NGC 346 is a young [4] open cluster of stars with associated nebula located in the Small Magellanic Cloud (SMC) that appears in the southern constellation of Tucana.It was discovered August 1, 1826 by Scottish astronomer James Dunlop.
NGC 290 is an open cluster of stars in the southern constellation of Tucana.This cluster was discovered September 5, 1826, by Scottish astronomer James Dunlop. [7] It lies some 200,000 light years away from the Sun in the Small Magellanic Cloud galaxy.
The Small Magellanic Cloud (SMC) is a dwarf galaxy near the Milky Way. [5] Classified as a dwarf irregular galaxy , the SMC has a D 25 isophotal diameter of about 5.78 kiloparsecs (18,900 light-years), [ 1 ] [ 3 ] and contains several hundred million stars. [ 5 ]
This makes it feasible to use them as indicators of distance. Recently, they have been used to give direct distance estimates to the Large Magellanic Cloud (LMC), Small Magellanic Cloud (SMC), Andromeda Galaxy and Triangulum Galaxy. Eclipsing binaries offer a direct method to gauge the distance to galaxies to a new improved 5% level of accuracy ...
Large Magellanic Cloud: antiquity–1994: 0.163 Mly This is the upper bound, as it is the nearest galaxy observable with the naked eye. [citation needed] Small Magellanic Cloud: 1913–1914: 0.197 Mly This was the first intergalactic distance measured. In 1913, Ejnar Hertzsprung measures the distance to SMC using Cepheid variables. In 1914, he ...
At a distance of about 180,000 light years (55,000 parsecs), it is located within the Small Magellanic Cloud. [2] It has a mass of about 3.0 × 10 4 M ☉, and a luminosity of about 8.0 × 10 4 L ☉. [3] NGC 411 was imaged by the Hubble Space Telescope in 2013, showing an abundance of stars ranging from blue to red. [6]
NGC 602c is a looser grouping 11 arc-minutes to the NE, which includes the WO star AB8. [9] NGC 602 includes many young O and B stars and young stellar objects, with few evolved stars. [10] Ionisation in the nebula is dominated by Sk 183, an extremely hot O3 main sequence star visible as the bright isolated star at the centre of the Hubble ...
[11] [12] In the 1756 star map of the French astronomer Lacaille, they are designated as le Grand Nuage and le Petit Nuage ("the Large Cloud" and "the Small Cloud"). [ 13 ] [ 14 ] John Herschel studied the Magellanic Clouds from South Africa, writing an 1847 report detailing 919 objects in the Large Magellanic Cloud and 244 objects in the Small ...
