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 wide curve north and south from the ends of the east-west bar and form an almost ring like Z-shaped halo.[4] The central mass in active galactic nucleus rotate close to relativistic limit (the dimensionless spin parameter is larger than 0.84).[5]

Supernovae 2012fr, 2001du, 1983V, and 1957C were observed in NGC 1365.
