This image could also be named "The Dancing Galaxies" as actually these interacting galaxies are absorbed in a cosmic dance. NGC 4038 (left) and NGC 4039 (right) started their approach to each other under the influence of their gravitational forces some 900 Mio years ago. 600 Mio years ago the two spiral galaxies passed through each other, releasing stars, gas and dust (the antennae like arcs) about 300 Mio years ago by tidal forces.
In 400 Mio years they will probably merge to one huge elliptical galaxy. This scenario is probably very similar to what Milky Way and Andromeda Galaxie will perform in the future.
The Antennae Galaxies are 45 Mio LY from us.

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.
