OBJECT DESCRIPTION

NGC 5128 is the closest and bigger elliptical galaxy to our solar system and optically one of the brightest of our night sky. It has a particular structure because of it prominent rotational star and dust disc with a dramatic dust dark region that cross the galactic centre.

Centaurus A has a diameter of 60,000 light years and there is evidence that Centaurus A is the result of the collision of two normal galaxies. Centaurus A emits 1000 times more radio energy than our Milky Way. This is done in a bidirectional way generation big lobules that spans 800,000 light yeas in the intergalactic space. It was discovered by James Dunlop in August 1826
