NGC 1300, a barred spiral galaxy, is about 69 million light years away in Eridanus. At 130,000 light years in diameter, it is slightly larger than our Milky Way. It is considered a prototypical barred spiral galaxy. The central core also exhibits a grand-design spiral structure, a feature only present in large-scale barred galaxies.
