What Causes the Aurora Borealis? Fairbanks, Alaska. During the early 19th century, some of the best scientific minds of the period believed that the aurora was caused by the reflection of sunlight from tiny ice crystals suspended high in the atmosphere.

Northern Lights - Aurora Borealis in Iceland, Land of the Sagas The Northern Lights occur high above the surface of the earth where the atmosphere has become extremely thin, at an altitude of 100-250 km. They are created by electrically charged particles that make the thin air shine, not unlike a fluorescent light.

- The aurora borealis, or northern lights, illuminates the night sky above Lake Superior in Michigan's Keweenaw Peninsula on Nov. 3, 2015. The red beach is the result of light from the photographer's head lamp. Photograph taken at North Canal Township Park, where the Keweenaw Waterway meets Lake Superior.

Aurora Borealis AURORAS OCCUR along ring-shaped regions around the north and south geomagnetic poles. Fairbanks, Alaska, is a good place for Aurora watching because it is under this region in the north, where people see Aurora Borealis, or northern lights; the southern Aurora is Aurora Australis. LIKE A NEON SIGN, auroral light is produced by a high-vacuum electrical discharge.

- The Aurora Borealis is made when storms on the the sun form solar winds, or large streams of charged particles streaming toward the earth.These streams could have upward of te … n million megawatts of electrical power. That is enough power to light up Los Angeles.

- The typical aurora is caused by collisions between fast-moving. electrons from space with the oxygen and nitrogen in Earth’s. upper atmosphere. The electrons—which come from the Earth’s. magnetosphere, the region of space controlled by Earth’s mag-. netic eld —transfer their energy to the oxygen and nitrogen.

How does the aurora borealis (the Northern Lights) work? The auroras, both surrounding the north magnetic pole (aurora borealis) and south magnetic pole (aurora australis) occur when highly charged electrons from the solar wind interact with elements in the earth's atmosphere. Solar winds stream away from the sun at speeds of about 1 million miles per hour.As the electrons enter the earth's upper atmosphere, they will encounter atoms of oxygen and nitrogen at altitudes from 20 to 200 miles above the earth's surface. The color of the aurora depends on which atom is struck, and the altitude of the meeting. 1  Green-oxygen, up to 150 miles in altitude.

It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet.

Aurora Borealis Some Alaskans have Aurora Alerts; when a display begins, the first person to spot them begins a phone tree to get the word out. The pulsating Aurora is one form of Northern Light common during the post-midnight hours.

Alaska Northern Lights Tours No matter what you call them—the northern lights, or aurora borealis—these green bands of light in the sky are seriously cool to see. They're actually solar particles blown into the earth's magnetic field more than 60 miles above the earth's surface.

What is the Aurora Borealis? Aurora Borealis which is also known as Northern Lights because it is seen mainly and clearly in the Northern Hemisphere, is a band of light of red and green, seen in the sky… at night or by sun set near the North Pole.

- Unforgettable experience. The Northern Lights tour in Iceland takes you to see a spectacular natural phenomenon which happens during the winter months. The Northern Lights, also known as Aurora Borealis, are caused by the interaction of particles from the sun with the upper atmosphere near the North Pole.

The Northern Lights â Icelands Aurora Borealis The northern lights or aurora borealis occur mainly as a result of solar wind particles and ions which flow outwards from the sun towards the earth.

- 1 The Northern Lights are caused by the interaction of the solar wind-a stream of charged particles escaping the Sun-and our planet's magnetic field and atmosphere. When these field lines snap back into position, charged particles from the solar wind are again pushed into the Earth's atmosphere, causing aurora. 2  The more magnetic field lines that disconnect and snap back, the further south the Northern Lights can be seen.

What Causes the Aurora Borealis Colors? The aurora is the name given to the bands of colored lights seen in the sky at the higher latitudes. The aurora borealis or Northern Lights are seen mainly near the Arctic Circle. The aurora australis or Southern Lights are seen in the southern hemisphere.The light you see comes from photons released by oxygen and nitrogen in the upper atmosphere. Energetic particles from the solar wind strike the layer of the atmosphere called the ionosphere, ionizing the atoms and molecules.owever, the colors of the aurora are different on different worlds because the atmosphere is different. The only requirement for a planet or moon to have an aurora is that it have an atmosphere that is bombarded by energetic particles.

What layer of the atmosphere is the Aurora Borealis? Because Aurora Borealis a.k.a. the Northern Lights occurs near the north magnetic pole (in northern Canada and so it can only be seen from far north places like Canada. Philip … pines is near the equator so i doubt it.

What causes the aurora borealis? Bottom line: When charged particles from the sun strike atoms in Earth’s atmosphere, they cause electrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights.

- the aurora depends on where in the magnetosphere the electrons came from and on what caused them to precipitate into the atmosphere. Dramatically different auroral shapes can be seen in a single night. Where can I see the aurora? Auroras usually occur in ring-shaped areas centered around the magnetic poles of Earth. The complete rings, called the auroral ovals, can only be seen from space. False color picture of the auroral oval in ultraviolet light. The brighter the color, the more intense the aurora. The crescent of color on the left is from sunlight scattered over the upper atmosphere. The best places to see the aurora are in Alaska, Canada, and Scandinavia, during the late evening hours. Resident of the northernmost United States – near the Canadian border – typically see auroras several times a year. On rare occasions – perhaps once per decade – auroras are visible as far south as Florida or Japan.

Aurora Borealis: What Causes the Northern Lights & Where to See Them The colors most often associated with the aurora borealis are pink, green, yellow, blue, violet, and occasionally orange and white. Typically, when the particles collide with oxygen, yellow and green are produced. Interactions with nitrogen produce red, violet, and occasionally blue colors.

- Rings around the Poles. The electrons that create auroras start in the outer layers of the field, where it is compressed by the solar wind. They accelerate along the field lines, converging toward the magnetic poles from all directions. This results in an oval ring around each magnetic pole where auroras occur.The north pole aurora is called the aurora borealis and the aurora at the south pole is called the aurora australis.ings around the Poles.
