A low level of heavy elements thus indicates that the average age of the stars in the Sculptor Dwarf Galaxy is high. Copyright © 1998 - 2020 SciTechDaily. The Sculptor Dwarf Galaxy is one of the Milky Way’s neighbouring dwarf galaxies. Despite its proximity, the galaxy was only discovered in 1937, as its stars are faint and spread thinly across the sky. These galactic hitchhikers are located close by in the Milky Way’s extensive halo, a spherical region extending far beyond our galaxy’s spiral arms. All Rights Reserved. Right ascension – analogous to longitude – is one component of an object's position. By European Southern Observatory 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. The Sculptor Dwarf Galaxy is about 300,000 light-years away, and is notable because among other things it contains many stars that are lacking in heavy elements like iron.
