Barnard 72 - Snake Nebula

It's time for another Namibian shot. This time, it's the Barnard 72 Nebula (B 72), also known as the Snake Nebula, in the constellation Ophiuchus.

This dark nebula was discovered by Edward Barnard at the beginning of the 20th century. Observing objects of this type, we subconsciously get the impression that we are looking at an area without stars - a dark void. In reality, we are dealing with dense dust obscuring a multitude of stars.

Considered relatively nearby, located at a distance of 650 light-years, B72 is a compact nebula stretching 6 arcminutes. It is relatively narrow, with a thickness ranging from 2 to 3 arcminutes. The densest part of the dust cloud forms an S-shaped structure winding for 5 light-years, which is why it was initially called the "S" Nebula and later the Snake Nebula.

Noteworthy is also a series of smaller nebulae classified both by Barnard and belonging to the LDN (Lynds Dark Nebula) catalog, with the darkest and densest being B68.

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.
