SN 2005cs was a supernova in the spiral galaxy M51, [3] known as the Whirlpool Galaxy. It was a type II-P core-collapse supernova, discovered June 28, 2005 by Wolfgang Kloehr, a German amateur astronomer. [5] The event was positioned at an offset of 15″ west and 78″ south of the galactic nucleus of M51. [2]
The M51 Group is a group of galaxies located in Canes Venatici.The group is named after the brightest galaxy in the group, the Whirlpool Galaxy (M51A). Other notable members include the companion galaxy to the Whirlpool Galaxy and the Sunflower Galaxy (M63).
The Whirlpool Galaxy, also known as Messier 51a (M51a) or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. [ 6 ] [ 7 ] [ 8 ] It lies in the constellation Canes Venatici , and was the first galaxy to be classified as a spiral galaxy. [ 9 ]

NGC 5195 (also known as Messier 51b or M51b) is a dwarf galaxy that is interacting with the Whirlpool Galaxy (also known as M51a or NGC 5194). Both galaxies are located approximately 25 million light-years away in the constellation Canes Venatici. Together, the two galaxies are one of the most famous interacting galaxy pairs.
UGC 4881, the brighter, is a peculiar spiral galaxy. It has been heavily documented by the Hubble Space Telescope , and is cataloged in the Atlas of Peculiar Galaxies . [ 2 ] [ 3 ]
The Galactic Center is the barycenter of the Milky Way and a corresponding point on the rotational axis of the galaxy. [ 1 ] [ 2 ] Its central massive object is a supermassive black hole of about 4 million solar masses , which is called Sagittarius A* , [ 3 ] [ 4 ] [ 5 ] a compact radio source which is almost exactly at the galactic rotational ...
