NGC5128 - Centaurus A

Centaurus A has been studied extensively by astronomers given that it is a strong source of radio waves and x-ray transmissions. It is classified as an elliptical galaxy and is thought to have been formed from a collision with a smaller spiral galaxy. There is a supermassive black hole at the centre of the galaxy that is the source of the x-ray transmissions.

The appearance of NGC 5128 is quite distinctive and it is often referred to as the 'hamburger galaxy'. It is a bright object that makes for a nice imaging target. The original name of Centaurus A for this galaxy dates back to the cataloging of sources of radio transmissions. Centaurus A was the first bright source of radio emissions discovered in Centaurus.

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.
