The NGC/IC Catalogue


NGC 869 / NGC 884

NGC 869 (h) and NGC 884 (χ) are two open clusters located 7,600 light years away in the constellation of Perseus. The clusters are most likely around 13 million years old. NGC 869 is the westernmost of the Double Cluster. NGC 869 and 884 are often designated h and χ Persei, respectively. Some confusion surrounds what Bayer intended by these designations. It is sometimes claimed that Bayer could not have resolved the pair into two patches of nebulosity, and that χ refers to the Double Cluster and h to a nearby star. The clusters are both located in the Perseus OB1 association, a few hundred light years apart from each other.

NGC 2903 / NGC 2905

NGC 2903 is a barred spiral galaxy about 30 million light years away in the constellation Leo. It was discovered by William Herschel who cataloged it on November 16, 1784. NGC 2905 is a bright star cloud within this galaxy. NGC 2903 has a very high speed of creating new stars in the central region and is part of the Virgo Supercluster.

NGC 4565

NGC 4565 (also known as the Needle Galaxy) is an edge-on spiral galaxy about 30 to 50 million light years away in the constellation Coma Berenices. It lies close to the North Galactic Pole and was first recorded in 1785 by William Herschel. NGC 4565 is a giant spiral galaxy more luminous than the Andromeda Galaxy and has at least two satellite galaxies, one of which is interacting with it. NGC 4565 is one of the brightest member galaxies of the Coma I Group.

NGC 5907

NGC 5907 is a spiral galaxy located approximately 50 million light years from Earth. It has an anomalously low metallicity and few detectable giant stars, being apparently composed almost entirely of dwarf stars. It is a member of the NGC 5866 Group. NGC 5907 has long been considered a prototypical example of a warped spiral in relative isolation. The galaxy was discovered in 1788 by William Herschel.

NGC 7331

NGC 7331 is an unbarred spiral galaxy about 40 million light years away in the constellation Pegasus. It was discovered by William Herschel in 1784. NGC 7331 is the brightest member of the NGC 7331 Group of galaxies. The other members of the group are the lenticular or unbarred spirals NGC 7335 and NGC 7336, the barred spiral galaxy NGC 7337 and the elliptical galaxy NGC 7340. In both visible light and infrared photos of the NGC 7331, the core of the galaxy appears to be slightly off-center, with one side of the disk appearing to extend further away from the core than the opposite side. The galaxy is similar in size and structure to the Milky Way, and is often referred to as the Milky Way's twin.

IC 1318 (Detail)

Sadr (γ Cygni) Nebula is the diffuse emission nebula surrounding Sadr or γ Cygni. Sadr lies in the center of Cygnus's cross. The Sadr region is one of the surrounding nebulous regions. It contains many dark nebulae in addition to the emission diffuse nebulae. Shown here is a part of the γ Cygni Nebula.
