NGC 5448

This spiral galaxy is located 110 million light years away in the constellation of Ursa Major at a declination of +49 degrees. It spans 4 arc-minutes in our apparent view. This corresponds to a Milky Way size diameter of 120,000 light years.

The structure of this galaxy is interesting with 2 pseudo-rings, one around the mid-region and one around the outer edge of the disk. Even at its distance away from us, small star clouds are apparent especially in the mid-region area. The central yellow area contrasts with a subtle blue in the outer disk.

The most fascinating part of this galaxy to me are the two similar and faint arm / star stream features that seem to "cross" the rings. On the left side, a feature is seen which connects the outer ring to the inner ring. On the right side, a similar feature connects the inner ring to the core, and it very faintly continues to the outer ring as well. Our view of the disk only 20 degrees from edge-on makes it difficult to understand what is happening here.

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.
