Sculptor Group
The Sculptor Group is a loose group of galaxies visible near the south galactic pole. The group is one of the closest groups of galaxies to the Local Group; the distance to the center of the group from the Milky Way is approximately . The Sculptor Galaxy (NGC 253) and a few other galaxies form a gravitationally-bound core in the center of this group. A few other galaxies at the periphery may be associated with the group but may not be gravitationally bound. Because most of the galaxies in this group are actually weakly gravitationally bound, the group may also be described as a filament. It is considered to be at an early stage of evolution in which galaxies are still falling into the group along filamentary structures. Members The table below lists galaxies that have been identified as associated with the Sculptor Galaxy (and hence associated with the group) by I. D. Karachentsev and collaborators. The object names used in the above table differ from the names used by Kar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Redshift
In physics, a redshift is an increase in the wavelength, and corresponding decrease in the frequency and photon energy, of electromagnetic radiation (such as light). The opposite change, a decrease in wavelength and increase in frequency and energy, is known as a #Blueshift, blueshift. The terms derive from the colours red and blue which form the extremes of the Visible spectrum, visible light spectrum. Three forms of redshift occur in astronomy and cosmology: Doppler effect, Doppler redshifts due to the relative motions of radiation sources, gravitational redshift as radiation escapes from gravitational potentials, and cosmological redshifts of all light sources proportional to their distances from Earth, a fact known as Hubble's law that implies the expansion of the universe, universe is expanding. All redshifts can be understood under the umbrella of Frame of reference, frame transformation laws. Gravitational waves, which also travel at Speed of light, the speed of light, a ...

UGCA 15
The Uppsala General Catalogue of Galaxies (UGC) is a catalogue of 12,921 galaxies visible from the northern hemisphere. It was first published in 1973. The catalogue includes essentially all galaxies north of declination −02°30′ and to a limiting diameter of 1.0 arcminute or to a limiting apparent magnitude of 14.5. The primary source of data is the blue prints of the Palomar Observatory Sky Survey (POSS). It also includes galaxies smaller than 1.0 arcminute in diameter but brighter than 14.5 magnitude from the Catalogue of Galaxies and of Clusters of Galaxies (CGCG). The catalogue contains descriptions of the galaxies and their surrounding areas, plus conventional system classifications and position angles for flattened galaxies. Galaxy diameters are included and the classifications and descriptions are given in such a way as to provide as accurate an account as possible of the appearance of the galaxies on the prints. The accuracy of coordinates is only what is necessary f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PGC 2933
PGC or LEDA 2933 is a faint dwarf irregular galaxy in the Sculptor Group. It can be seen in the southern constellation Phoenix. According to measurements, the galaxy is located 11.15 million light-years away. Because it is situated in the Sculptor Group, it is one of the closest galaxies to the Milky Way The Milky Way or Milky Way Galaxy is the galaxy that includes the Solar System, with the name describing the #Appearance, galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars in other arms of the galax .... It is obscured by a few brighter stars and galaxies (the brightest of them on the right side of the photo is 1425 light-years away from the Solar System).

NGC 7793
NGC 7793 is a flocculent spiral galaxy in the southern constellation of Sculptor. It was discovered on July 14, 1826, by Scottish astronomer James Dunlop. The galaxy is located at a distance of million light years and is receding with a heliocentric radial velocity of . NGC 7793 is one of the five brightest galaxies within the Sculptor Group. The morphological class of NGC 7793 is SA(s)d, indicating it is unbarred spiral galaxy (SA) with no inner ring structure (s) and the arms are loosely wound and disorganized (d).

NGC 625
NGC 625 is a dwarf barred spiral galaxy about 12.7 Mly away in the constellation Phoenix. It was discovered on 2 September 1826 by Scottish astronomer James Dunlop. NGC 625 is a member of the Sculptor Group. NGC 625 has an active galactic nucleus, i.e. a compact region at the center that emits a significant amount of energy across the electromagnetic spectrum, with characteristics indicating that this luminosity is not produced by the stars.

NGC 247
NGC 247 (also known as Caldwell 62 and commonly known as the Claw Galaxy) is an intermediate spiral galaxy about 11.1 Mly away in the constellation Cetus. This distance was confirmed in late February 2011. Previous measurements showed that the galaxy was about 12.2 Mly away, but this was proved to be wrong. NGC 247 is a member of the Sculptor Group, and is 70 000 light years in diameter. NGC 247 has an unusually large void on one side of its spiral disk. This void contains some older, redder stars but no younger, bluer stars. Nearby galaxies and galaxy group information NGC 247 is one of several galaxies that is gravitationally bound to the Sculptor Galaxy (NGC 253). These galaxies form a small core in the center of the Sculptor Group, which is one of the nearest groups of galaxies to the Milky Way. Most other galaxies associated with the Sculptor Group are only weakly gravitationally bound to this core. Burbidge's Chain In 1963, Geoffrey Burbidge and Margaret Burbidge ...
