NGC 4490 and NGC 4485, The Cocoon Galaxy

NGC 4490 and NGC 4485 known as the Cocoon Galaxy is a pair of interacting galaxies that lie approximately 29million light years away from earth. It was initially discovered byt William Herschel in 1788.

These galaxies are interesting in that it can easily be seen how they are interacting with each other. These galaxies have already made their closest approach and are now moving away from each other. In their wake is a 25000 light year long stream of gas and star forming regions (nebulae).

NGC 4490 (the larger of the 2 galaxies) is estimated at 53000 light years in diameter. NGC 4485 is about 11000 light years to compare to our galaxy these are relatively small as the Milky Way is estimated at 100,000 light years and our neighbor the Andromeda Galaxy is 220000.

I took this image from my parents yard in Bortle 3 Skies of North Central Arkansas. This was processed in pixinsight and photoshop. Hope you enjoy.

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.
