The Moons Atomosphere

Ok so as far as I understand the moons gravity is holding the gas that it has but it is also possible that in part static is attracting and repelling some of this gas. Do this sound right?

I think the solar wind/sunlight is constantly reacting with the Moon's surface forming gases and then leaking them to outer space. I've forgotten where the article is now.

Roughly. But remember from the link you posted earlier, the moon is not really considered to have an atmosphere because it isn’t held in place by gravity (long term) and needs to be constantly replenished (mainly by outgassing from the surface).

OK. So between the moon and earth there is also some of these gases as well? solar winds and among other stuff?

Formation like chemical reaction between gasses?

Does this sound good?

Yes, that's the sort of thing I read.

It didn't say anything about nitrogen. Why wouldn't nitrogen share over?

Yes. There is some gas (and dust) between the planets in the solar system: https://en.wikipedia.org/wiki/Heliosphere

There is some, but less, between the stars in the galaxy: https://en.wikipedia.org/wiki/Interstellar_medium

And even less between galaxies: https://en.wikipedia.org/wiki/Warm–hot_intergalactic_medium

"Still, we only have a partial list of what makes up the lunar atmosphere. Many other species are expected."

Presumably there isn't enough to detect easily.

Awesome! I didn't even know to search for that stuff

"(mainly by our gassing from the surface)" I think your spelling might be causing some confusion here. Did you mean out instead of our?

Oops. Autocorrect on the phone! (Yes: "outgassing")

Oh. So pretty much all planets and moons do this? arrow up

So totally off subject but I have to ask. One of the links is saying that our systems bowing out from the north of the sun and in from the south. Could this mean that our system is moving in a southern direction from the suns point of view?

Yes. But for different reasons. On the moon it is mainly the effect of solar radiation and wind on the surface ,material. On Earth it is volcanic (or, more generally, plate tectonic activity) and radioactive decay of elements in the crust. And the scale is different. Almost the entire "atmosphere" of the moon is generated by outgassing, while the amount of gas added to the Earth's atmosphere is a tiny amount compared to the total mass of the atmosphere.

I don't think so. We are moving, roughly, sideways: https://www.space.com/3801-solar-system-sails-sideways-milky.html

I think that asymmetry is unexplained. Maybe turbulence?

So this turbulent fluid that this article is describing, When the friction is happening in between the particles that are involved in this turbulence could static electricity be generated to create this magnet field effect? Another question I have is in cars the spark has to increase in voltage to jump the resistance of the combustion pressures. As the pressure increases so does the resistance as far as I understand. Would space be less resistant due to the lower density or is that up to whats occupying the spaces near it as to how conductive it is?

The gases and the solar wind are largely plasma (atoms with electrons stripped of) so static electricity is not really a possibility.

 Also, static electricity does not create magnetism. You need moving charges (such as the plasma and solar wind).

The breakdown (spark) voltage is roughly proportional to density. It also varies depending on the gas. Some examples here: https://en.wikipedia.org/wiki/Dielectric_gas

ok I see. So the particles from the article appear to be from a collapsed magnetic field. Is this article saying that the movements between the charged particles (turbulence) are whats creating the magnetism of the galactic magnetic field as of right now?

Sort of a self perpetuating cloud of charged particles maybe.

Not something I know the details of. But you have a magnetic field created by the galaxy, the magnetic field of the Sun, the magnetic field created by the solar wind, the magnetic fields created by the interaction of the heliosphere and the interstellar medium ... So I doubt there are any simple answers.

"Bowing out" made me think of the asymmetry of the earth magnetic field and wonder if that has an impact of properties of the moon discussed in this topic. I tried to find references to see if the moon passes through earths magnetic field and found science-at-nasa/2008/17apr_magnetotail

Didn't have much time to research but I found this*, worth adding in this context:

Earth is largely protected by its magnetic field, or magnetosphere, but new University of Washington research shows that some parts of the moon also are protected by the magnetosphere for seven days during the 28-day orbit around Earth.

We found that there were areas of the moon that would be completely protected by the magnetosphere and other areas that are not protected at all,” said Erika Harnett, a UW assistant research professor of Earth and space sciences.

Using computers to model properties of the magnetosphere, Harnett found that while solar storms can increase the danger from ionosphere particles hitting the moon they also trigger conditions in the magnetosphere that deflect many hazardous solar particles.

ref: Earth’s magnetic field could help protect astronauts working on the moon

So when doing experiments on the moon regarding some phenomena in this thread I suggest this adds to the complexity.

Yes indeed, and that's part of the fun

 

*) have not checked for other sources backing up the claims in the news article

Interesting point. I haven't looked into this much yet, but I assume that this protection would be more of a "shadowing" effect rather than being directly caused by the Earth's magnetic field.

But this is interesting (and relevant to the thread):

Also, NASA scientists have suggested that Earth's magnetotail might cause "dust storms" on the Moon by creating a potential difference between the day side and the night side.^[14]

That's pretty good stuff.

[Theredbarron]

So do you think its possible to make my own little statically charged cloud using the right mix of stuff? I would put this in a chamber of course.

Get yourself a van de graaff generator and a girl with long hair and you can create a cloud of hair around her head...
