Northern Lights The Northern lights, you could see them in the North pole. They look beautiful right, well have you ever wondered what causes the beautiful colors in the sky? Have you ever questioned yourself about there history or their sound and shape? How are Northern lights formed? Northern lights form when charged particles are released from then sun into Earth's atmosphere that hit the gas-like particles in the North pole that cause the lights you see and know as auroras. There's two kinds of auroras, "aurora borealis" (northernlightscentre.ca) located in the North that means "dawn of the North." (northernlightscentre.ca) Also, "Aurora Australis" (northernlightscentre.ca) located in the South that means "dawn of the South." (northernlightscentre.ca) …show more content…
Have you ever wondered what cause the different colors?
Well, it all depends on the different gases in the Earth's atmosphere and the height the gas is in. The red around the arc, cloud, or streak shapes are nitrogen molecules they're low in the atmosphere at about "100km/60 miles" (www.athropolis.com) yet the red in the shape is oxygen in a high altitude "above 300km/185 miles." (www.athropolis.com) The yellow/green color is oxygen in low altitude "between 100-300km/60-185 miles." (www.athropolis.com) The blue and purple are hard to see in nights sky but they are created by hydrogen and helium in high altitude Some of them move, brighten, or flicker all of a sudden. You could see them more "during the most intense phase of the 11 year sunspot cycle." (The World Book Encyclopedia, 895-896) Is it possible to hear the Northern lights? Many say they have heard crackling, swishing, and hissing sounds but scientist haven't been able to collect any real evidence that the Northern lights make sounds. It possibly might have to do with the thin air because it's to thin to produce a sound wave. "Sound is a longitudinal wave-as the wave passes through the air moves backwards and forwards in the pipe, this oscillatory movement is in the same direction the wave is traveling." (galileo.phys.virgina.edu) Since the air is to thin it can't do
that. How much do you know about the Northern light's history? Did you know the oldest known aurora seen was written about in "2600 B.C." (www.nasa.gov) in China. It read "Fu-Pao, the mother of the Yellow Empire Shaun-Yuan, saw strong lighting moving around the star Su which belongs to the constellation of Bei-Dou, and the light illuminated the whole area." (www.nasa.gov) In "1619 A.D." Galileo Galilei invented aurora borealis, Aurora after the Roman goddess of morning. In "1790" (www.nasa.gov) Henry Cavendish used "triangulation" to calculate the lights are about "60 miles" above Earth's surface. In "1902-1903" (www.nasa,gov) Kristian Birkeland said "aurora lights are caused by currents flowing through the gas of the upper atmosphere," (www.nasa.gov) this is known as the "terrella experiment." (www.nasa.gov) Therefor, the gas-like particles released from the sun and into Earth's atmosphere causing the colorful Northern lights. The colored lights are caused by the different gases at different altitudes. Yet, they have no sound but appear as arcs, clouds, and streaks.
... in the sky, described as a bright color change to a “sad universal tint of dingy purple” (216).
...nd violet wavelengths are the shortest, and violet is the least visible to the human eye. These wavelengths are scattered throughout the day and caused by a redirection of the light-waves direction due to gas molecules in the atmosphere (Mc Knight, p. 84). When the sun is setting towards the end of the day there are few blue wavelengths left and we see orange and red which are dominant and the longest wavelengths of visible light to the human eye. At the bottom of the photo (closest to the setting sun) red and orange are the dominant visible colors with the occasional blue and almost violet. If our eyes could not see orange and red our sunsets would be a dark blue or black.
James Wright was a poet that dealt with many hardships in his life, but he found a way to turn those negative moments into beautiful works of poetry. As a child, he lived in poverty with his family and later on suffered with depression and alcoholism. Growing up in Ohio, Wright learned how to work hard which is reflected in his poetic achievements. Wright turned his struggles into poems and for him to be able to achieve success through his pain is what makes his work American. Frank McShane wrote “The Search for Light” in Peter Stit and Frank Graziano’s James Wright: A Profile, and in the book McShane includes: “James Wright knew how restricted most American lives were” (131). For Wright to be able to live the “restricted” life McShane is discussing,
(Vol 48, 900). Another requirement of necessary conditions for lighting to occur is that greater heights of the -10 isotherms that are greater than a kilometer above ground level are “also conductive to lake effect lightning because this condition allows more graupel to form in the warmer cloud.” (Vol 48 900). Having a higher equilibrium level greater than 3.6km will allow greater cloud depth to develop convection. Minimal wind shear and more signalized snow bands instead of multiple bands will enhance the
Larry Watson, in “Montana 1948”, uses the motif of light and silence in many ways to develop, clarify and reinforce ideas about truth and injustice, and portray the nature of some characters. He illustrates the injustice in Bentrock through the motif of light and then demonstrates to the reader the occurrence of something wrong through the motif of silence. The motif of light also sometimes assists the motif of silence to emphasize the significance of the event.
