NGC 5128, Centaurus A

Centaurus A, also known as NGC 5128 is a very bright elliptical (or possibly lenticular) galaxy that's merging with a spiral galaxy. It's the 5th brightest galaxy in the sky, and is a strong radio source. A 55 million solar mass black hole resides at the core of the galaxy. Wikipedia notes that the x-ray jets of this galaxy are thousands of light years long, and the radio jets are over a million light years long!

One of the most unique galaxies in the sky (IMO), NGC 5128 is an excellent target for astrophotography for those favored with lower latitudes. It's a tough target for us in the northern hemisphere. This object was captured in Arizona at the TAAA CAC dark site over multiple nights in April and May 2021. The maximum elevation angle was 15 degrees.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
