The dust and gas clouds, MBM 54 (part of the Integrated Flux Nebula) in our galaxy, lies maybe 1,000 light-years from us; the galaxy is about 60,000,000 light-years distant. Several other small, distant galaxies hide behind the cloud as well. Much of the molecular cloud MBM 54 receives faint illumination from the general background of stars. Still, a close look at the image shows almost pitch-black and starless regions of nearly unilluminated nebula. Although quite apparently, cloud densities vary significantly in this region, and some gas streamers have been found, there is no evidence for star formation. The streamers have been attributed to shock waves generated, perhaps, when denser regions with the cloud collide (Sakamoto, 1999). Many such streamers appear in this image.

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.
