The NGC 1 and 2 pair are not physically related. NGC 1 lies at a distance of ~200 million l.y. with NGC 2 at roughly 320 million l.y. [5] The initial observers missed NGC 2, which is much fainter. NGC 1 appears to be quite close to NGC 2, in reality however, the two objects are far apart and unrelated. NGC 2 was first observed as a "companion ...
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. List of NGC objects (1–1000) List of NGC objects (1001–2000) List of NGC objects (2001–3000)

z = 2.554 (11.1 Gly) Observations from ALMA has shown that the lensed galaxy 9io9 contains a magnetic field. Planet: SWEEPS-11 / SWEEPS-04 (27,710 ly) [96] An analysis of the lightcurve of the microlensing event PA-99-N2 suggests the presence of a planet orbiting a star in the Andromeda Galaxy. [97]
The radial velocity of GSC 03549–02811 over time, caused by the presence of TrES-2 b. TrES-2b was discovered on August 21, 2006 by the Trans-Atlantic Exoplanet Survey (TrES) by detecting the transit of the planet across its parent star using Sleuth (Palomar Observatory, California) and PSST (Lowell Observatory, Arizona), part of the TrES network of 10–cm telescopes.
The inner and outer edges of this belt are close to 4:1 and 2:1 resonances with the planet. [8] A broad zone of cold dust (T ≈ 45 K) with a sharp inner edge orbiting just outside the outermost planet (b). The inner edge of this belt is approximately in 3:2 resonance with said planet, similar to Neptune and the Kuiper belt. [8]
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 ...
