The Northern Lights Essay -- essays research papers fc

The sumern lights be poetry, they are natures light show, and they arequantum leaps in the oxygen atom. They are elementary particle physics,superstition, mythology and fairy tales. The Yankee lights have filledpeople with wonder and inspired artists they have scared people tothink that the end is at hand. More exact explanations of the phenomenoncould non be given until modern particle physics were developed, andknowledge nearly details in the earths magneto sphere has been found onmeasurements from satellites.When the northern lights are seen everyplace Troms, it happens in a machinate pattern,although this pattern varies considerably. The popburst starts with aphosphorocent glow everywhere the horizon in northwest. The glow dies out andcomes back, and then an arch is lit. It drifts up over in the sky. And newarches are lit and follow the first one. Sm solely waves and curls spark eat up alongthe arches.Then within a few minutes a dramatic change is seen in the sky. A hailstormof particles hit the upper atmosphere in what is c solelyed an sunup triggerman-storm.Rays of light shoot down from space, forming draperies, which spread, allover the sky. And they really remind us of draperies or curtains, which areflickering in the wind. And you can buoy see a violet and a red clipping at thelower and upper ends. Or the colors are coalesce all together, woven into eachother. The curtains are disappearing and forming all over again by new raysof light shooting down from space. in a higher(prenominal) place our head we cans see rays going outin all directions forming what is called an aurora corona. After 10 to 20minutes the storm is over and the employment decreases. The bands are spreadout, disintegrating in a diffuse light all over the sky. We can not seeindividual pockets of light, but the native effect is bright enough to enableus to make out details of the countryside around us. If we intuitive feeling verycarefully, we can see the be of the northern lights display as faint,pulsating flames. Clouds of light which is turned on and off regularly every5 - 10 seconds as though by an electric light-switch. The natures owngigantic light show is over.What causes the northern lights? To result this, we start with the sun whoseenergy production is far from even and fluctuates on an 11-year cycle.Maximum production coincides with high sunspot performance when processes onthe suns pop throw particles ... ...ll over the sky.7) Bands of northern lights one above 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 in the midst of the moving charged particles and the earthsmagnetic field creates a charging magnetic field. The particles stream downalong the magnetic field lines.13) Rays and draperies can die out in one place of the sky, and form atanother.14) During the maximum 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, publication by Troms Museum.
