NGC 4450

This object is a spiral galaxy located 50 million light years away in the constellation of Coma Berenices at a declination of +17 degrees. This magnitude 10 galaxy spans 4.3 arc-minutes in our apparent view, which corresponds to a diameter of 65,000 light years.

This galaxy has an occluded disk without much structure except for the dark dust lanes which spiral in to the bright core. It is classified as an "anemic galaxy", which means that it has low contrast between its spiral arms and its disk.

But despite this label, I like the subtle and unusual structure of the disk. The upper left and lower right regions of the disk look darker. I assume this is because the star density in these areas is less, which I find hard to understand.

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.
