Aurora Borealis and Aurora Australis
The Aurora Borealis and the Aurora Australis, sometimes called The Northern and Southern Lights, are natural light displays in the sky, usually observed at night, particularly in the polar regions. Auroras are most visible closer to the Poles due to the longer periods of darkness and the magnetic field.

Do the northern lights have anything to do with the Sun?
Yes. The Northern Lights are entirely dependent on charged particles (ions) that form what is called the "solar wind". This is a continual but varying release of charged particles from the Sun's superheated corona. When these ions are diverted by the Earth's magnetic field (near the poles), they collide with atoms in the upper atmosphere. This produces the energetic emissions that we see as a light show in the night sky.
What is the rarest color in the auroras?
The rarest color in auroras is blue. Blue auroras occur at higher altitudes than other colors, around 60 miles above the Earth's surface. They are less commonly seen compared to green and red auroras.
Who first saw Aurora borealis and when?
There has been much debate about who discovered the auroras, but ancient Chinese and Greek people have been studying these natural wonders for years, and the ancient Eskimos and Scandinavians have been known to reference them as early as 700 AD.
The person that actually brought everyone's attention to the auroras was Benjamin Franklin, even though a French astronomer Pierre Gassedni was credited for given the name of the aurora borealis (the Roman goddess of dawn, Aurora, and the Greek name for north wind, Boreas) in 1612.
Which part of the thermosphere causes the Aurora Borealis?
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.

What is the best time to see the Aurora Borealis?
There isn't really a schedule of auroras; they happen when a stream of charged particles from the Sun interact with the Earth's magnetic field. Watch the website at spaceweather.com and look for "coronal mass ejections"; bright auroras often follow about 2 days later. But they sometimes are visible without any warning, because the Sun is CONSTANTLY sending out masses of charged particles.
What does the aurora borealis look like?
From space; a colored halo or some ''glowing veigns''
On Earth they often look like green clouds. On RARE occaisions you get the stereo-typical ''curtain'' like aurora. Sometimes they are just thin glowing strips of light in the sky, and sometimes you can't really see them, because they flash really quickly for several flashes before stopping.
Can you call the manufacturer of Aurora shredder?
ISN'T THERE A WARRANTY? MINE is only 1 & 1/2 Months old???
HOW DO I CALL THE MANUFACTURER????
the northern lights are caused by magnetic energy being shot out of the passing through the earths atmosphere it also happen in the southern hemisphere because the atmosphere is weaker in these parts
When were the northern lights discovered?
The northern lights, also known as aurora borealis, have been observed for centuries. However, the discovery of the scientific explanation behind them dates back to the 19th century. The phenomenon originates from interactions between the Earth's magnetic field and solar winds.
Where is the best place in the Continental United States to see the Northern Lights?
Alaska. The Geophysical Institue of the University of Alaska at Fairbanks even have an
Aurora Forecaster page on their website.

What is the common name for Aurora borealis?
Northern Lights (or southern if in the southern hemisphere)
Northern lights
The Northern Lights, or Aurora Borealis, are glowing bands, circles and streams of colored lights that sometimes appear in the northern latitudes.
pretty much there lights that apear in the sky at a pecific time of year.
Do the charged particles emitted from the sun cause the Northern Lights?
Yes, charged particles emitted from the sun, known as solar wind, interact with the Earth's magnetic field and atmosphere to create the Northern Lights (aurora borealis) near the poles. When these charged particles collide with gases in the atmosphere, such as oxygen and nitrogen, it produces the colorful light display seen in the night sky.
