The Northern Lights Essay -- essays research papers fc
The Northern lights ar poetry, they argon natures light show, and they arequantum leaps in the oxygen atom. They are elementary particle physics,superstition, mythology and fairy tales. The northerly lights suck up filled pot with wonder and inspired artists they have frightened people tothink that the end is at hand. More exact explanations of the phenomenoncould not be given until modern particle physics were developed, andknowledge about detail in the earths magneto sphere has been based onmeasurements from satellites.When the northern lights are seen all over Troms, it happens in a set manikin,although this pattern varies considerably. The outburst run shorts with aphosphorocent effulgence over the horizon in northwest. The glow peter outs out andcomes back, and then an arch is lit. It drifts up over in the sky. And nakedarches are lit and follow the first one. Sm wholly waves and curls move onthe arches.Then within a few minutes a striking change is seen in the sky. A hail besetof particles hit the upper atmosphere in what is called an aurora sub-storm.Rays of light shoot down from space, forming draperies, which spread, allover the sky. And they in truth remind us of draperies or curtains, which areflickering in the wind. And you peck see a violet and a red trimming at thelower and upper ends. Or the colors are mixed all together, woven into eachother. The curtains are disappearing and forming all over over again by new raysof light shooting down from space. Above our notch we cans see rays going outin all directions forming what is called an aurora corona. aft(prenominal) 10 to 20minutes the storm is over and the activity decreases. The bands are spreadout, disintegrating in a diffuse light all over the sky. We can not seeindividual pockets of light, but the total nub is bright enough to enableus to make out expatiate of the countryside around us. If we look verycare uprighty, we can see the remains of the northern lights display as fa int,pulsating flames. Clouds of light which is turned on and off on a regular basis every5 - 10 seconds as though by an galvanising light-switch. The natures owngigantic light show is over.What causes the northern lights? To answer this, we start with the sun whoseenergy production is far from even and fluctuates on an 11-year cycle. supreme production coincides with high sunspot activity when processes onthe suns surface commit particles ... ...ll over the sky.7) Bands of northern lights one higher up the other, raising towards the zenithindicates that the sub storm is starting.8) Rays of light shoot down from space tells about higher activity.9) Draperies are formed with waves at the lower end.10) Curls and waves wave along the draperies.11) The draperies look as if they are flickering in the wind. Maximumactivities close.12) The interaction between the go charged particles and the earthscharismatic field creates a charging magnetic field. The particles stream downalong the m agnetic field lines.13) Rays and draperies can die out in one place of the sky, and form atanother.14) During the upper limit of a sub storm, the whole sky can be full of light.15) An all-sky (fish eye) picture showing that the draperies are stretchedfrom east to west, through zenith.16) When the activity reaches Zenith, by an optical illusion, it seems likethe rays stretch out in all directions above our heads. This form of thenorthern lights is called aurora corona.Works Citedhttp//www.uit.no/npt/nordlyset/nordlysbilder.en.htmlhttp//www.uit.no/npt/nordlyset/Way North Magazine, issue by Troms Museum.
