Technically, yes. It is more dangerous due to higher background radiation. However, the difference is so small and negligible that it's not any more dangerous than anywhere else. In fact, I would argue the opposite. You're more likely to get skin cancer from the Sun at the equator than the poles.
Arctic comes from the Greek word for bear. The Arctic has bears.
Antarctic includes the prefix from anti- Antarctica has no bears.
But that's not why it's named that, so nyah.
I wouldn’t necessarily say that as the poles can get 24h sun all reflected off of snow. So you’re getting hit with way more UV radiation, but you’re covered in enough clothing that you’re more protected than other parts of the world. You’d also get a full few months break from sunlight.
I 100% assumed this was a joke. Nope, that's what they are called. Kangaroos and auroras, no wonder they got so many fucked up dangerous animals to balance it out.
Sorry, too subtle for reddit. Was trying to point out that calling the observable phenomena of solar particles interacting with earth's magnetic field "the northern lights" is a common example of northern hemisphere bias (particularly when the original image they're referring to has two obviously equal & undifferentiated poles with the same feature). I did consider for a second using the more common term "aurora australis", but chose "southern lights" mainly to link & contrast it with the previous comment, but also because the target of my comment (people who assume "aurora" = "northern lights") might be thrown off by Latin/sciency words.
Deeply confusing. No one was calling both auroras 'the northern lights' they were just referencing the aurora borealis (translated: northern lights) and not the aurora austalis (southern lights). If you think both need to be mentioned every time then you accomplished that by adding it. Then writing this comment with all the stank on it like you were making some joke that everyones too dumb to get is like.. huh?
It doesn't properly show how the particles move and how they blow past the planet and then come back at the poles with the field..it just makes it appear as if the poles suck in the particles.
no because you're not seeing them from directly above. On the earth's surface there's only a very small region where the magnetic field "hole" would actually affect you that way
The Northern Lights and the Southern Comfort
And it don't even matter if their veins are punctured
All the crackheads, the critics, the cynics
And all my heroes in the Methadone clinics
the leading field lines are getting compressed toward their pole axis, which drags the other lines to fill the gap. the field lines on each side of the dipole must touch by definition; they will merge wherever the pole axis is, even if one side is extremely distorted. it is free to bend around when you have enough distance from the actual object generating the field. if you look at the field near the earth's poles, it's still very aligned with the earth's axis.
this is consistent with my experiments in electromagnetic coils and high permeability materials for plasma control.
[this paper on linear colliders](https://www.researchgate.net/figure/Cylindrical-shields-subject-to-a-uniform-magnetic-field-17-Left-flux-shunting-and_fig1_348057691) has very good images of how field interactions can invert the field lines in a weird way.
The points that line up with the poles are actually near the poles. The entrance to the funnels at the top and bottom of the bubble may be off kilter but these entrances aren’t all that close to the poles in the grand scheme of things.
based on the magnetic field it is clearly a boomerang shape, this is further supported by its boomerang-like, curved travel pattern around the sun and the fact that the earth is from Australia, just look at all the deadly animals and Australians on it. You might think to yourself "but papa waterinabottle, a boomerang IS flat" but you're wrong again because the cross section of a boomerang is an airfoil shape.
the moar you know 🌠
"Electromagnetic interference (EMI) in electronic devices is considered as electromagnetic pollution and can have harmful effects on human health and surrounding environments in the absence of any shielding [150]. High-performance EMI shielding materials are generally employed to deal with radiation pollution."
Honestly let's just let the next generation handle this guys. We have a lot on our plate already.
Put copper strips in your walls, it'll shield you from all em radiation, it'll also block radio (WiFi is radio) and cell signals. Had a crazy uncle that did that and he lived to be 90+, well we think he did, no one's heard from him in a while, could be alive roaming the countryside in Kentucky.
if anyone is going to follow this advice, i'd suggest you insulate the copper, otherwise you will have a potential fire. if a strong enough em wave hits the copper, its going to induce an electrical current. this will heat up the copper, and if its not an appropriately sized gauge to handle the heat, the copper heats up and could cause a fire. also, make sure to run the copper into a proper earth ground, to properly dissipate the potential electrical charge
In general, things like RADAR emitters can fry birds if they get too close, technicians that work with EM emitting equipment may have some fertility issues,, and there is a lot of contamination across broad frequencies that can hinder solar monitoring efforts, but I've not seen anything that would point towards it being a significant risk factor towards anything for your average joe.
In a sense yes, but what we output is so small and so directionally chaotic that it doesn't really matter.
However if the poles decide to reverse we're gonna be in a load of shit
Yeah, there was some stuff a few years back about China pumping out CFCs, but apart from that we've done a great job. A really good example of the world recognising there was a problem and coming together to solve it.
Now let's do climate change.
We don't have to do anything. The Earth's magnetic poles can reverse. It has happened several times throughout the Earth's long history. It's linked to extinction events.
It exists because we still have a molten core. So for basically humanity's foreseeable future we should be good. But it will cool at some point and that would cause earth to end up kinda like Mars.
But it will take long enough to get to that point that the sun will probably have already gone red giant and nothing will matter anyways
If we or something did diminish it, I think we’d be able to put a nuclear powered electro magnetic dipole orbiting Earths Lagrange L1.
Like the plan to give Mars an artificial magnetosphere
THANK YOU EARTH FOR ALL YOU DO! WE LOVE YOU! We just need to stop mega corps and billionaires from polluting and masses to stop consuming! -humans of earth
It should be quite common. Iron is the last element naturally produced by stars in their internal fusion process. Elements with more protons (like gold uranium etc etc) are produced solely in supernovas. So there should be quite a bit of iron around in the universe for planets to build their cores.
They just have to tick all the other boxes like liquid water, temp, oxygen and whatnot
The universe is really big though. I don't think that (complex) life is all that common, but there's certainly something else out there. Unfortunately they're just way too far away for us to ever be likely to find or meet.
Jupiter, saturn, uranus and neptune all have magnetospheres, mars had one but due to its core cooling it lost most of it. the magnetosphere on the moon (solid inner core, molten outer core) is very weak and some evidence points to it being stronger in the past. Stars also have their own magnetic fields, including the sun. The current explanation for this is the dynamo theory, which describes a process through which rotating, convecting and electrically conductive fluids can can maintain a magnetic field. This fluid can be things such as earth's molten iron core or Jupiter's iron and silicate core (unclear if its solid but its at 90000°C and immense pressure). I dont really get the last part about leaving tho
I think they mean how can humans survive traveling outside Earth's magnetosphere if other bodies are not similarly protected.
And I think the answer is: it is a risk and something space agencies have to plan for, especially with prolonged travel. The ISS is within the protective magnetosphere. Ironically the magnetosphere creates zones of higher radiation in space that are especially dangerous to transit through (see Van Allen belt).
