The shark nebula (LDN1235)

There is no sea big enough to accommodate this harmless predator, made up of interstellar gas and dust.
The grains of this dust have about the consistency of cigarette smoke and were generated in the relatively cool atmospheres of giant stars. After being expelled with the gas and gravitationally recondensed, the massive stars carve intricate structures in these dust clouds using their intense radiation and powerful winds as chisels. The heat they generate evaporates the cloudy molecular cloud and disperses the surrounding hydrogen while ionizing it. It is during this phase of disintegration that we humans can see familiar figures in the shapes of these great cosmic clouds, as we do with the clouds in our atmosphere. Comprising smaller dark nebulae like Lynds 1235 and Van den Bergh 149 & 150, the Shark Nebula spans about 15 light-years and lies about 650 light-years away in the constellation King of Ethiopia, Cepheus.

When the light (emitted or reflected) of this nebula "left" to hit my photographic sensor, the provost of Paris, Aubriot, lays the first stone of the "Bastille" in France.

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.
