It is a small group of galaxies located in the constellation Leo, located 30-35 million light-years away from Earth. This group is one of the most popular targets for both astrophotography and visual observations, January-April being the best time to image these galaxies.
As a brief individual presentation, these 3 galaxies are as follows:
- NGC 3628 (the one on the left), also known as the Hamburger Galaxy, due to its shape as we see it - is about 35 million light-years away and is surrounded by a cloud of stellar dust that hides most of the galaxy.
- Messier 65 (top right in the attached image) - is the smallest of the 3 galaxies and also the closest to Earth ("only" 31 million light-years away).
- Messier 66 (the one on the right) - is the brightest galaxy in the group and is 35 million light-years away. According to specialists, this galaxy is the largest in the group, with a diameter of about 95,000 light-years, almost as big as our galaxy.

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.
