What you're looking at is NGC 2081 and surroundings, an emission nebula in the Dorado constellation, around 160000 light years from earth.

As is common for these types of regions, we see a lot of hydrogen gas and interstellar dust. But what is this dust exactly and where does it come from?

While the exact properties of said dust clouds are a bit difficult to describe in a few words; the short version is that they're made up from various heavier elements (carbon, silicon, iron,...). As the stars within our universe age (and generations of them come and go); the nuclear furnace in their cores will start fusing heavier and heavier elements to keep the star stable (until it can't and the star dies). Some of these elements remain present within the star until the end of its life; quite a bit of them get ejected out into space by stellar winds (in essence the nuclear pressure pushing outwards partially overwhelming the stars own gravity). In heavily populated areas of space (meaning lots of active stars in relative close proximity); these ejected elements will clump together and form these dense clouds.⁣

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.
