 so you may be wondering why i'm choosing to tap on a musical album cover um talking about space it's because this is meant for exploring the mind is the other realm of the unknown and then set that down for appropriate peace so the magnetospheric multiscale or m m mission studies it's the mission that studies the mystery of how magnetic fields around earth connect and disconnect explosively releasing energy via a process known as magnetic read the mission observes reconnection directly in earth's protective magnetic space environment magnetosphere by studying the um reconnection in this local natural laboratory mass helps us understand reconnection elsewhere as well such as in the atmosphere of the sun in other stars and in the vicinity of black holes and neutron stars and at the boundary between our solar systems heliosphere interstellar space you're being taught about the solar system and the planet i think science can come across as so dead and lifeless and um the more you understand that it's not just a bunch of balls of rock with some gas only orbiting mundanely around this you know spotlight i think maybe i should have named this channel let's find all instead of let's find out because that's what informs that's what guides me when i'm looking for topics consider talking about our sun is protecting us yet potentially killing us at the same time nuclear for your own statistic it's it's a it's a it's millions of nuclear thermonuclear explosions being relatively contained by the mass of the particles being fused together there's so many of them i mean the universe the solar system rather is gather maybe we can sense of all hidden layer to our the solar system the magnetic pumped out from our sun it's being it's a bit of panic fields between across 90 m of space so that's what science fiction is often obsessed with the idea of portals but it actually turns out that they do exist and we can see here these little um this is a not to scale depiction of our sun and the interaction between these two magnetic fields and there's these little points and this is some research that is funded by nasa and our government it's really really optimistic to know that our government still is funding these seemingly useless probes into the inner workings the the nature of nature of our universe and it has very productive useful results but it's very cool that we are part of a civilization that is putting forth a fair amount of money not as much as maybe we should but still nonetheless it is where we're really really causing our own little part of the universe and as cool as it is to look way billions of years away in the space of light years away i think it's fascinating and awe inspiring that the plasma physicist jack scutter university of iowa they're places where the magnetic field of earth connects to the magnetic field of the sun the nasa's thymus stir probes suggest that these magnetic probes dozens of times every day i'll wait till i get to the little this is a really cool relative to the rest of the universe of course in the field lines and how they this is of course two dimensions but extrapolated to three dimensions you see here from south pole to north pole the lines go out create a loop or in three dimensions they create a bubble of sorts here they don't go as far out because this is the sun facing side and of course the earth is always rotating so it's again very dynamic but the sun in solar winds mostly get brushed the earth is just constantly brushing brushing these uh actually air of course that's metaphor and there's this thing right here called the bow shock and that is the pretty much the threshold at which beyond it outside of our away from earth field no more significant magnetic field for uh from the earth and you're very very very much exposed to pretty much the full brunt of the uh of the solar wind at that point okay but these um these magnetic portals that that we're talking about here field is uh is almost like these ropes it's like these these large cylinders wrapping around and they wrap into each other but still remain distinct ropes the process the process of magnetic reconnection mingling lines of magnetic force from the sun and earth criss cross and they join to meet the openings they join to create the openings called x-point it's crazy so yeah let me just show you because i have the transcript i'm reading from but um the visual is the best way that i understood we have the solar winds buffeting there you go this visual these um elastic bands you know it's like the earth has these magnetic elastic bands that get buffeted and as this polar spacecraft spent years in earth's magnetosphere decided to see how an x-point looked to the polar using polar data polar data they found five simple combinations of magnetic field so this is how they're gonna detect them but i want to find out more about what about the nature of them here's the mission overview well let's let's get into the science just a little bit understanding of it the sun doesn't bombard solar wind doesn't rocks and flames it's protons and electrons it's these uh cosmic particles and of course it's propagating outward in concentric circles from the sun it's not just a unidirectional laser beam hitting the earth so all the planets in their magnetic fields are very much dynamically the sun the source is the sun of course in these reactions super heat the gas surrounding the star create plasma when a volcano explodes tons of ash is sent into the sky and the same thing happens on the sun or full blast of energy in december in a marked one of the observed in 25 years hot sunspots were um actually pretty active areas of the sun because they're funneling magnetic field lines out of them i don't know we'll figure that out so the sun is blasting out its plasma into the solar system the speed of the particles depends on how active the sun actually is particles could move at over a hundred thousand miles in a second opposite sides of the same coin planetary magnetic field well it's like not only us is this a ridiculously gravitationally bound super massive a create all right guys i mean that's pretty much i'll end it with the mission overview for the magnetospheric multi-scale mission nasa launched the magnetospheric multi-scale mission going to be magnetic reconnection sites on the sun side of earth the reconnection can link the sun's magnetic fields um it's magnetic field lines to earth material and energy from the sun to funnel into earth's magnetic inside of earth reconnection is believed to help trigger also known as the northern and southern lights oh it's uh it's kind of like a hyper-conductive freeway for the solar particles of the cosmic particle the plasma that's ejected from the sun reconnection occurs when magnetic field lines cross and release a gigantic yeah i guess that's something in the history of college we have no we really don't have the faintest idea of its fundamental nature you know like i could say the big bang i could say god but we don't know ultimately where when what it gives that to me is so yeah just so meaningful
