NGC1365 - The Great Barred Spiral Galaxy

NGC1365 is a double-barred spiral galaxy that lies about 75 million light years away from us in the constellation Fornax. There is an inner bar structure that you can just identify in the image tilted up at a roughly 80 degree angle. The outer bar structure is nearly vertical at about a 10 degree angle. It is thought that the inner bar is rotating faster than the outer bar which causes the diagonal shape seen in images. The outer arms of the galaxy complete one orbit every roughly 350 million years.

NGC1365 and other galaxies of its type have been the subject of much research in recent years with new observations indicating that the Milky Way could also be a barred spiral galaxy. These type of galaxies are quite common, with thirds of spiral galaxies being barred according to recent estimates. Understanding barred galaxies can help astronomers understand our own galactic home.

The weather has finally cleared out in Chile, and the seeing is slowly improving. This image was captured over this past dark cycle over a very efficient week of data collection.

Thanks for stopping by.

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.
