NGC 4689

This object is a spiral galaxy located 50 million light years away in the constellation of Coma Berenices at a declination of +14 degrees. This magnitude 11 galaxy spans 4 arc-minutes in our apparent view, which corresponds to a diameter of 60,000 light years. The galaxy appears to us about 35 degrees from face-on.

This object is classified as a low surface brightness galaxy. All images of this object appear to be a bit fuzzy to me, as if this galaxy is hiding behind a cloud of dust.

I find the structure of this galaxy to be fascinating – two faint concentric “rings”, one around the inner bright section and one around the dimmer mid-region. These 2 “rings” are similar in shape – not really rings but more like disturbed hexagons. They look to me to be Vorontsov-Velyaminov rows, which is unusual here because there is not a defined arm structure. Several star clusters are seen in the disk, which has a pink tint to it due to star formation I assume.

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.
