeans, while the correct inventor is Edwin Hubble.
Interacting galaxy — The entry states that evidence for the galaxy harassment hypothesis has been undermined by similar structures in isolated galaxies, which misrepresents the current scientific consensus; galaxy harassment is a well-supported mechanism, and isolated dwarf ellipt
Low surface brightness galaxy — The claim that 'over 95% of their mass is in the form of non-baryonic dark matter' is an overgeneralization; not all LSB galaxies have over 95% dark matter.
Low surface brightness galaxy — The claim that 'the first LSB galaxy verified to exist was Malin 1, discovered in 1986' is inaccurate; earlier LSB galaxies were known before 1986, and Malin 1 is specifically the first giant low-surface-brightness galaxy.
Magellanic spiral — Magellanic spirals are not defined by having just one spiral arm; the Large Magellanic Cloud itself has a complex structure with multiple arms and a bar.
Magellanic spiral — The claim that main sequence stars occupy the single spiral arm while supergiants cluster in a thick rectangular bar is not a standard fact; stellar populations in these galaxies are more complex and not uniformly stratified in this way.
