The Cocoon Nebula IC5146, from a Bortle 6 patio

While observing IC 5146, the presence of the dark nebula Barnard 168 (B168) significantly enhances the experience. This dark nebula creates a distinct obsidian path encircling the cluster. This pathway extends towards the west, resembling a trail trailing behind the Cocoon.

IC 5146 stands as a celestial cradle where the birth of stars continues unabated. Utilizing data from the Spitzer Space Telescope and the Chandra X-ray Observatory, scientists have collectively pinpointed the existence of numerous fledgling stellar entities. These juvenile stars make their appearance within both the emission nebula, an area where gases have been ionized by youthful massive stars, and the infrared-shrouded molecular cloud that gives rise to the distinct "tail" formation.

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.