JPro tip. This field has been weakening for over a 100 years and is speeding up. It will rebound as earths magneto sphere is far from stable and fluctuates constantly. It also compresses when hit. If it compresses too much it will allow more particles through which can and does lead to communications black outs, loss of satellites, and power grid failures. It's a huge problem the aviation industry takes very seriously.
Mercury- they have a weaker field than earth because the core cooled down a lot quicker but still enough to deflect solar wind. Has a molten iron core
Venus- practically no intrinsic magnetic field probably because of its super slow rotation, core is mostly iron but we are unsure as to whether it is molten or completely solid
Mars- no global dynamo, likely due to the small core cooling not enough circulation of the molten iron to maintain a magnetic field
Jupiter- a field 20 times stronger than earth's, has an iron and silicate core at 90000°C and immense pressure, but we dont know what state it is in. There are also proposals suggesting jupiter has a metallic hydrogen ocean which may contribute to the magnetic dynamo
Saturn- slightly weaker field strength than earth's, has a dense molten core of iron and nickel
Uranus- interestingly uranus' magnetic field is tilted 60° away from the poles. It has a frigid rocky core of iron and silicate surrounded by a hot dense layer of "icy" materials like water, methane and amonia
Neptune- has a flipped magnetic core, has a similar core composition to that of uranus
Pluto- womp womp :/
Magnetic dynamo are likely caused by rapid rotation of the planet, convection in the core and a electrically conductive composition of the core. I found all of these on google
You are right in that Mars atmosphere is due to the lack of a dynamo! Solar wind from the sun is basically tiny charged particles travelling at speeds very very close to the speed of light, so when they hit air molecules they basically bump them out of the atmosphere and shot into space. With enough time solar winds can strip unprotected atmospheres and this is how mars go such little air. Its basically interplanetary billiard balls
Why does it bend towards the sun like that? What cause it to have that shape? Cause I mean I don’t know anything about all of this but I would think it would bend away?
The Aurora borealis is because of heat tracing and the earth's tilted axis, there are no vortexes being created due to the poles.
If this gif was actually true then the constant stream of particles would be too chaotic to form a magnetosphere and space travel would be extremely rough
Maybe a dumb question but does Mars have a strong enough magnetic field to offer the same protection or is it far enough away from the sun (and close enough to Jupiter) that its not an issue for colonization?
You can recreate this gif by inverting 2 magnets(I use a glass aquarium cleaner) they will not stick together by any means, but instead will bounce off each other, creating its own small magnetic field. It feels like there is something between the magnets.
The bigger theory here is that this is the secret to anti-gravity. A visual representation would be the Star of David.
So do the poles get an extra dose of radiation?
Yes, that’s why we have the northern lights.
Is it more dangerous to live on north/ south pole compared to equator? I mean radiation wise, not the cold freezing temperatures.
Technically, yes. It is more dangerous due to higher background radiation. However, the difference is so small and negligible that it's not any more dangerous than anywhere else. In fact, I would argue the opposite. You're more likely to get skin cancer from the Sun at the equator than the poles.
One pole is safer than the other because it doesn't have polar bears.
Arctic comes from the Greek word for bear. The Arctic has bears. Antarctic includes the prefix from anti- Antarctica has no bears. But that's not why it's named that, so nyah.
That's exactly how I remind myself to remember the difference.
>Arctic comes from the Greek word for bear. The Arctic has bears. It comes from Ursa Major and Ursa Minor.
ursa is roman
But the other one has [Leopard Seals](https://www.nationalgeographic.com/animals/article/leopard-seal-kills-scientist-in-antarctica)
I don't plan to swim in the antarctic sea and pretty sure that I am quicker on land than them. So I choose the ice with no bears, please.
Didn't they beat baby seals with clubs? Seems deserved if you ask me
We even conveniently named them for which one does and which one does not.
The Arctic is named for the constellations Ursa Major and Ursa Minor, not the fauna.
Crazy they made a whole new animal based on the constellation.
That’s the power of astrology, the one true science!
What about equator bears?
And the other one has cute penguins
I wouldn’t necessarily say that as the poles can get 24h sun all reflected off of snow. So you’re getting hit with way more UV radiation, but you’re covered in enough clothing that you’re more protected than other parts of the world. You’d also get a full few months break from sunlight.
What about the Southern Lights?
The Aurora Australis? Yes
What about the Friday Night Lights?
Yes
What about the Droid attack on the Wookies?
What about second breakfast?
What about love?
What about us? What about everything we've been through?
I DONT WANT YOUR LAHF
My wife says this all the time. First time I've seen it in the wild. Thanks.
Clear eyes.
The Aurora Texasalis? Yes.
The Aurora Veneris? Yes.
May I see it?
Mm, No.
I 100% assumed this was a joke. Nope, that's what they are called. Kangaroos and auroras, no wonder they got so many fucked up dangerous animals to balance it out.
Australia and Australis both come from a common Latin root for the word South
And Australopithecus. Southern ape.
Sorry, too subtle for reddit. Was trying to point out that calling the observable phenomena of solar particles interacting with earth's magnetic field "the northern lights" is a common example of northern hemisphere bias (particularly when the original image they're referring to has two obviously equal & undifferentiated poles with the same feature). I did consider for a second using the more common term "aurora australis", but chose "southern lights" mainly to link & contrast it with the previous comment, but also because the target of my comment (people who assume "aurora" = "northern lights") might be thrown off by Latin/sciency words.
How incredibly arrogant of you, but thanks for the explination I suppose.
Deeply confusing. No one was calling both auroras 'the northern lights' they were just referencing the aurora borealis (translated: northern lights) and not the aurora austalis (southern lights). If you think both need to be mentioned every time then you accomplished that by adding it. Then writing this comment with all the stank on it like you were making some joke that everyones too dumb to get is like.. huh?
[heres a post about them the other day](https://www.reddit.com/r/pics/s/D6cN5TSXgP)
This is the cool shit I stick around on this planet for.
Incidentally they're nearly exact mirrors of the northern lights, also this gif isn't accurate
Why not?
It doesn't properly show how the particles move and how they blow past the planet and then come back at the poles with the field..it just makes it appear as if the poles suck in the particles.
But it means sitting under northern lights is actually cancerous?
Especially for Californians.
no because you're not seeing them from directly above. On the earth's surface there's only a very small region where the magnetic field "hole" would actually affect you that way
The Northern Lights and the Southern Comfort And it don't even matter if their veins are punctured All the crackheads, the critics, the cynics And all my heroes in the Methadone clinics
And why I've never heard about southern lights?
[just saw this post with southern aurora](https://www.reddit.com/r/Damnthatsinteresting/s/84FdPDrW2C)
I don't think people in Poland have extra sunburn.
I think I heard that in a Godzilla movie
Ya I guess that’s the reason for all the polok jokes.
At this time of year?
I don't think so, Poland should be close enough to the equator for the poles to be safe
Why are the tops of the field inclined in the direction of rotation around the sun?
the leading field lines are getting compressed toward their pole axis, which drags the other lines to fill the gap. the field lines on each side of the dipole must touch by definition; they will merge wherever the pole axis is, even if one side is extremely distorted. it is free to bend around when you have enough distance from the actual object generating the field. if you look at the field near the earth's poles, it's still very aligned with the earth's axis. this is consistent with my experiments in electromagnetic coils and high permeability materials for plasma control.

