Lagoon (M8) and Trifid (M20) Nebulae

Lagoon Nebula ( NGC 6523 or M8 ), is an ionized-hydrogen region located about 5,200 light years away in the constellation of Sagittarius. Interstellar dust within the nebula absorbs some of this light and appears almost to divide the nebula, thus producing a lagoon like shape.

Trifid Nebula ( NGC 6514 or M20 ), like the Lagoon nebula is an active star-forming region located 9,000 light years away also in the constellation Sagittarius. It is called the Trifid because the nebula is overlain by three bands of obscuring interstellar dust, giving it a trisected appearance. It contains very hot blue stars type O from which intense radiation is sent outwards affecting the surrounding 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.
