NGC 1511
NGC1511 is a barred spiral galaxy in the constellation of Hydrus. Its velocity with respect to the cosmic microwave background is 1341 ± 5km/s, which corresponds to a Hubble%27s_law, Hubble distance of 19.76 ± 1.39Megaparsec, Mpc (∼64million light-years). It was discovered by United_Kingdom, British astronomer John Herschel on 2 November 1834. One supernova has been observed in NGC1511: SN1935C (type unknown, mag.12.5). The supernova was discovered by Emily Hughes Boyce on 16 August 1935, and was initially thought to be either a supernova, or a nova associated with the Large Magellanic Cloud. It was classified as a nova, and known as either ''HV11970'' or ''Nova Hydri1935''. In September 1988, Sidney_van_den_Bergh, Sidney Van Den Bergh and Martha_Locke_Hazen, Martha L. Hazen concluded definitively that the object was a supernova in NGC1511, and the star was given the designation ''SN1935C''. NGC 1511 Group According to A.M. Garcia, the galaxy NGC1511 is the central memb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New General Catalogue
The ''New General Catalogue of Nebulae and Clusters of Stars'' (abbreviated NGC) is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the ''Index Catalogues'' (abbreviated IC), describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use. The NGC expanded and consolidated the cataloguing work of William and Caroline Herschel, and John Herschel's ''General Catalogue of Nebulae and Clusters of Stars''. Objects south of the celestial equator are catalogued somewhat less thoroughly, but many were included based on observation by John Herschel or James Dunlop. The NGC contained multiple errors, but attempts to eliminate them were made by the ''Revised New General Catalogue'' (RNGC) by Jack W. Sulent ...

Large Magellanic Cloud
The Large Magellanic Cloud (LMC), or Nubecula Major, is a satellite galaxy of the Milky Way. At a distance of around 50 kiloparsecs (≈160,000 light-years), the LMC is the second- or third-closest galaxy to the Milky Way, after the Sagittarius Dwarf Spheroidal (16 kpc) and the possible dwarf irregular galaxy known as the Canis Major Overdensity. Based on the D25 isophote at the B-band (445 nm wavelength of light), the Large Magellanic Cloud is approximately across. It is roughly a hundredth as massive as the Milky WayMagellanic Cloud .

Astronomical Objects Discovered In 1834
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, p ...

IRAS Catalogue Objects
The Infrared Astronomical Satellite (Dutch: ''Infrarood Astronomische Satelliet'') (IRAS) was the first space telescope to perform a survey of the entire night sky at infrared wavelengths. Launched on 25 January 1983, its mission lasted ten months. The telescope was a joint project of the United States (NASA), the Netherlands ( NIVR), and the United Kingdom ( SERC). Over 250,000 infrared sources were observed at 12, 25, 60, and 100 micrometer wavelengths. Support for the processing and analysis of data from IRAS was contributed from the Infrared Processing and Analysis Center at the California Institute of Technology. Currently, the Infrared Science Archive at IPAC holds the IRAS archive. The success of IRAS led to interest in the 1985 Infrared Telescope (IRT) mission on the Space Shuttle, and the planned Shuttle Infrared Telescope Facility which eventually transformed into the Space Infrared Telescope Facility, SIRTF, which in turn was developed into the Spitzer Space Tel ...

List Of NGC Objects (1001–2000)
This is a list of NGC objects 1001–2000 from the New General Catalogue (NGC). The astronomical catalogue is composed mainly of star clusters, nebulae, and galaxies. Other objects in the catalogue can be found in the other subpages of the list of NGC objects. The constellation information in these tables is taken from ''The Complete New General Catalogue and Index Catalogue of Nebulae and Star Clusters by J. L. E. Dreyer'', which was accessed using the "VizieR Service". Galaxy morphological types and objects that are members of the Large Magellanic Cloud are identified using the ''NASA/IPAC Extragalactic Database''.

Lyons Groups Of Galaxies
Lyons Groups of Galaxies (or LGG) is an astronomical catalog of nearby groups of galaxies complete to a limiting apparent magnitude B0=14.0 with a recession velocity smaller than 5,500 km/s. The catalogue was obtained from the Lyon-Meudon Extragalactic Database. Two methods were used in group construction: a percolation method derived from Huchra and Geller and a hierarchical method initiated by R. Brent Tully. The catalog is a synthesized version of the two results. The LGG includes 485 groups and 3,933 member galaxies. See also * Abell catalogue * New General Catalogue * Messier Catalogue The Messier objects are a set of 110 astronomical objects catalogued by the French astronomer Charles Messier in his ''Catalogue des Nébuleuses et des Amas d'Étoiles'' (''Catalogue of Nebulae and Star Clusters'').
