Two thirds of the Leo triplet - M 65 + M 66

In spring 2020, some of the great "classics" were on the to-do list. Among them were the two big "M" of the Leo triplet. Both galaxies are barred spiral galaxies, with Messier 65 looking rather ordinary. Messier 66 shows strong star formation in its two short spiral arms, and has distinct tidal tails at its northern end. However, these are not likely to be from an encounter with NGC 3628, the third representative of the Leo triplet, nor from one with Messier 65, although all three galaxies are similarly distant and thus form a real group. Messier 66 probably "swallowed" at least one larger dwarf galaxy, and we can observe the result of this cosmic meal today.

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.
