APOD 4.2

Centaurus A (April 4, 2012)
This is an image of the galaxy Centaurus A, the closest active galaxy to Earth.  It's about 11 million light-years away and spans over 60,000 light-years.  This elliptical galaxy was most likely formed from the collision of two other galaxies.  At the center of the galaxy there is a black hole with a billion times the mass of the sun that is consuming cosmic debris.
