This is NGC 4038 and 4039, a pair of galaxies going through a major collision.

The collision started half a billion years ago, and they spent the past few hundred million years sparring with one another. The monstrous gravitational pull tore the galaxies apart and ejected some of the stars and interstellar gas into space. The ejected materials made the long tidal tails reminiscent of an ant’s antennae. The major collision happened near the cores, where a huge amount of dust and gas smashed into each other. This resulted in a stage of rapid star formation. The radiation from the star nurseries ionized the nearby gas clouds, causing them to glow in a pinkish-red; those are the pinkish spots you see in the centre of the image.

Such collision is not uncommon in the universe; most galaxies undergo at least one major collision in their lifetimes. Our own Milky Way is likely to endure the same fate as it collides with the Andromeda Galaxy in several billion years.

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.
