The Centaurus A Galaxy (also known as Centaurus A, Peculiar Galaxy NGC 5128, NGC 5128 or Caldwell 77) is the closest active galaxy to Earth, being a radio galaxy. On March 14, 1998 the Hubble telescope offered a close_up view of a turbulent firestorm of star birth along a nearly edge of the galaxy. Centaurus A is part of the M83 Group galaxy cluster.
This galaxy does not fall under Hubble classification as it is both a Spiral and an Elliptical galaxy.

Like most Bristol Engines designs, the Centaurus was based on the mechanicals of an earlier design, in this case the "classic" 5.75 in (146 mm) piston from their original 1918 Jupiter.
The capacity of the Centaurus was increased by placing the pistons in a longer-stroke cylinder, and moving to two rows of nine cylinders instead of two rows of seven.
In fact, the Centaurus did not see any use until near the end of the war, first appearing on an upscaled version of the Vickers Wellington, the Warwick.
