Thank you very much for this collection jupiterbeings. The sketches are very interesting.
The "Etoiles courants" look a little like contrails. I don't know the physics but it makes me wonder if contrails could be caused by "comens etc."?
During the last few months I saw a lot of very orange / reddish sunsets and sunrises. They were similar to the orange/red skies in the comet sketches...
When I saw these pictures I was reminded of an water colour of Albrecht Dürer - Traumgesicht (dream vision). When I searched for I found that he also made a couple of pictures with unusual things falling from the sky (e.g. comets, stones) or symbols I connect with these.
Traumgesicht (dream vision) - This picture is depicting a dream with a huge lot of water falling down (sheets of rain?).

Got wende alle ding zu{m} besten.
Albrecht Dürer"
Text below (English Translation):
`In 1525, during the night between Wednesday and Thursday after Whitsuntide, I had this vision in my sleep, and saw how many great waters fell from heaven. The first struck the ground about four miles away from me with such a terrible force, enormous noise and splashing that it drowned the entire countryside. I was so greatly shocked at this that I awoke before the cloudburst. And the ensuing downpour was huge. Some of the waters fell some distance away and some close by. And they came from such a height that they seemed to fall at an equally slow pace. But the very first water that hit the ground so suddenly had fallen at such velocity, and was accompanied by wind and roaring so frightening, that when I awoke my whole body trembled and I could not recover for a long time. When I arose in the morning, I painted the above as I had seen it. May the Lord turn all things to the best.

Albrecht Dürer 21 May 1471 – 6 April 1528) was a German painter, engraver, printmaker, mathematician, and theorist from Nuremberg. He lived during the dark ages when there was black death in Europe. For me he seem to depict what he has seen sometime.
