M100

Messier 100 (also known as NGC 4321) is a mag 10.1 face-on spiral galaxy located in the southern part of the constellation of Coma Berenices. It is one of the brightest and largest galaxies in the Virgo cluster and is located approximately 55 million light-years from Earth. The nice edge-on galaxy to the right in my image is NGC 4312. Another small spiral galaxy can be seen to the left of M100 - NGC 4323, and there is an elliptical galaxy, NGC 4328 below M100. IC 783 is at the top, and there are other assorted PGC galaxies spread around this rich area.

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.
