Located nearly 70 million light years distant lies the massive 110,000 light year across barred spiral galaxy NGC 1300. It resides in the constellation Eridanus and is part of the 200 galaxy Eridanus Cluster of galaxies. It was discovered by the English astronomer Sir John Frederick William Herschel (Son of Sir Frederick William Herschel) in 1835.
The most beautiful and striking aspect to this galaxy is its incredibly vast central bar spanning the entire central region with thick dust trails leaving material in its wake. Its two elongated, stretched arms contain a great amount of star formation, especially where the arms attach to the ends of the bar. Following the bar in toward its core you will find the central region very bright and with the telltale yellow hue of ancient stars that you find in most galactic cores. The core or nucleus here is also pretty special because; as it is a trait in large barred spiral galaxies, it contains a grand design spiral approximately 3300 light years in diameter. There seems to be no black hole at the center of this galaxy as it is a non-active nucleus.
