Dark Tower of Scorpius

This object, the Dark Tower of Scorpius, is located 5000 light years away in the southern constellation of Scorpius. The object is 40 light years long. It is a tough object for many of us to image because of its declination of -41 deg.

This object is described as a cometary globule - an isolated cloud of gas and dust within the Milky Way with a dense, dark head and a long faint tail, with some clumps slowly collapsing to form stars within the dark nebula. The cloud is shaped by intense ultraviolet radiation from the hot stars in the large star cluster NGC 6231, which is off image to the upper left. That same radiation is causing the reddish glow of hydrogen gas. This image helps to accentuate the hydrogen glow by supplementing the normal RGB data with Ha. Small bluish reflection nebulae can be seen in some of the stars embedded in the dust.

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.
