The Sculptor Dwarf Galaxy (also called the Sculptor Dwarf Elliptical Galaxy or the Sculptor Dwarf Spheroidal Galaxy) is a dwarf spheroidal galaxy that is a satellite of the Milky Way. The galaxy lies within the constellation Sculptor. It was discovered in 1937 by Harlow Shapley using the 24-inch Bruce refractor at Boyden Observatory.[4][5] The galaxy is located about 290,000 light-years away from the Solar System. The Sculptor Dwarf contains only 4 percent of the carbon and other heavy elements in our own galaxy, the Milky Way, making it similar to primitive galaxies seen at the edge of the universe.[6]
Metallicity
The metallicity of Sculptor dwarf appears to be broken up into two distinct groups, one with [Fe/H] = -2.3 and the other with [Fe/H] = -1.5.[7] Similar to many of the other Local Group galaxies, the older metal-poor segment appears more extended than the younger metal-rich segment.[8]
