NGC 1365 (Great Barred Spiral Galaxy)
NGC 1365 (also known as Great Barred Spiral Galaxy) is a spiral galaxy in the constellation Fornax. It has an apparent visual magnitude of 10.3 and its angular diameter is 11.2 × 6.2 arc-minutes. NGC 1365 lies at an estimated distance of 56.2 million light-years. It is a dominant member of the well-studied Fornax galaxy cluster. This image clearly shows the intense star forming regions at the ends of the bar and along the spiral arms, and details of dust lanes cutting across the galaxy's bright core. At the core lies a supermassive black hole. Astronomers think NGC 1365's prominent bar plays a crucial role in the galaxy's evolution, drawing gas and dust into a star-forming maelstrom and ultimately feeding material into the central black hole.
