NGC 1073 is a barred spiral galaxy in the constellation Cetus. The galaxy is estimated to be about 55 million light years from Earth, possess a disk spanning an estimated 80,000 light years in diameter, and likely contains a type of active core, called an HII nucleus.[2][3] It was discovered by German-British astronomer William Herschel on 9 October 1785.[4]
NGC 1073 is similar to the Milky Way only in their shared possession of a galactic bar. NGC 1073, however, does not possess the well-defined symmetrical arm structure the Milky Way exhibits, and retains a central bar larger than our home galaxy's.[5] NGC 1073 can be viewed with a mid-sized telescope in rural, dark skies.
Supernova
One supernova has been observed in NGC 1073: SN 1962L (Type Ic, mag. 13.9) was discovered by Leonida Rosino on 23 November 1962,[6] and independently by Enrique Chavira and Guillermo Haro.[7]
