How Do Auroras Form? Auroras are formed when charged particles that are emitted from the sun hit the Earth's magnetic field and the atoms in the atmosphere. This interaction causes the gases in the atmosphere to give out...

How are the colors of the aurora created? The otherworldly colors of the Northern Lights and Southern Lights have fueled folklore for millennia, but their cause is actually quite straightforward. The aurora is caused by the interaction of high-energy particles (usually electrons) with neutral atoms in earth’s upper atmosphere.

- Cold, northern places, or Antarctica for the southern aurora. The lights occur most often and with greatest intensity in areas known as auroral zones. Seen from space, these appear as oval-shaped rings with each magnetic pole roughly in the centre.

ASTRONOMY FOR KIDS Aurorae happen on other planets, too, like Jupiter and Saturn (shown above). This is a false color image of Saturn courtesy of NASA. Oxygen molecules that can be found in the Earth’s atmosphere make green or brown-ish aurorae, whereas nitrogen molecules make the blue or red aurorae.

- The lights are seen around the magnetic poles of the northern and southern hemispheres. Auroras that occur in the northern hemisphere are called ‘Aurora Borealis’ or ‘northern lights’ and auroras that occur in the southern hempishere are called ‘Aurora Australis’ or ‘southern lights’.

Welcome to The Aurora Page The Aurora Borealis was slightly visible right after sunset and very active G4 storm at 9:00 -11:00pm EST. The storm was caused by a Coronal Mass Ejection or CME that exploded off the sun, for several hours the storm was rated a G4-Class storm with a KP of 8.

What Are Northern and Southern Lights? An aurora is a natural electric phenomenon that creates bright and colorful light displays in the sky. They are common at higher latitudes, mostly within the Arctic and the Antarctic Circles. Aurora borealis in Michigan, USA. The northern lights can be green, pink, red, blue or violet in color. ©iStockphoto.com/Constance McGuire. In the Arctic Circle, they are known as aurora borealis or the northern lights, while in the Antarctic Circle they are called aurora australis or the southern lights. These dramatic and colorful lights are created when electrically charged particles from solar winds enter the Earth’s atmosphere and interact with gases in the atmosphere.

In which layer of the atmosphere do the Auroras occur? The aurora borealis and aurora australis occur in the Ionosphere from around 100 km up. This layer of the atmosphere is also called the Thermosphere.53 people found this useful.he Aurora Borealis and its southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermos … phere, the outermost actual atmosphere.

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 Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (thermosphere/exosphere) due to Earth's magnetic field, where their energy is lost.

Aurora Borealis: What Causes the Northern Lights & Where to See Them As the temperature on its surface rises and falls, the sun boils and bubbles. Particles escape from the star from the sunspot regions on the surface, hurtling particles of plasma, known as solar wind, into space. It takes these winds around 40 hours to reach Earth. When they do, they can cause the dramatic displays known as the aurora borealis. [Infographics: How the Northern Lights Work & Anatomy of Sun Storms & Solar Flares] Auroras occur not only on Earth, but also on other worlds in our solar system (and perhaps exoplanets as well).

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.

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.he 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. 2  Red-oxygen, above 150 miles in altitude. 3  Blue-nitrogen, up to 60 miles in altitude.

How does the aurora borealis (the Northern Lights) work? There are times, though, when the lights are farther south, usually when there are a lot of sunspots. Sunspot activity follows an 11-year cycle. The next peak will occur in 2011 and 2012, so opportunities to see auroras outside their normal range should be good.he 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. 2  Red-oxygen, above 150 miles in altitude. 3  Blue-nitrogen, up to 60 miles in altitude.

Thermosphere - overview The aurora (Northern Lights and Southern Lights) mostly occur in the thermosphere. The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet. Temperatures climb sharply in the lower thermosphere (below 200 to 300 km altitude), then level off and hold fairly steady with increasing altitude above that height.

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.

What Causes the Aurora Borealis? During great magnetic storms, another type of red aurora can occur at altitudes as high as 180 to 240 miles. This type of aurora can be attributed to another excited state of atomic oxygen, and can be very spectacular and widespread.

- 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.

The aurora is caused by the interaction of high-energy particles (usually electrons) with neutral atoms in earth’s upper atmosphere. This process is similar to the discharge in a neon lamp, or the fluorescence of a television screen. The strongest auroras are quite bright, comparable to moonlight.

Aurora Images of the aurora australis and aurora borealis from around the world, including those with rarer red and blue lights. An aurora is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions.uroras result from emissions of photons in the Earth's upper atmosphere, above 80 km (50 mi), from ionized nitrogen atoms regaining an electron, and oxygen atoms and nitrogen based molecules returning from an excited state to ground state.

Enchanted Learning Search The magnetopause is the boundary between the area in which the Earth's magnetic field dominates and the magnetic field of the rest of the Solar System dominates. Charged particles become trapped on the field lines of the magnetosphere. Auroras appear when trapped particles from the solar wind spiral towards a pole.

In which layer of the atmosphere do the Auroras occur? The Aurora Borealis and its southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermosphere, the outermost actual atmosphere. Above this layer, the exosphere has so few molecules that they can escape into space.
