Stephan's Quintet - Galaxy mergers

I present a new look at Stephan's Quintet galaxies, imaged by Hubble Space Telescope and processed by myself, Roi Levi.

These five galaxies are “Stephen’s Quintet”, also known as Hickson Compact Group 92, and were photographed from the new Wide Field Camera 3 (WFC3) aboard NASA's Hubble Space Telescope.

Pictured are, clockwise from upper left, NGC 7320, NGC 7319, NGC 7318a, NGC 7318b, and NGC 7317.

The two galaxies in the center, NGC 7318a and NGC 7318b are galaxies in the merging process and they will eventually become one galaxy.

Galaxy mergers can occur when two or more galaxies collide and these are now in the most violent type of galaxy interaction. The gravitational interactions between galaxies and the friction between the gases and dust majorly effects the galaxies involved in the merge.

It is most likely that the whole group of five will merge with each other and form one galaxy over time.

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.
