NGC 1365, also known as the Great Barred Spiral Galaxy,^[3] is a barred spiral galaxy about 56 million light-years away in the constellation Fornax. The core is an oval shape with an apparent size of about 50″ × 40″.^[4] The spiral arms extend in a curve north and south from the ends of the east-west bar and form an almost ring like Z-shaped halo.^[4]

Supernovae 2001du, 1983V, and 1957C were observed in NGC 1365.

Due to recent revisions in the consensus opinion on the shape of our own galaxy,^[5][6] it seems likely that the Milky Way strongly resembles NGC 1365.
