NGC 3521 - Bubble Galaxy

Located ~40 million light years distant in the direction of Leo, NGC 3521 has several interesting characteristics. It's an obvious flocculent spiral in it's core, but it also has wider spiral structure further out in the arms. The galaxy must have undergone a serious encounter with another galaxy in the not so distant past, as there are huge clouds of stars surrounding the main spiral structure. Could the remains of the interacting galaxy be those outer arms? The galaxy has the nickname "bubble galaxy" due to the extreme edges of the stellar scatter. In this image, that outermost shell of stars is just barely visible. The galaxy is cropped to highlight the internal structures. There are also some nice smaller fuzzies in the field with their own nice structures.

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.
