Barnard 92, the Black Hole

Barnard 92 is an interstellar dust cloud, contrasting nicely against the bright background of the Small Sagittarius Star Cloud, M24. This dark spot has been nicknamed the Black Hole, long before this term was used to describe strongly gravitating objects - B92 is certainly not a Black Hole in the relativistic sense, but a dark nebula. It is one of the first dark nebulae known, discovered in 1913 by E.E. Barnard (Barnard 1913).

Barnard 93 is the smaller dark nebula, with a head and tail, at the top of the image. Both nebulae are estimated to be 10,000 light years from the Earth.

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.
