Centaurus A - NGC 5128 - Caldwell 77

Located in the constellation Centaurus, visible from the southern hemispheres, it is approximately 11-13 million light-years away, at 60,000 ly. This photo has 10 minutes of exposure and was taken on May 17, 2023 - 23:32-23:48 (UTC-3) from Brazil. Next version I would be great to increase exposure time and a probably a longer focal length telescope to try to capture more details. Centaurus A is a very interesting combination of different types of galaxies with four large radio sources (ref. Laustsen et al 1987) characteristics studied by astronomers, since one hypothesis is the result of a “slow” collision of two galaxies, one of elliptical nature (Class SO) with a vast halo of stars and the other that is represented by the dark disk composed of dust and stars similar to a spiral galaxy like ours.

Localizado na constelação do Centauro, visível nos hemisférios do sul, está aproximadamente 11-13 milhões de anos-luz de distância, com 60.000 . Esta foto possui 10 minutos de exposição foi obtido em 17 de maio de 2023 - 23:32-23:48 (UTC-3) do Brasil. Próxima versão gostaria fazer maior tempo de exposição e com um telescópio de maior distancia focal para tentar capturar mais detalhes. Centauro A é uma combinação muito interessante de diferentes tipos de galáxias com quatro grandes fontes de radio (ref. Laustsen et ali 1987) características estudadas pelos astrônomos, uma vez que uma hipótese é o resultado de uma colisão “lenta” de duas galáxias, uma de natureza elíptica (classe SO) com um vasto halo de estrelas e a outra que é representada pelo disco escuro composto por poeira e estrelas semelhante a uma galáxia espiral como a nossa.

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.
