This is a partial list of IC objects, which are astronomical objects included in the Index Catalogue of Nebulae and Clusters of Stars. This two volume catalog was published in 1895 and 1908 by J. E. L. Dreyer. The constellation information for this table is available from the NGC2000.0: Complete New General Catalog and Index Catalog. [1]

An astronomical catalogue is a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery. Astronomical catalogs are usually the result of an astronomical survey of some kind.
Articles with the IC number in the title use [[Category:IC objects|####]], dropping the IC prefix, and using only the number. The number should be padded up to 4 digits using zeroes. Articles without the IC number in the title use [[Category:IC objects]]. A redirect containing the IC number should also be added to the category, sorted as above.
The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use.
Unlike objects in the Messier catalogue, which are listed roughly in the order of discovery by Messier and his colleagues, [5] the Caldwell catalogue is ordered by declination, with C1 being the most northerly and C109 being the most southerly, [1] although two objects (NGC 4244 and the Hyades) are listed out of sequence.

The following is a list of NGC objects, that is objects listed in the New General Catalogue (NGC). It is one of the largest comprehensive astronomical catalogues for deep sky objects such as star clusters, nebulae, and galaxies.

All of the known life-forms show specific chiral properties in chemical structures as well as macroscopic anatomy, development and behavior. [26] In any specific organism or evolutionarily related set thereof, individual compounds, organs, or behavior are found in the same single enantiomorphic form.
