NGC 6820 in SHO

NGC 6820 is an emission nebula located in the constellation Vulpecula. It is about 6,000 light-years away from Earth. The nebula is about 40 arcminutes across, or about 1/3 of a degree. It is a beautiful object, with a complex structure of pillars, filaments, and bubbles. The nebula is illuminated by a young open cluster of stars called NGC 6823. The cluster is about 2 million years old, and contains several hot, massive stars. These stars emit powerful ultraviolet radiation, which ionizes the gas in the nebula, causing it to glow.The pillars and filaments in the nebula are formed by the interaction of the stellar winds from the stars in NGC 6823 with the surrounding gas and dust. The stellar winds are strong enough to blow away the gas and dust, but they are not strong enough to completely destroy it. Instead, they carve out channels through the material, leaving behind the pillars and filaments.

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.