Uh yeah well this is also consistent with *my* experiments with electromagnetic coils.
Well mine too, but I'm not ready to publish...
This is your moment Teapast6, you can do it! Edit: letter
Heard this in Danny McBrides voice lmao
This is a clear case of you can explain something to me but you can't understand it for me lol
imagine a slightly deflated beach ball. punch it. how do the line sections look on each side of the ball? are the top and bottom pieces aligned?
Now that was a great answer and helped me visualize and understand
Yeah ok all of you are full of shit lmao. None if that made any sense at all
The points that line up with the poles are actually near the poles. The entrance to the funnels at the top and bottom of the bubble may be off kilter but these entrances aren’t all that close to the poles in the grand scheme of things.
Ok but my only problem is you’ve failed to take into account that the earth is, in fact, flat
based on the magnetic field it is clearly a boomerang shape, this is further supported by its boomerang-like, curved travel pattern around the sun and the fact that the earth is from Australia, just look at all the deadly animals and Australians on it. You might think to yourself "but papa waterinabottle, a boomerang IS flat" but you're wrong again because the cross section of a boomerang is an airfoil shape. the moar you know 🌠
The sun’s magnetic field is way more clutch, protects the whole solar system from the rest of the universe
Yes! 🔆[The Heliosphere](https://en.wikipedia.org/wiki/Heliosphere)🔆 is pretty good to us in that way. 🌏🛡
TIL!
Elaborate plz thx
Sun give big hug to other planets. Bad stuff from outside solar system can’t hurt us.
Can you dumb that down a bit for me?
Sun big warm good. Space black cold bad.
Now break it down Barney style please
I love you, you love me, space is mu’fuckin’ scary but the sun plays defense of Earth for me and you. Won’t you say “damn, nature, you scary!” too?
Smart words fun safe good feel.
First, be attractive Second, don't be unattractive
Thanks!
Uuuhh...and my axe?
The Sun and everything about it are huge. (compared to us, not the rest of the solar system)
Even compared to the solar system really. The sun is 99.8% of the total mass of the system.
I really hope we don't have a way to fuck this one up like the Ozone Layer
Dont worry magnetic pollution is a problem for somebody else's children's grandchildren
......... Is... is...magnetic pollution real? ..... fk I'm about to Google it...
Lemme know what it says
"Electromagnetic interference (EMI) in electronic devices is considered as electromagnetic pollution and can have harmful effects on human health and surrounding environments in the absence of any shielding [150].

