Centaurus A - NGC 5128
Date image was taken: June 11, 2023
Image Description and Details : Centaurus A (also known as NGC 5128 or Caldwell 77) is a galaxy in the constellation of Centaurus. The unusual morphology of the galaxy is indicative of the merger of two galaxies resulting in intense starburst activity. The shredding dust lane is remarkable evidence of this and the image shows shell upon concentric shell of stars. The central region is bright in Ha and the Continuum Mapping process was used, subtracting the red from the Ha to leave its true signal. Ha permeates the dust lane and core and is reflected in the image by the red/ pink warmth there. The relativistic jets from the supermassive black hole at the centre of the galaxy, excite hydrogen clouds and result in an Ha glow emanating to the north (upwards).