Pullman used the concept dust in Northern Lights. Dust is a convention for human physically inspired by God's judgement. It is not just the ending and the beginning of human physical existence and the origins of universe. Pullman was influenced by John Milton the paradise lost and his concept dust. Pullman used the word to connect everything with everything and the parallel worlds. The church considers dust as the original sin. The oblation board wants to cut and sever the daemons of the children to prevent the dust from setting on the child and to prevent daemons to settle when children become adult. The church thinks that dust may threaten its absolute power. The individuals that go through cutting their daemons operation will be subject
Hope has the incredible ability to make or break someone. People are always told to make large goals in school and employment, and try to reach those ambitions no matter how far they are. Hope is the motivation behind accomplishing dreams, but it also has the ability to break people who have hoped for something so desperately, yet never came to fruition. Only determination and personal situations can persuade hope to fly or fall. A Northern Light by Jennifer Donnelly highlights this ambiguous hope we depend on through the use of symbolism, characterization, and inner conflict.
Northern Lights deals with the forces of love, betrayal, religion and science; all of these themes spur from one source, power. Each character in the novel experiences these topics, because each character is powerful. Northern Lights shows us that all individuals must either choose to use or be overcome these forces.
Numerous places and religions have suggested a reasoning around the Northern Lights to give some sort of explanation. However, it could be that people just needed another entity that guided their beliefs in some way. As time went on scientists clarified what the Northern Lights really are, “The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere.” (Northern Lights Center). This interaction between the sun and Earth cause a display of many different colors. They include shades of red, yellow, green, blue, and violet. However, pale green and pink are the most common colors seen. The Northern Lights and sunspot activity has been around since about the 1880’s, but people did not fully know of the reason for these lights until the 1950’s. The different gases in our atmosphere are the reason for the colors produce in the sky. Oxygen molecules cause the yellowish-green color that is seen a lot, while nitrogen produces a blue or purplish-red color. “The temperature above the surface of the sun is millions of degrees Celsius. At this temperature, collisions between gas molecules are frequent and explosive. Free electrons and protons are thrown from the sun's atmosphere by the
Dark wave is a unique and exceptional music genre that began to appear in the late 1970s in the German music circle. This genre of music rose on the popularity of post-punk and new wave. Dark wave is usually dark and has introspective lyrics with an undertone of sorrow. Dark wave bands and their fans have grown in number and known as wavers and the scene took off in the 1980s. This type of music started to gain impedance in Europe and slowly started to get bigger over that decade. This brooding genre of music remains as pertinent as ever.
...ve different colors, colors tell about a star’s temperature, composition, age, size, and distance. Red stars are usually older; coolers stars have used up much of their hydrogen fuel. Blue stars are much younger and hotter. Most of Orion’s stars are blue except for the very red star, Betelgeuse. Orion is most easily seen from the months of November through February. The latitudes at which Orion can be best seen are 85 and -75 degrees. Its right ascension is 5 hours, and its declination is 5 degrees.
The moon has multiple effects on Earth and Earth’s surface. The moon affects Earth by its gravitational pull and its revolution around the Earth. This gravitational force can affect many different aspects of Earth, and also has some myths about it. Some of these myths include: a full moon affects humans by causing tides in us; the moon doesn’t have gravity; and there is a permanent dark side of the moon.
There are various references in Roman, Russian and English records. There are have records in 1192 of this great Aurora observed by many throughout the world. It’s kind of interesting that this global event, the Aurora, was recorded and a lot of people experienced it but they couldn’t really talk about it like we do today across countries and cultures. People saw that it was recorded in many places in the early 1700’s. There were multiple accounts of intense Aurora from China, New England, and Europe. In 1859, there was the Carrington solar and in the days following there was the brightest of Aurora events that have been accurately recorded and written down. It was observed all the way to South America. This intensity hasn’t been seen since and unlikely to be seen before that. In the 1500’s people believed that the Aurora was kind of like a birthday cake in the sky with candles dancing around according to some drawings found. People didn’t know that it was electrical currents flowing from the Sun.