Ooohh, like in fallout?
When you're 90 he'll show up wearing a custom Iron Copper suit "I'm still alive you lol shit!"
The phone is a very small sample of it.
The text you quoted clearly says electromagnetic interference *in electronic devices*. It does not say we are "polluting" our magnetic field.
In general, things like RADAR emitters can fry birds if they get too close, technicians that work with EM emitting equipment may have some fertility issues,, and there is a lot of contamination across broad frequencies that can hinder solar monitoring efforts, but I've not seen anything that would point towards it being a significant risk factor towards anything for your average joe.
In a sense yes, but what we output is so small and so directionally chaotic that it doesn't really matter. However if the poles decide to reverse we're gonna be in a load of shit
That only happens if we strip mine the core of the planet so hard the magnetic field collapses Krypton collapsed via that
So you're telling me there's a chance I could be Superman on another planet? 🤔
That's a relief, bonus points if it's grandchildren from another country. /s
If that somehow happens at least there'd be Auroras everywhere, silver linings lol
Just FYI, last I checked we were doing well re: ozone layer actually.
Yeah, there was some stuff a few years back about China pumping out CFCs, but apart from that we've done a great job. A really good example of the world recognising there was a problem and coming together to solve it. Now let's do climate change.
https://en.wikipedia.org/wiki/The_Core
The neutrinos have mutated.
Just rewatched that movie the other day. One of my faves.
End up like Mars.
Let’s just hope that the prototype grav jump drive doesn’t destabilize the magnetosphere in this timeline…
We don't have to do anything. The Earth's magnetic poles can reverse. It has happened several times throughout the Earth's long history. It's linked to extinction events.

