Strange holes in the Florida sky



Souce


The NASA satellite called Terra has photographed the strange voids known as drop holes or perforated clouds, these in particular are over the Gulf of Mexico very close to the Florida coast.


The photo was taken on January 30 and NASA's Earth Observatory made them public on February 26. Circular holes are not as rare as these you are seeing, they began to be seen in the 1940s and also began to appear. Ideas emerged that, if they were UFOs, if they were cosmic energies, there were theories of all kinds, however, the reality is much more normal.


These holes are created by airplanes that fly between the clouds, specifically by cloud banks called altocumulus clouds. These clouds can reach up to 5500 m and are very cold, they can reach up to -15 degrees Celsius and despite being so cold The water vapor and water particles that form these clouds do not freeze and fall.


This is because at that high altitude there are fewer small particles such as dust or pollen that are necessary for nucleation to form and end up initially forming ice crystals in the air, but when the air moves around the wings of The planes that pass through those clouds can cool that water vapor even more, those particles, and when those particles cool down a little more, they end up freezing completely and end up falling, creating these holes.

And these holes have caused a certain collective sensation, but I already said that they are not strange at all, they have a quite normal explanation, it is due to the passage of airplanes in certain types of clouds, while the type of spirals above are already becoming famous, they have been seen In previous months and other years spent in Australia, in New Zealand these in particular are taken from Iceland and Norway and the fault in this case, like the others, lies with SpaceX, it is not because Spacex wants to make spirals, this is a side effect of the needs of how SpaceX rockets work.


And these phenomena also have a somewhat boring explanation, it is that in the travel missions of SpaceX rockets like the falcon 9, there are a lot of satellites, equipment, from different clients and with different destinations, to be able to to make the satellites go and head to their different destinations, the rocket must rotate the second stage to deploy in order to deploy, which is why the second stage when it rotates when it is spinning still does so when it is burning and therefore the gases it expels in that twist are what form this spiral that we see.
