Sh2 86

What you see is an emission nebula and a star-forming region located about 6,000 light-years from us. At the top right of the image is the open star cluster NGC 6823, a collection of newly formed stars that originate in the emission nebula. Most of the stars in this cluster are between 2 and 5 million years old. Within Sh2 86 (on a blue background) are a series of pillars, similar to those found in the Pillars of Creation in the Eagle Nebula. These pillars form when radiation from newly formed stars pushes gas and dust out of the nebula. Also shown in this image to the right of the main pillar are numerous Bok globules. These globules will eventually collapse to form new proto stars. This image explains very well "how" new stars are built. For the acquisition of the image I have used the 3 usual narrow band filters accumulating about 43 h of exposure.

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.
