Simeis 188

When stars form, pandemonium reigns. A particularly colorful case is the star-forming region Simeis 188 — the cloud that houses the nebular complex. It is approximately 4,000 light-years from Earth in the constellation of Sagittarius located just below the famous Lagoon Nebula(M 8), The regions that bask in vivid red signal the existence of emission nebulae(IC 4685, IC 1274, and IC 1275) which are common fixtures throughout the universe, being that they are tied to star formation. Then we venture into the accompanying blue hues—reflection nebulae(NGC 6559). They form when light from embedded stars encounters dense concentrations of dust, scattering more efficiently toward the blue end of the electromagnetic spectrum. Pretty much every other type of nebula is represented here as well, including dark nebulae and absorption nebulae. Simeis 188 also has a much more famous neighbor located just one degree north of it, the Lagoon Nebula.

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.
