The Antennae Galaxies are a pair of interacting galaxies in the constellation Corvus (also known as NGC 4038 and NGC 4039). The galaxies are undergoing a galactic collision and the nuclei of the galaxies are combining to become one larger galaxy. The long tails of gas, stars and dust ejected from the collision resemble an insect’s antennae giving the galaxies their name. Our own Milky Way Galaxy is predicted to collide with the Andromeda Galaxy in a similar collision in the distant future. The galaxies have a relatively young collection of globular clusters that were formed when the two galaxies collided about 600 million years ago. This is a difficult object to image because it is only above the horizon in the spring of each year and the star trails are very dim and require significant exposure. Due to these conditions, images of the galaxies were taken over a two year period and required a total of 16.25 hours of exposure. Specifically, 390 minutes of luminance and 195 minutes of RGB each.

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.
