M66 (Arp 16)

This Messier Object, also known as NGC 3627 and Arp 16, is a spiral galaxy located 30 million light years away in the constellation of Leo at a declination of +13 degrees. It is a magnitude 9 galaxy which spans 10 arc-minutes in our apparent view. This corresponds to a diameter of 90,000 light years.

Estimates vary, but I calculate that we are looking at this disk about 30 degrees from edge-on. This is the 35th brightest galaxy in the sky.

I love the colors of this galaxy – the yellow core, the brown dust lanes, blue star clouds, and the pink emission regions. The disk displays a non-symmetric structure, likely due to gravitational interaction with M65 and other nearby galaxies. Of special note is the bluish concentration of stars just below and left of the core.

M66 was selected by Dr. Arp as the 16th Arp object, in the category of Spiral Galaxies - Detached Segments.

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.
