NGC 3521, The Bubble Galaxy

NGC 3521 - The so-called "Bubble galaxy" is a spiral galaxy about 50,000 light years in diameter, located just 26.2 million light years from Earth in the constellation Leo (Leo), while that it moves away from us at about 801 kilometers per second. .

The galaxy has a morphological classification of SAB (rs) bc, which indicates that it is a spiral galaxy with a trace of bar structure (SAB), a weak internal ring (rs) and an arm structure. . moderately to weakly wound (bc).

The multiple spiral arms of the NGC 3521 are somewhat uneven and irregular, making it a so-called flocculent spiral galaxy. These galaxies have discontinuous "fluffy" spiral arms that differ from the well-defined arms of large-design spiral galaxies. About 30 percent of all spiral galaxies discovered to date are flocculent.

The image reveals evidence of one or more previous fusions with dwarf galaxies that left discernible substructures, like an almost spherical cloud of debris visible almost all around. This represents shells of debris belonging to an umbrella-like structure.

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.
