Arp 87

This tiny Arp object, also known as NGC 3808, is two interacting galaxies located 300 million light years away in the constellation of Leo. The apparent size of each galaxy is less than one minute.

I love the bridge of stars between these two galaxies and how it spirals around the top galaxy into a faint polar ring. This bridge stretches for almost 100,000 light years, equivalent to the diameter of our Milky Way. The face-on galaxy appears to be going through a period of star formation, as would be expected in such an interaction, with many bright star clusters.

A faint edge-on third galaxy is seen just above and left of the top Arp 87 galaxy. Several other faint background galaxies are also visible throughout the image.

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.
