What phenomenon sometimes known as the northern lights?

Answer 1

The Aurora Borealis - Northern Lights (and the Southern Hemisphere's Aurora Australis) are caused by the interaction of Earth's magnetic field with the flow of highly-charged particles from the Sun (known as the "solar wind"). Collisions of these particles with atmospheric molecules causes energy emission as visible light.

Auroras are normally confined to polar regions, which are nearer the magnetic poles.

When magnetic storms occur on the Sun, when electrically charged particles (ions) from the corona and solar flares are added to the solar wind produced by the corona, the charged particles are accelerated by the Earth's magnetic field interact with the gases in the upper atmosphere and cause the gas molecules to emit light. Electrons in the molecules are excited to higher energy levels and then release photons when the fall back to lower energy levels.

A:When the ions from the sun first collide with air particles, each causes a different reaction, and each reaction causes a different color to explode. Neutral nitrogen particles will create a

purplish pink color, while ionic nitrogen transforms into a brilliant blue. If an ion crashes

into oxygen in a lower altitude, it becomes the most common aurora, a yellowish-green

color. If it however, collides with oxygen at a high level, it will create the rarest blood red

aurora.

A:An Aurora Australis or an Aurora Borealis occurs when streams of particles from the sun's solar winds hit the earth's atmosphere at an angle (as can only happen at the poles). These particles interact with the edges of the earth's magnetic field and when they collide with the gases in the ionosphere, the particles glow creating curtains of blue, green and magenta.

An aurora is sometimes accompanied by a crackling sound.

A:Auroras are caused by radiation from the sun, called solar wind, interacting with Earth's magnetic field. Since the magnetic field is strongest near the poles, that's the region where most auroras occur. A:Solar charged particles from the sun, which are normally radiated into space, sometimes get caught in the Earths magnetic field as they come into the upper atmosphere they react with other gases and produce coloured lights A:Auroras are caused by Solar Winds colliding with charged particles in the upper atmosphere.

Auroras also occur on other planets in our solar system. According to the Geophysical Institute of the University of Alaska:

If a planet has an atmosphere and is bombarded by energetic particles, it will have an aurora. Since all planets in our solar system are embedded in the solar wind, all planets are subjected to the energetic particle bombardment, and thus all planets that have a dense enough atmosphere will have some sort of aurora

They also state that the intensity of the aurora will be dependent on the strength of the planets magnetic field.

According to NASA some of the largest auroras occur on Jupiter (which has auroras larger than the diameter of Earth) and it is unusual in that solar winds are not required as Jupiter (and its moon Io) is able to create its own charged particles and an intense electric field at it's poles.

Currently NASA believe that volcanic activity on Jupiter's moon (Io) ejects oxygen and sulphur ions (O+ and S+) into Jupiter's spinning magnetic field. It is the rotation of this magnetic field that creates the very high electrical charge at Jupiter's poles.

This interaction of the electric field and the charged particles from Io ultimately causes the majority of Jupiter's aurora.

A:Auroras are caused by a stream of charged particles (mostly electrons, but some protons and a few other things) from the Sun getting trapped in Earth's magnetic field and interacting with the gasses in our upper atmosphere. The charges electrify the nitrogen and oxygen in the air and make them glow like a neon or fluorescent light bulb. When photons crash into gas nuclei, electrons can take up that energy. The energized electrons use the extra energy to jump out to higher energy levels around their parent nuclei. The atoms are said to be ionized. The energized electrons then release the extra energy and return to their original orbitals. The released energy is electromagnetic energy - it's light.

When these particles hit the upper atmosphere, they react with the atoms and molecules of the air and cause them to glow with the characteristic colours associated with the aurora.

A:They only appear when the Sun sends out solar wind and when they hit the Earth's magnetic field they are deflected towards the magnetic poles. As the high speed particles from the Sun interact with the gases in the upper atmosphere they cause fluorescence as the outer electrons of the gas molecules are bumped into a higher quantum level. They then jump down to their original quantum level and in doing so emit a photon of light. Millions of these jumps make a spectacular light show. This also happens on a few other planets in the Solar System. A:It is formed because of the magnetic field of earth. As charged particles from the sun collide with our magnetic field it makes light.

Produced by Collision of charged Particles from Earths Magnetsphere.

The liquid iron core present at the interior of our earth has created a magnetic field around it.Till then which has been subjected to massive bombardment with high energy solar radiation & other form of harmful cosmic rays. All these high energy charged particles are get trapped in van Allen radiation belts & in addition get reflected by the earth's magnetic field towards the pole where these particles interact with the earth's atmospheric components in form of a visible energy called the northen lights.

Answer 2

northern charged particles tapped in earth's magnetosphere produce spectacular aurora, know as th enorthern lighs in the northern lights in the northern hemisphere. satellites or even a space shuffle are in orbit.

hope it helped

Answer 3

Aurorae are produced by the collision of charged particles from Earth's magnetosphere, mostly electrons but also protons and heavier particles, with atoms and molecules of Earth's upper atmosphere (at altitudes above 80 km (50 miles)). The particles have energies of 1 to 100 keV. They originate from the Sun and arrive at the vicinity of Earth in the relatively low-energy solar wind. When the trapped magnetic field of the solar wind is favourably oriented (principally southwards) it connects with Earth's magnetic field, and solar particles enter the magnetosphere and are swept to the magnetotail. Further magnetic reconnection accelerates the particles towards Earth.

The collisions in the atmosphere electronically excite atoms and molecules in the upper atmosphere. The excitation energy can be lost by light emission or collisions. Most aurorae are green and red emissions from atomic oxygen. Molecular nitrogen and nitrogen ions produce some low level red and very high blue/violet aurorae. The light blue and green colors are produced by ionic nitrogen and the neutral nitrogen gives off the red and purple color with the rippled edges. Different gases interacting with the upper atmosphere will produce different colors, caused by the different compounds of oxygen and nitrogen. The level of solar wind activity from the Sun can also influence the color of the aurorae.[citation needed]

Answer 4

the northern lights is normally at night and you would only go and see it if you had the equipment and you know exactly what time it will be as it could be at any time

Answer 5

The auras you see in the sky is caused by a huge amount of solar winds colliding with our megnetosphere is what creates the beautiful lights that appear.
