As the process of fusion occurs inside the sun, it spews high-energy particles (ions, electrons, protons, neutrinos) and radiation in the solar wind. When the sun's activity is high, you'll also see large eruptions called solar flares and coronal mass ejections. These high-energy particles and radiations get released into space and travel throughout the solar system. When they hit the Earth, they encounter its magnetic field.

What is it called when particles from the sun strike atoms in the ionosphere near the poles?
The described activity causes the generation of the Aurora Borealis and the Aurora Australis.
What causes the Aurora borealis to end?
The sun
What from the sun causes the aurora borealis?
Solar Winds
How often does the Aurora occur?
Solar flares are ejected from the Sun every so often. It relates to solar activity on the Sun. They can occur at any time, but are more common at the peak of the cycle of solar activity and for about 3 years after the peak. The solar activity cycle takes about 11 years.
How are the Northern Lights - Aurora Borealis - related to the earth's magnetic field?
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 said to be accompanied by a crackling sound, but this has never been recorded and scientists are at a loss to explain what causes the sound.

Why don't we see aurora on the moon?
An aurora occurs when charged particles of the sun excite the electrons of atoms in Earth's atmosphere. The moon does not have an atmosphere.

What time is the Aurora in Norway?
The aurora does not work to a time table. Auroral displays occur following an eruption on the sun. A stream of protons is ejected from the sun and travels into space at very high speed. When they approach the earth, our magnetic field diverts them towards the (magnetic) north and south poles. When they enter the ionosphere they interact with the gases up there. This is what causes the glow of an aurora. When these events will occur is something that we don't (and can't) know. All we can say is that the more sunspot activity there is on the sun, the more likely an aurora is. The aurora is spectacular at night, but not bright enough to be seen in daylight. You are therefore more likely to see one in winter because the nights are longer.
What occurs during wilting?
The sun causes wilting. It is called extreme wilting.

Do the northern lights happen in antarctica?
Aurora are generated when magnetic storms from the sun hit the earth's atmosphere and interact with it. Both polar regions experience aurora: Aurora Australis occurs in the Southern Hemisphere, and Aurora Borealis occurs in the Northern Hemisphere.
How long does the Aurora Australis last?
Usually about one hour to two hours. A very faint Aurora lasts only a few minutes. Some auroras which are very strong otherwise known as "aurora storms" last for days, fading away and returning. It all depends on our sun's activity.
When does Aurora Borealis occur?
Aurora Borealis occurs in the northern hemisphere, and its companion, Aurora Australis in the Southern hemisphere.Both are caused by a torrent of charged particles from our Sun, and which are directed by the earth's magnetic poles towards those poles.This occurrence is most common during solar storms and sunspot activity, which occurs in an 11-year (or 22-yeaar) cycle.In intense solar storms, they may even be seen as far south in the USA as Texas, but very rarely. Under these conditions, the excess of charged particles can damage electrical and telephone wiring (and transformers), by causing large currents to flow.
