NGC 3953

This object is a barred spiral galaxy located 50 million light years away in the constellation of Ursa Major at a declination of +52 degrees. It has a magnitude of 10.1 and a surface brightness of 13.1. The galaxy spans 6 arc-minutes, which corresponds to a diameter of 90,000 light years. Our view is more edge-on than face-on, being inclined 30 degrees from edge on.

This is a beautiful galaxy, with tremendous color and numerous bright blue star clusters. Two interesting features stand out to me, both best seen in the full resolution view. I couldn't find an explanation of either feature in the literature. Directly below the core on the outer edge of the galaxy is a nearly ring-shaped feature that looks like a star cluster, but I have never seen one in this shape before. On the opposite side of the core, above halfway between the core and the top of the page, is what looks like a round dwarf galaxy immediate adjacent to a small bright orange star. Both of these features are visually appealing to me.

Several tiny galaxies are visible in the nearby background.

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.