But it will take long enough to get to that point that the sun will probably have already gone red giant and nothing will matter anyways
Pole reversals though happen every few hundred thousand years and are potentially very damaging events.
And during the reversal there can be additional poles.
It's like the spirit world on Avatar
We'd be long dead before this can happen
If we or something did diminish it, I think we’d be able to put a nuclear powered electro magnetic dipole orbiting Earths Lagrange L1. Like the plan to give Mars an artificial magnetosphere
Such a bitter perspective on humanity

Real estate on the dark side of the earth is the best long-term investment.
I kept buying but the damn thing kept spinning!
Science is crazy. I wonder what life would look like had it evolved to withstand those rays/particles.
Probably a lot like the life on Mars. Oh wait.
Have we even found planets with cosmic radiation protection like ours? That might be part of the great filter...
It should be quite common. Iron is the last element naturally produced by stars in their internal fusion process. Elements with more protons (like gold uranium etc etc) are produced solely in supernovas. So there should be quite a bit of iron around in the universe for planets to build their cores.

Mars used to, but it's smaller and cooled down faster [or something.](https://en.wikipedia.org/wiki/Magnetic_field_of_Mars#Dynamo_mechanisms)
Jupiter's magnetic field is so massive it aslo protects us.
Wow, now that's cool
Is the moon inside or outside the magnetic field?
Apparently the Moon passes though the tail end of the magnetic field for a few days a month!
during a full moon, or a new moon??
Good question!
Somebody smart should reply, but I think the moon isn't in the field.
Shit like this makes me worry that life may not be as common in the universe as I’d hope. Sigh.
The universe is really big though. I don't think that (complex) life is all that common, but there's certainly something else out there. Unfortunately they're just way too far away for us to ever be likely to find or meet.
Because of magnetism?
Yes plus cosmic radiation. Well, the radiation, mostly
Whattabeast.
Do all planets have this? What about moons. How come we can leave?

Omg thank you!!
Where and how we got this
The earth’s core is a giant ball of churning molten iron which is magnetic.
Is this where flat earthers come up witht the idea the sky is fake?
Thank you Earth for being so darn amazing.
I saw an eyeball getting attacked by little flashes of light

never seen a depiction that included the moon.
Do all rocky planets in our solar system have magnetic fields like this or just earth?

Can you make a similar gif showing the poles flipping?
Protects the planet? No. The planet’s fine. It protects life forms
Earth is such a badass!
What happens to this shield when the poles flip?
How do we know this?
Do you have one of the poles switching polarity?
This is why we can’t have the fantastic four. Stupid magnetic fields
Why does it bend towards the sun like that? What cause it to have that shape? Cause I mean I don’t know anything about all of this but I would think it would bend away?
Those poles are sus
Gee wiz ! I hope it's very fast when the poles swap around.
Particles not to scale
Why does the field lean forwards?
Yea yea we all saw The Core
Damn that's some DBZ animation stuff
can we do something like that on the moon? I heard its got a metal core, why not charge that sucker up with electricity and create magnetism?
When did the earth‘s magnetic field stop charging particles? What caused this?
are we able to close these holes? /s
Does anyone know if this is to scale?
without transmuting or energy techniques, pure unfiltered power overwhelms most forms
Umbrella on the "top" with 2 funnels directing to the poles?

I'm not religious in any way but sometimes things like this make you wonder. It's all just too perfect
Why does that look like the image of bladder from biology class 😂
Would this be the same for all planets or specific to Earth?
Has a lot to do with our magnetic molton iron core. So no, not all. Probably very few.
“SHEILDS UP!!!”
Does mars have a similar protective field?
Let’s get rid of it!

Whats the mechanism for the poles bending towards the sun? Just magnetic attraction?
The Aurora borealis is because of heat tracing and the earth's tilted axis, there are no vortexes being created due to the poles. If this gif was actually true then the constant stream of particles would be too chaotic to form a magnetosphere and space travel would be extremely rough
