James Webb and Keck-telescopes cooperation uncovered the clouds in Titan's atmosphere.



"Images of Saturn’s moon Titan, captured by the James Webb Space Telescope’s NIRCam instrument November 4, 2022. Left: Image using F212N, a 2.12-micron filter sensitive to Titan’s lower atmosphere. The bright spots are prominent clouds in the northern hemisphere. Right: Color composite image using a combination of NIRCam filters: Blue=F140M (1.40 microns), Green=F150W (1.50 microns), Red=F200W (1.99 microns), Brightness=F210M (2.09 microns). "

Titan-moon is quite similar to Ganymede. The largest moon of Jupiter. The question is why does Ganymede not have a dense atmosphere? 


Titan is the biggest moon of Saturn. It's the only moon in our solar system that has a dense atmosphere. And that thing makes this moon remarkable. There are clouds in the Titan atmosphere. And that thing means there is also some kind of particles. They are forming clouds in the atmosphere of that very cold. The average temperature on Titan is 93,7K  (−179.5 °C). So those clouds can form around the small ice bites. 

There is 2.7±0.1% of methane (CH4) in the Titan atmosphere. And that thing can form methane ice in that atmosphere. 

There is no oxygen on Titan. And that denies the oxygenizing reactions. So that thing can make Titan a very interesting place. In that chemical environment, things like carbon-based molecules can stay almost forever. 

James Webb and other telescopes can uncover new details from that very extraordinary world with hydrocarbon oceans. Titan is a very dry moon, and there is no known water. But the dense atmosphere that is mainly nitrogen makes that moon very interesting. 

Because it should be like a freezer where is lots of material from the young solar system. The atmosphere protects those organic compounds from the UV radiation that comes from the Sun. So maybe the origin of life is stored in that icy moon. The nitrogen atmosphere of Titan is unique. The pressure of the atmosphere is 1,42 atm atmosphere. 

But the mass of that moon is lower than Ganymede, the largest satellite in the solar system. The surface gravity of Titan is 1.352 m/s2 (0.138 g) (0.835 Moon's) and the surface gravity of Ganymede is 1.428 m/s2 (0.146 g). The question is why Ganymede has no dense atmosphere. Maybe the distance from the Sun explains why Titan has its nitrogen atmosphere and Ganymede has not that thing. 




"Evolution of clouds on Titan over 30 hours between November 4 and November 6, 2022, as seen by Webb NIRCam (left) and Keck NIRC-2 (right). Titan’s trailing hemisphere seen here is rotating from left (dawn) to right (evening) as seen from Earth and the Sun. Cloud A appears to be rotating into view while Cloud B appears to be either dissipating or moving behind Titan’s limb (around toward the hemisphere facing away from us)."

"Clouds are not long-lasting on Titan or Earth, so those seen on November 4 may not be the same as those seen on November 6. The NIRCam image used the following filters: Blue=F140M (1.40 microns), Green=F150W (1.50 microns), Red=F200W (1.99 microns), Brightness=F210M (2.09 microns). The Keck NIRC-2 image used: Red=He1b (2.06 microns), Green=Kp (2.12 microns), Blue=H2 1-0 (2.13 microns). Credit: NASA, ESA, CSA, W. M. Keck Observatory. A. Pagan (STScI).

Insect swarms can electrify air the same way as thunderstorms.



The reason. Why electricity in flashes of lightning is so powerful is that the thundercloud loads electricity into them until electricity travels to the ground. There is the possibility that insect swarms would get the same electric load as thunderclouds. If insects are flying at high altitudes and radio impulses are hitting them. That can raise the electric load on their body to a high level. 

When small insects flap their wings. They can form static electricity in their tiny hair. The insect's hair acts like all other hair. And when it moves, it forms static electricity. Even if the voltage of one insect is not very high,  billions of insects can form quite a high-power electric phenomenon. 

There is also possible that static electricity forms the ion channel in the air which conducts lightning to a certain point. Even a weak ion channel makes the point where electricity can travel easier than elsewhere. And that thing can cause problems with communication systems. 

Insects are searching warm places. And the electric field can disturb high-speed data communication. Also, there is the possibility that insects can aim lightning at that communication equipment. 

Also, insects themselves can load with electricity. When insect swarm flies in the electromagnetic field like radio waves that radiowaves load electricity onto their bodies. When radio waves are loading electricity onto the insect's bodies they face a similar effect as starlings when they are sitting on electric wires. 

They will not get an electric shock because they are not touching the ground. When starlings touch the ground. Electricity travels away from it. 

The electric load continues to grow until it would hit to ground. But the insect itself will not feel anything. But when that insect sits on something. Electricity travels out from it. And if that thing is some kind of electric device that electric shock can disturb or even destroy the system.

The strange inventions and cloud photos


The strange inventions and cloud photos

As you see above this text, here are a couple of photographs after a long period. Here they are again. Below this text is a series of cloud photos, what I have not sent to this homepages recently. I know that this might be some kind of joke, but sometimes I have thought that maybe this kind of photos have been used as the stimulant for people who want to make the new kind of aircraft and other advanced tools for military and civil industry.

The ideas of the fly by benefiting the natural electricity is a very absurd idea, because the electricity, what the lightning would give is unstable, and the energy level is very high. But there have been the ideas for that thing before the generators have been invented, and the high voltage electricity was unable to create. In that time some inventors created the idea that the power of the electricity would conduct to the Leyden bottles and that would be a suitable way for storing the high voltage electricity for the electric arc tests. And maybe some inventors created an idea to replace normal fire in hot air balloon by using electric arc.

When we are thinking about the Blue Book material and the photographs of the aircraft, we must realize, that the scientists and designers would get the form from their product from nature. The ideas of the flying saucer-shaped aircraft would be getting from the silly thought, what I sometimes have thought, and that is that the high voltage electricity was able to get before generators straight from the flashes of lightning.  In the ideas of the inventors was to create the aviation vehicle, what would use electric arc for flying, and the electricity was getting from the lightning.

The idea for that vehicle was given by Nicola Tesla or some other genius like Viktor Schauberger. The idea was to create the saucer-shaped craft, what will fly by using electric arc by giving the force to rise that thing from the ground, and the high-voltage electricity for that device would get from the lightning, which power would store in the capacitor.

This kind of way to load batteries is unstable but the power of the lightning is huge, and that force of nature can use in the flying craft, what would fly by using electric arc. The thing is that inside the balloon would be installed the electrodes, what would make an electric arc and the energy for that system can be stored from the lightning by using the capacitors. When the person wants to fly with the balloon, that inventor must just connect the electric wires to the capacitor, where the electricity of the lightning has been stored, and then the electric arc would rise it over the ground.

The reason why we are not using that way to produce electricity is that the flashes of lightning would have extremely high voltage electricity and the use of that power is unstable because there are no flashes of lightning all the time. There have been ideas to conduct the electricity from the clouds to the capacitors peacefully by using the mast, which would rise to the could, and conduct the electricity to the capacitor. And this kind of things was tested or used before the electric generators have been invented.
