NGC 5860

This Astrobin Debut Object is a pair of colliding galaxies located 250 million light years away in the constellation of Bootes at a declination of +43 degrees. The pair span 1 arc-minutes in our apparent view. This corresponds to a width of 80,000 light years.

This object is fascinating to me, with its tidal star streams, blue and yellow separated cores, and common inner disk. Usually by the time a merger has progressed to the point that the tails are this diffuse, the cores have merged. In this case, the 2 cores (blue and yellow) still appear distinct. I have not seen another merger object quite like this one.

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.
