ESO 550-25

This Astrobin Debut Object is a pair of interacting spiral galaxies located almost 0.5 billion light years away in the constellation of Eridanus at a southern declination of -19 degrees. Each galaxy has a diameter of about 40,000 light years. One is more edge-on and one more face-on.

Both galaxies have some yellow and blue color, which is surprising for the distance. As usual, the Hubble mouseover here contains much more detail.

The 2 galaxies appear to be in the M2S merger stage (connected with a short bridge). I like the star stream curling tail which extends up and to the right of the pair.

Very few galaxies that I have imaged are designated by only the ESO (European Southern Observatory) catalogue. Most galaxies principally have NGC, UGC or PGC designations, but not this object.

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.
