Leo Trio

Galaxies in Leo. A picture 1.3 degrees across of our spring night sky.

Here's one of three images I took on the nights of 3-4 and 3-5 2016 (last weekend) from Haleakala summit (Haleakala amateur astronomers facility, Henry Weiland, Alex Dzierba, Steve McGee, Stanley Truitt, thanks you guys, Henry, wish you were there man).

On the upper left is Galaxy ngc 3593. On the lower right you can see the Leo trio.

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 (wiki).

An interesting feature showed up on the images. It is a faint tidal tail coming from ngc 3628 (Galaxy at the bottom right of the image). There are many galaxies with these tails. This tail, is a string of stars that extends approx 300 thousand light years from its host! Tidal tails are created from interactions with other galaxies.

Also if you look very closely you can see more than three dozen small, faint and fuzzy galaxies littered throughout the field.

Aloha.

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.
