This glorious spiral galaxy is known as NGC 24, measures some 40,000 light-years across and lies about 25 million light-years away in the southern constellation of Sculptor. However, there may be more to this picture than first meets the eye: 80 percent of NGC 24’s mass is thought to be held within an invisible dark matter halo.
The Sculptor Dwarf Galaxy, pictured in this new image from ESO’s La Silla Observatory, is a close neighbour of the Milky Way. This galaxy is much smaller and older than ours, making it a valuable subject for studying both star and galaxy formation in the early universe. However, due to its faintness, studying this object is no easy task.
