Porpoise Galaxy, also known as NGC 2936, UGC 5130 and MCG+01-25-006, is an Interacting Spiral Galaxy located inside The Hydra Constellation. An Interacting Galaxy is a galaxy that has a gravitational field that disrupts another galaxies gravitational field and vice versa. Interacting Galaxies could also be called Colliding Galaxies. Porpoise is located 352 Million Light Years from Earth. NGC 2936 gets it's named 'Porpoise Galaxy' because of its similarity to the sea animal, The Porpoise, which is similar to The Sea Animal, The Dolphin.
Profile of The Porpoise Galaxy
The Porpoise Galaxy was discovered on March 3rd, 1864 by German Astronomer Albert Marth. The Porpoise Galaxy is Interacting or Colliding with an Elliptical Galaxy known as NGC 2937. German Astronomer Albert Marth actually discovered both these two galaxies, NGC 2936 and NGC 2937, at the same time of observation. The Porpoise Galaxy because it became an Interacting Spiral Galaxy, was just a regular Flat Spiral Galaxy. Until, the two gravitational fields of both NGC 2936 and NGC 2937, started interacting with one another; and the Porpoise Galaxy would never be the same. NGC 2936's shape started morphing from a flat shape to the shape that we see today, the shape of a Porpoise. One day the NGC 2936 and NGC 2937 will collide completely and become a new galaxy, what it will look like is for the future to know.
