Sculptor
What is Sculptor?
Constellations· Autumn evenings · empty sky east of Fomalhaut. Lacaille's tribute to the sculptor's studio. The south galactic pole lies here, far from the Milky Way, so it is poor in stars but rich in galaxies — chief among them the starburst galaxy NGC 253.

The first dwarf spheroidal galaxy, found in 1937
The Sculptor Dwarf, 290,000 light-years away in the direction of Sculptor, was found by Harlow Shapley on photographic plates in 1937, the first dwarf spheroidal galaxy ever recognised. With a few million stars scattered over several thousand light-years its surface brightness was so low that Shapley, unsure at first whether it was a galaxy or a cluster, called it a new kind of stellar system.
The discovery revealed for the first time that small, faint galaxies might surround the Milky Way in numbers, and more than sixty such satellites are now known. Most of the Sculptor Dwarf's stars are more than ten billion years old, and their motions show that most of the galaxy's mass is dark matter. Beyond the constellation that lies farthest from the Milky Way's band, a new entry in the classification of galaxies began.
The constellation in depth
Sculptor was drawn by Lacaille in the 1750s and originally called the Sculptor's Studio, a long name showing a statue, a pedestal and tools that later cartographers shortened. It lies in the direction of the south galactic pole, away from the Milky Way's glow, so the constellation itself is a sparse patch of fourth-magnitude stars.
What it lacks in stars it makes up in galaxies. NGC 253, the Sculptor Galaxy, is a large spiral about 11 million light-years away undergoing a burst of star formation at its core, bright enough for binoculars; the Cartwheel Galaxy took its ring shape when another galaxy punched through it. The Sculptor dwarf, found in 1938, was the first dwarf elliptical galaxy discovered. Several of these galaxies are within reach of a modest amateur telescope.
At declinations of −25° to −39° it is visible from Korea, low in the south on October and November evenings: look east of bright Fomalhaut and south of Cetus. In the Sky view, set Seoul on a November night and look south, or choose a southern city. With the lines on, its sparse stars connect into a recognisable figure.
