SH2-87 - SH2-88

Sh2-87 and Sh2-88 constitute, together with the nearby SH2-86, the edges of a kind of "bubble" centered on the core of Vulpecula OB1, one OB association located in the initial stretch of the Orion Arm at about 6500- 7500 light years from the solar system; Within this bubble are columnar structures of gas, similar in appearance to the famous Pillars of Creation visible within the Eagle Nebula (M 16). The formation of these structures, in general, is most likely due to the strong disintegrating and erosive action of radiation and the stellar wind. Massive stars located near fairly dense nebulous areas, gradually consuming denser nebulous cocoons by forming long hairs behind them. The "tops" of these clouds, which are in direct contact with the radiation of nearby stars, are compressed until they collapse at various points, thus generating protostars.

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.
