Eridanus Galaxy

==Overview==
The Eridanus Galaxy is classified as a Sc-type galaxy in the Hubble sequence because of its morphology. The galaxy is located in the constellation of Eridanus, hence the name, and it is 39.20 megalight-years away from Earth. Eridanus Galaxy has a diameter of about 118.14 kilolight-years, meaning it is almost identical in size to the Milky Way. The Eridanus Galaxy has no discovered dwarf galaxies orbiting it. The galaxy is the first designated object in the Systematized Collection Of Deep Sky Objects, and it is categorized as SCODSO 1.
==Structure==
Eridanus Galaxy is a face-on spiral galaxy that may be classified as having a grand design, with the spiral arms dominated by bright, young stars, giving it a light-blue appearance, and the dark lanes within the spiral arms absorbing light, giving it a brown-black appearance. The Eridanus Galaxy features many star clusters such as open clusters, which are scattered all over the disk with the spiral arms of the galaxy being the most populated, and globular clusters, which are sprinkled all over the galactic halo but rarely exist inside the galactic disk and are more uncommon than open clusters.
===Spiral arms===
Eridanus Galaxy has a mix of both well-defined spiral arms and flocculent spiral arms spiraling in a counterclockwise direction from the galactic nucleus. The galaxy features two major spiral arms and one minor arm, although the latter is currently unnamed.
===Nucleus===
The galaxy also has a moderately large nucleus and a large galactic bulge, with no signs of a galactic bar existing in the central region. Old stars dominate the region, giving it a yellow-white appearance, and it features a supermassive black hole in the center of the galaxy.
==Supernovae==
The first detected supernova was GSN-SCODSO 1a, with a peak apparent magnitude of about 13.6, and the second supernova, GSN-SCODSO 1b, peaked in brighter than GSN-SCODSO 1a with an apparent magnitude of 10.3. Since then, there have been no detected supernovae.
