- WHAT IS THE AURORA BOREALIS? The Aurora is an incredible light show caused by collisions between electrically charged particles released from the sun that enter the earth’s atmosphere and collide with gases such as oxygen and nitrogen. The lights are seen around the magnetic poles of the northern and southern hemispheres.

Aurora ―PDA, Dialogue. The Aurora is a spacecraft sent to the Ariadne Arm by the Alterra Corporation in order to build a phasegate. However, its secondary mission, unknown to most crew, was to search for and, if possible, rescue the survivors of the Degasi crew.

Aurora Australis When auroras occur, it lasts for fifteen to forty minutes and with a two to three hours break. The most common colors of aurora lights are green and pink. This is brought about by the presence of the gases in the atmosphere. More oxygen, with its large concentrations on higher altitude brings more green color.

Northern Lights Rare, all-red auroras are produced by high-altitude oxygen, at heights of up to 200 miles. Nitrogen produces blue or purplish-red aurora. The connection between the Northern Lights and sunspot activity has been suspected since about 1880.

Aurora Venusian auroras are produced by the impact of electrons originating from the solar wind and precipitating in the night-side atmosphere. An aurora was also detected on Mars, on 14 August 2004, by the SPICAM instrument aboard Mars Express. The aurora was located at Terra Cimmeria, in the region of 177° East, 52° South.

Aurora Australis During wintertime in the Southern region of our earth, people anticipate the occurrence of southern lights in the night sky. These southern lights are called Aurora Australis, which are caused by the passing solar wind in the atmosphere of the southern polar region and then captured by the earth’s magnetic field.

- 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 –

Northern Lights in Reykjavik The Northern Lights are generated in the upper atmosphere as it gets bombarded by electronically charged particles from the sun. They form what is known as ‘auroral belts’ around the geomagnetic poles and occur high above the Earth's surface, at altitudes between 100-250km, where the atmosphere is extremely thin.

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.

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.

- A significant portion of Sweden lies within a zone (called the ‘auroral oval’), where solar particles collide with gases in the earth’s atmosphere to create colourful ribbons of light known as the northern lights, or aurora borealis.

What causes the aurora borealis? The colors in the aurora were also a source of mystery throughout human history. But science says that different gases in Earth’s atmosphere give off different colors when they are excited. Oxygen gives off the green color of the aurora, for example. Nitrogen causes blue or red colors.

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.

- When charged particles from the solar wind collide with air molecules above Earth's magnetic poles, it causes the air molecules to glow, causing the auroras — the northern and southern lights. Editor's note: This article was updated on September 29, 2015, to correct the percentages of elements in Earth's crust.

Aurora Gallery The aurora borealis or northern lights are caused by a complicated set of interactions between the solar wind and Earth's magnetic field. Recent developments in satellite and ground observations now make it possible to forecast space weather near Earth resulting from disturbances on the sun.

- 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.

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.

What are the Northern Lights? 1 Then, as these charged particles excite gases in our atmosphere, they make make them glow - just like gas in a fluorescent tube.  The solar wind can cause the Earth's magnetic field lines to disconnect from our planet. When these field lines snap back into position, charged particles from the solar wind are again pushed into the Earth's atmosphere, causing aurora. The more magnetic field lines that disconnect and snap back, the further south the Northern Lights can be seen.

What is the Aurora Borealis? Auroras are the result of collisions between gaseous particles (in the Earth’s atmosphere) with charged particles (released from the sun’s atmosphere). Variations in colour are due to the type of gas particles that are colliding. The most common aurora colour which is green, is produced by oxygen molecules located about 60 miles above the earth.

- Aurora Borealis are more common in northern latitudes, such as the northern states or Canada. Iceland and Scandinavia see them frequently as well. The cause is a stream of … high-energy electrically charged particles from the Sun, often emitted during a solar flare or coronal mass ejection (CME).

- In this region of the atmosphere the Sun's energy is so strong that it breaks apart molecules and atoms of air, leaving ions (atoms with missing electrons) and free-floating electrons. The ionosphere is the region of the atmosphere where the aurorae occur.

Northern Lights What causes the Northern Lights? 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. Variations in colour are due to the type of gas particles that are colliding.

- 1 The solar wind can cause the Earth's magnetic field lines to disconnect from our planet. 2  When these field lines snap back into position, charged particles from the solar wind are again pushed into the Earth's atmosphere, causing aurora. 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.
