The Great Barred Spiral Galaxy of Fornax, NGC 1365

NGC 1365 is a member of the Fornax Galaxy Cluster and lies 75 Mly away. It is a huge
galaxy, extending to 300,000 ly across, i.e. about 3x the size of our Milky Way Galaxy.
Its rotation speed has been determined at 350 My. Astronomers postulate that the prominent
bar plays an important role in the galaxy’s evolution, drawing gas and dust into a star-
forming turmoil. Infra-red astronomy has revealed that the main bar comprises two separate
bars, the second one not extending as far from the centre of the galaxy as the main, visible
one. The existence of the second bar is thought to arise from instabilities within the galaxy
centre. It rotates more rapidly than the main, visible bar.

Note: I have cropped the original frame to improve the size of the galaxy.

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.
