new general catalogue
Low frequency (specialized term)Technical / Scientific
Definition
Meaning
A standard astronomical catalogue of deep-sky objects, originally compiled in the 19th century, that designates celestial objects with an 'NGC' number (e.g., NGC 224).
Often used to refer to the entire system of NGC object identification, or the objects catalogued within it. In casual astronomy contexts, it can refer to any such standard reference list.
Linguistics
Semantic Notes
The term refers to a specific, named catalogue. It is usually capitalized in full (New General Catalogue) when referring to the original work, but often appears in lowercase in running text. The acronym 'NGC' is more common than the full term.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'New' as 'новый' in a contemporary sense; it's part of a historical name ('New' as opposed to older catalogues).
- The word 'General' does not mean 'военный генерал'; it means 'all-encompassing' or 'comprehensive'.
- Do not confuse 'catalogue' (каталог) with a simple list; it implies a systematic, reference publication.
Common Mistakes
- Incorrectly capitalising all words in running text (e.g., 'the New General Catalogue').
- Using 'New General Catalog' (American spelling) to refer to the specific historical work (the original title used 'Catalogue').
- Confusing it with the 'Index Catalogue' (IC), which is a supplement.
