NGC 1 and NGC 2 as an optical double. NGC 2 is located about 345 million light-years from the Solar System, with a magnitude of +14.2, while the distance to NGC 1 is 210 million light-years. Although visually close in the sky, NGC 1 and NGC 2 are at very different distances; were they stars, they would be referred to as an "optical double" as ...
Messier 2 or M2 (also designated NGC 7089) is a globular cluster in the constellation Aquarius, five degrees north of the star Beta Aquarii. It was discovered by Jean-Dominique Maraldi in 1746, and is one of the largest known globular clusters.
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.

Messier 110, or M110, also known as NGC 205, is a dwarf elliptical galaxy that is a satellite of the Andromeda Galaxy in the Local Group. [ 9 ] Early observational history
The galaxy's strange morphology is generally recognized as the result of a merger between two smaller galaxies.

NGC 4676, or the Mice Galaxies, are two spiral galaxies in the constellation Coma Berenices. About 290 million light-years distant, [ 2 ] they have begun the process of colliding and merging. Their "mice" name refers to the long tails produced by tidal action —the relative difference between gravitational pulls on the near and far parts of ...
It is located 130,000 light-years (40 kpc) [3] from the Andromeda Galaxy's galactic core, and is the brightest [3] (by absolute magnitude) globular cluster in the Local Group, with an absolute visual magnitude of −10.94 and the luminosity of 2 million Suns. [4] It has an apparent magnitude of 13.81 in V band.
Astronomers theorize that a collision with a smaller companion galaxy near the core of the main galaxy could have led to the unusual spiral structure. [7] NGC 5253, a peculiar irregular galaxy, is located near the border with Hydra and M83, with which it likely had a close gravitational interaction 1–2 billion years ago. This may have sparked ...
