Backward Galaxy

Introduction
Backward Galaxy, also known as NGC 4622 or PGC 42701, is a unbarred spiral galaxy located within The Centaurus Constellation. An unbarred spiral galaxy is a spiral galaxy without a central bar. Backward Galaxy has a prominent ring structure. Backward Galaxy is located 111 Million Light Years from Earth. 
Profile of Backward Galaxy
The Backwards Galaxy was discovered by a team of scientist Ron Buta and Gene Byrd of The University of Alabama Tuscaloosa and Tarsh Freeman of Bevill State Community College in Alabama. Backward is a Galaxy with leading spiral arms. In spiral galaxies, spiral arms were thought to trail; the tips of the spiral arms winding away from the center of the galaxy in the direction of the disks orbital rotation. In The Backward Galaxy, the outer arms are leading spiral arms and  the tips of the spiral arms point towards the direction of disk rotation. This may be the result of a gravitational interaction between NGC 4622 and another galaxy or the result of a merger between Backward and something smaller. It was originally believed that the inner spiral arm was a leading arm, the observations that established that the outer arms were leading also established that the inner arm was trailing. This however met with skepticism in part because they contradicted conventional wisdom with a quote being “So you’re the backward astronomers who found the backward galaxy.” And that is how NGC 4622 received the name Backward Galaxy.
