Centaurus A Extreme Deep Field - 120 Hours of Exposure!
Centaurus A (or Cen A to its friends) is a nearby galaxy with a weird history. It’s an elliptical galaxy—a giant cotton ball collection of stars—that was, until recently, two separate galaxies that collided and merged. It has a huge dust lane cutting right across the middle, a sure-fire sign that the galaxy was the result of a cosmic train wreck.
The features you can see are astonishing. The galaxy has a massive central black hole, and is actively gobbling down matter (which is why it’s called an active galaxy). You can’t see the black hole itself, but blasting away from the black hole at a good fraction of the speed of light are a pair of jets, beams of matter and energy heading in opposite direction.
The detail is amazing, and you really seriously want to embiggen it
