Centaurus A : amateur data for the visible, professional data for the invisible

We're delighted to bring you a slightly more experimental image.

We present NGC 5128 (or Centaurus A) mixing the visible spectrum of light with our amateur data, and different spectra outside the visible with professional data.

Centaurus A, a lenticular galaxy, is the fifth-brightest galaxy in the sky and is located in the constellation Centaurus, around 12 million light-years from Earth.

Long exposures in Hɑ and [Oiii] revealed jets from the galaxy's supermassive black hole as rarely seen with this resolution. These extend very far from the galaxy, over more than a million light-years, just phenomenal!

This combination of images with these narrow-band filters and the use of conventional RGB filters highlights the galaxy in the visible spectrum.

But deep-sky objects can also be studied outside the visible spectrum. Professional telescopes and satellites have studied this galaxy in different spectra: X-rays and radio, for example.

These data are publicly accessible and can be found on the various websites of the space agencies or observatories that produce them.

Here we present an image mixing our data with that of the Chandra space telescope for X-rays and the Very Large Array observatory for radio data.

X-rays are shown here in violet and radio waves in darker blue.
The latter remain unobtrusive, as they are partly masked by the X-ray data.

The result is a complete image mixing the visible and invisible, the amateur and the professional, to give a complete vision of this galaxy beyond what the human eye can perceive.

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.
