Laniakea Supercluster
The Laniakea Supercluster (; Hawaiian for "open skies" or "immense heaven") is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies. It was defined in September 2014, when a group of astronomers including R. Brent Tully of the University of Hawaiʻi, Hélène Courtois of the University of Lyon, Yehuda Hoffman of the Hebrew University of Jerusalem, and Daniel Pomarède of CEA Université Paris-Saclay published a new way of defining superclusters according to the relative velocities of galaxies. The new definition of the local supercluster subsumes the prior defined local supercluster, the Virgo Supercluster, as an appendage. Follow-up studies suggest that the Laniakea Supercluster is not gravitationally bound; it will disperse rather than continue to maintain itself as an overdensity relative to surrounding areas. Name The name () means 'immense heaven' in Hawaiian, . The name was suggested by Nawaʻa Napoleon, an assoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Virgo Supercluster
The Virgo Supercluster (Virgo SC) or the Local Supercluster (LSC or LS) is a mass concentration of galaxies containing the Virgo Cluster and Local Group, which itself contains the Milky Way and Andromeda galaxies, as well as others. At least 100 galaxy groups and clusters are located within its diameter of 33 megaparsecs (110 million light-years). The Virgo SC is one of about 10 million superclusters in the observable universe and is in the Pisces–Cetus Supercluster Complex, a galaxy filament. A 2014 study indicates that the Virgo Supercluster is only a lobe of an even greater supercluster, Laniakea, a larger, competing referent of the term Local Supercluster centered on the Great Attractor. Background Beginning with the first large sample of nebulae published by William and John Herschel in 1863, it was known that there is a marked excess of nebular fields in the constellation Virgo (near the north galactic pole). In the 1950s, French–American astronomer Gérard de Vau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NGC 1156
NGC 1156 is a dwarf galaxy, dwarf irregular galaxy, irregular galaxy in the Aries constellation of the type . It is considered a ''Magellanic''-type irregular. The galaxy has a larger than average core, and contains zones of contra-rotating gas. The counter-rotation is thought to be the result of tidal interactions with another gas rich galaxy some time in the past. It has a H II nucleus. The AGES survey has discovered a candidate dark galaxy close to NGC 1156, one of only a few so far found.

NGC 672
NGC 672 is a spiral galaxy in the northern constellation of Triangulum, positioned around 2° to the southwest of the star Alpha Trianguli. The original object designated NGC 672 was discovered by the German-born astronomer William Herschel on 26 October 1786, but this was later cataloged as NGC 614. The object now identified as NGC 672 was discovered by John Herschel on 11 November 1827. ''This link refers to NGC 627, not NGC 672'' This galaxy is located at a distance of approximately from the Milky Way, where it forms an Interacting galaxy, interacting pair with the irregular galaxy IC 1727. In the neutral hydrogen Radio astronomy, radio band, a tidal bridge is observed between the galaxies. NGC 672 appears to be the more massive of the two, and hence IC 1727 shows more distortion from the interaction. Together they form members of a combined group of galaxies that includes NGC 784. The Galaxy morphological classification, morphological classification of NGC 672 is SB(s)cd, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NGC 1058
NGC 1058 is a Seyfert Type 2 galaxy in the NGC 1023 Group, located in the Perseus constellation. It is approximately 27.4 million light years from Earth and has an apparent magnitude of 11.82. It is receding from Earth at , and at relative to the Milky Way.

NGC 891
NGC 891 (also known as Caldwell 23, the Silver Sliver Galaxy, and the Outer Limits Galaxy) is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6, 1784. The galaxy is a member of the NGC 1023 group of galaxies in the Local Supercluster. It has an H II nucleus. The object is visible in small to moderate size telescopes as a faint elongated smear of light with a dust lane visible in larger apertures. In 1999, the Hubble Space Telescope imaged NGC 891 in infrared. In 2005, due to its attractiveness and scientific interest, NGC 891 was selected to be the first light image of the Large Binocular Telescope. In 2012, it was again used as a first light image of the Lowell Discovery Telescope with the Large Monolithic Imager. Supernova SN 1986J was discovered on August 21, 1986 at apparent magnitude 14.

NGC 1023
NGC 1023 is a barred lenticular galaxy, a member of the NGC 1023 group of galaxies in the Local Supercluster. Distance measurements vary from 9.3 to 19.7 million parsecs (30 to 64 million light-years). The supermassive black hole at the core has a mass of . The black hole was discovered by analyzing the dynamics of the galaxy. NGC 1023 is included in Halton Arp's Atlas of Peculiar Galaxies, under the category "Galaxies with Nearby Fragments" under the number 135. NGC 1023 has been estimated to have about 490 globular clusters, consistent with similar early-type galaxies. A number of small galaxies have been found around NGC 1023, the collection of which is labelled the "NGC 1023 Group." NGC 1023 has a satellite galaxy named NGC 1023A, which is a Magellanic spiral galaxy; its globular cluster system is much smaller, estimated to be around six individuals.

NGC 925
NGC 925 Amatha Galaxy is a barred spiral galaxy located about 30 million light-years away in the constellation Triangulum (constellation), Triangulum. The Galaxy morphological classification, morphological classification of this galaxy is SB(s)d, indicating that it has a Barred spiral galaxy#The bars, bar structure and loosely wound spiral arms with no ring. The spiral arm to the south is stronger than the northern arm, with the latter appearing Flocculent spiral galaxy, flocculent and less coherent. The bar is offset from the center of the galaxy and is the site of star formation all along its length. Both of these morphological traits—a dominant spiral arm and the offset bar—are typically characteristics of a Magellanic spiral galaxy. The galaxy is inclined at an angle of 55° to the line of sight along a position angle of 102°. The Amatha galaxy is a member of the NGC 1023 Group, a nearby, gravitationally bound, gravitationally-bound Galaxy groups and clusters, group of gal ...
