The Leo Triplet

The Leo Triplet (also known as the M66 Group) is a small group of galaxies about 35 million light-years away in the constellation Leo. This galaxy group consists of the spiral galaxies M65, M66, and NGC 3628.The three galaxies are relatively close to each other in space, and their gravitational interaction has caused them to develop some unusual features. For example, M66 has a distorted spiral structure, and NGC 3628 appears to be interacting with both M65 and M66.

M65 (NGC 3623): M65 is a barred spiral galaxy with a diameter of about 100,000 light-years. It has a bright central bulge and two prominent spiral arms. M65 is also known for its active galactic nucleus, which is powered by a supermassive black hole.
M66 (NGC 3627): M66 is a spiral galaxy with a diameter of about 150,000 light-years. It has a distorted spiral structure, with one spiral arm appearing to be more prominent than the other. M66 is also known for its high rate of star formation.
NGC 3628 (The Hamburger Galaxy): NGC 3628 is an edge-on spiral galaxy with a diameter of about 200,000 light-years. It is nicknamed the Hamburger Galaxy because of its distinctive appearance, with a bright central bulge and two dark dust lanes that resemble hamburger buns.

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.
