Leo Triplet - M65, M66 and NGC 3628

M65, M66 and NGC 3628 are part of a group of galaxies similar to our Local Group, although its components are in greater interaction with each other.

M65 (also known as NGC 3623) is a spiral galaxy discovered by Pierre Méchain in 1780, 22 million light years away from us and of apparent magnitude 9,3. Its spiral arms are crossed by a system of dark dust, in which very bright blue stars are evident in the high resolution images, a sign of a star formation. Its real diameter would be 70000 light years and its mass equal to 85 billion solar masses.

M66 (also known as NGC 3627) is a spiral galaxy discovered by Pierre Méchain in 1780 and is the brightest member of the Triplet with an apparent magnitude of 8,9. The galaxy is 35 million light years away from us and has a radius of about 50000 light years.

NGC 3628 (also known as the Hamburger Galaxy) is the least bright member of the Triplet but the largest, of apparent magnitude 10,4. It is an unbarred spiral galaxy about 35 million light years away from us discovered by William Herschel in 1784. Its most striking feature is the wide dark band of dust located along the outer edge of its spiral arms.

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.
