Arp 286

This object is a trio of galaxies located 80 million light years away in the constellation of Virgo at a declination of +4 degrees. The data shows that all 3 galaxies in this trio are at a similar distance.

The largest galaxy is NGC 5566, with an apparent size of 6 arc-minutes and a diameter of 150,000 light years. This magnitude 10.5 barred spiral galaxy has broad sweeping arms and subtle but clearly visible dark dust lanes. The dust lane on the lower right side is more detailed than that of the upper left side, likely indicating that the lower right side is the near side of the galaxy and the upper left side is obscured by the galaxy halo.

NGC 5566 has a yellowish tint, likely due to its age, in contrast to the bluish tint of its neighbor on the upper left, NGC 5569. The third galaxy, NGC 5560, has both colors - yellow in the core and blue in the arms.

Both NGC 5566 and NGC 5560 appear distorted due to the gravitational pull between the galaxies. The arms of both galaxies appear slightly warped. It is not clear to me whether the smallest galaxy is interacting with the other two, but literature sources say that all three galaxies are interacting.

I am surprised that I don't see any pinkish star formation areas anywhere amongst the trio. Such areas are typically found when galaxies are interacting.

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.
