Magnetosphere Definition and 17 Threads

I'm not sure how to set up the pressure balance at the magnetosphere? Maybe some energy equation relating ##\frac{1}{2} \dot{M} v^2 \sim## magnetic energy density?

Summary: Can such magnetosphere exist on Earth? The moon has mini magnetospheres produced from its crust shown below. Can Earth have similar magnetic properties in its crust like the surface on the Moon to create a mini-magnetosphere? Are ther places on Earth where a mini magnetosphere exist...

According to recent research news, swedish PhD scholars have said that solar wind induces currents in the ionosphere of mars. This causes an induced magnetoshere which in turn protects the atmosphere from the same wind. This is quite difficult to believe. It is well known that Mars does not...

I would say that this looks more like Aurora Australis. What is the reason for these changing colors? https://www.space.com/22594-aurora-bottle-northern-lights-show.html

Do the formation of auroras always occur in circles/ovals/ellipses?? What causes the shape of their formation?

(I am of two minds about posting this here or in the main satrophytsics forum, but I think it's probably better to go here.) So, I have a tide-locked planet at approximately 104AU out around a clone of R Coronae Borealis, with has a carefully designed , bright shiny silvery moon (small and...

I just had this idea/vision of panels being placed in front of the sun, then the energy collected is beamed to a receiver/transmitter orbiting Earth. I suppose with an energy 'Magnitude' of the sun, a little bit of 'loss' due to Earth's atmosphere is not a big deal but... I wondered what if you...

how does this phenomenon occur.?this a case of magnetosphere..I don't understand how this happens.

Hi, Earlier this month, I was searching for trends/graphs on solar activity. I found some good sites which I cannot post due to me being a forum noob ;-) Now, I am looking for the equivalent except this time, in relation to earth's magnetosphere levels (strength) Does this exist ? Thanks, Danny

Would this noticeably increase the radiation level on Earth? Or would the atmosphere easily stop the excess solar-wind particles which are now not being deflected away?

what is the size of a galaxies magnetosphere? Is it's size or have any relation to the size of he black hole/blackholes? or to the mass at the center of the galaxy? Is there any kind of intergalactic wind (Like the solar wind) that interacts with a galaxies magnetosphere like our...

Is it possible to tap into the Magnetosphere to generate power? I mean the core of the Earth is in fact a giant generator, so why can't (or aren't) we exploiting this potential?

If one surveys stars, and their planetary systems, of 4.5 - 5 Byrs old; and then detects terrestrial exoplanet of say 1.5 Earth masses, then one probably still has a magnetosphere - if we are typical (Copernian Principle). And if in habitat zone, then also look for oxygen signature in...

For those who don't know what H.A.A.R.P. is, here is a description of some of it's capabilities. "United States Patent 4,686,605 Eastlund August 11, 1987 Method and apparatus for altering a region in the Earth's atmosphere, ionosphere, and/or magnetosphere ... "Weather modification is...

Hi, I don't have a solid background in astrophysics. I need some help. Jupiter's magnetosphere is elongated by the Sun. It almost reaches the orbit of Saturn. What would happen if, by increased solar output, the magnetospheres touched? Recently we had a conjunction of Jupiter and Saturn...

How do solar wind particles get trapped in a planet's magnetosphere? The particles travel along the Sun's magnetic field lines, right? And then they switch to traveling along the planet's field lines? How? When they get trapped, are they still supersonic? Is it correct to say that...
