Arp 244 (2019) (Gary Imm)

Arp 244 (2019)

This object is a pair of colliding galaxies (Caldwell 60 and 61) located 60 million light years away in the constellation of Corvus. I find this object to be one of the most visually fascinating of all of the deep sky objects. The galaxies have been deformed so severely by their gravitational interaction that it is hard to even recognize the original shape of each galaxy. The cores of the two galaxies can be seen in the two brightest areas located next to each other at the same vertical height in the image.

The starburst phase typically associated with interacting galaxies is clearly seen in the many pinkish star formation areas of each galaxy. Beautiful dense star streams are evidence that this interaction has been occurring for a long time. Along with everything else, the dust lanes have been warped into a knotted wonderful mess. The transition of these two galaxies into a single galaxy should be fun and interesting to watch for the next million years.

The two long tidal tails have a combined length of almost 400,000 light years. The long tails in this image are a great example of how tidal interactions cause star streams to flow out of the outer galaxy disk regions when two galaxies approach each other.

I like so many things about this object - the fascinating graceful overall shape, the 3-D look, the detailed star streams and the beautiful star background. My favorite part of this image is the wonderful color diversity, which is unusual for a galaxy image. I see so many colors - the usual blues and pinks, but also varying shades of yellow, orange, brown, gray and bright white.

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.
