Leo Triplet 2024 (framoro)

Leo Triplet 2024

The Leo Triplet is made up of the interacting galaxies M65, M66 and NGC 3628.
M65 is 22 million LY away from us; its apparent magnitude is 9.3. It is a spiral galaxy, although it is seen from a very inclined angle, so it can be observed almost edge-on; the spiral arms are crossed by a system of dark dust, with star formation phenomena. Its real diameter would be 70000 LY and its mass equal to 85 billion solar masses.
With an apparent magnitude of 8.9, M66 is the brightest member of the Leo Triplet. The galaxy, also with a spiral morphology, weakly barred, is 35 million LY from us and has a radius of approximately 50,000 LY. It is seen at a less inclined angle than its companion M65, and thanks to its arrangement it is possible to observe the two arms of the spiral wrapping around the nucleus.
NGC 3628, also called the Hamburger Galaxy, is an unbarred spiral galaxy visible almost perfectly edge-on. This is the third companion of the Leo Triplet. This galaxy, which has a diameter of 100,000 LY and is 35 million LY away from the Solar System, is less luminous than its companions but is very large, with a long luminous spindle that runs through its entire length. Its most obvious features are the wide, dark band of dust located along the outer edge of its spiral arms, which cuts the galaxy as viewed from Earth, and the so-called "tail", made up of stars and gas that the galaxy has lost over several billion years due to gravitational interactions with its "neighborhood".
Even very distant galaxies are visible in the image: IC2725 at some 1165 MLY, IC2729 at 1089 MLY and IC2722, partially visible in the upper left part of the image, which is a 1000 MLY distant galaxy trio.

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.
