Centaurus A (NGC 5128)

Hi all!

Centaurus A, also called NGC 5128, is a curious massive elliptical galaxy with a supermassive black hole at its heart.
It is located about 12 million light years from Earth in the constellation Centaurus and has the distinction of being the most powerful radio galaxy in the sky.
Indeed it's apparent size of 25' in visible light is about the size of the full moon, but this size reaches almost 20 times the diameter of the full moon in radio waves!
Astronomers believe that the luminous core, strong radio emissions and jet-like details of Centaurus A are produced by the central black hole whose mass is about 100 million times that of the Sun.
The dusty band is probably the unrecognizable remnant of a spiral galaxy being torn apart by the gravitational pull of the giant elliptical galaxy.
Reddish filaments showing halpha emission from the core extend from the galaxy toward the left corner of the image. These are stellar nurseries containing hot young stars.

Bundle Data set bought on Telescope Live, taken with CHI-1 Telescope at El Sauce Observatory, Chile, from april 2020 to july 2021.

Field of view : 32' x 32'
Scale : 0.62"/pixel

L : 18 x 600s
R : 21 x 600s
G : 21 x 600s
B : 19 x 600s

Although Halpha filter exposures would have been ideal to highlight the Halpha jets, im glad i could get them very lightly from the red filter exposures.

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.
