Aurora Borealis and Aurora Australis

Parent Category: Arctic Circle
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.
  The Aurora in the North is normally called 'the Northern Lights' or the 'Aurora Borealis'.
  Anywhere from a few seconds to hours.
No. The aurora has no conscience nor intelligence. It is a phenomenon resulting from the interaction of the solar wind and the Earth's magnetic field.
They look like colorful ripples accross the night sky. They include colors like blue, green, yellow, and all the shades and hughes in between.
Northern light are in the Thermosphere
Since there have been people living far enough north to observe the  Northern Lights since before recorded history, the best we can say  is "prehistoric".
answer 2. They differ only in their location. Borealis = northern hemisphere, Australis = southern hemisphere. Both are caused by incoming energetic particles from our Sun exciting the air molecules. NO (: Lol
The Northern Lights occur above the earth's magnetic pole, which moves around the polar regions. Sometimes this happens over the ocean. It is often in the north of Canada, though it can be seen for hundreds of miles south of that. The land is frozen tundra.
There is not a set amount of times. They occur because of unusual  activity on the sun. That can happen at absolutely any time. So you  could have it lots of times in one year and very few times in  another year. The activity on the Sun is unpredictable. When  astronomers do see some unusual...
Aurora borealis is another name for the Northern polar lights.
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.
Because the charged particles in the solar wind streaming from the sun are attracted to the magnetic poles.
Normally near the poles of the Earth but sometimes with really bad sun flares, all around the world!!
You may be able to see Aurora Australis from Southern  Argentina, but probably not from Borneo.   You would not be able to see Aurora Borealis from either  geography.
Sunspots and solar flares push out charged particles into space. These stream out and some, attracted by the earth's magnetic poles, collide with oxygen and nitrogen atoms in the ionosphere and produce light. These are the triggers for the Northern and Southern Lights.
Rainbows and Aurora are completely different phenomena and the colours produced through completely different methods. Rainbows happen when white light passes through a prism (rain drops act as a prism). The white light is made up of 8 distinct colours. We all probably remember the phrase Richard Of...
If the weather conditions are right .Yes.
It is proven not to be an out-of this world event.... it is more like the ozone layer braking up to cause it's particalls to make dust residues in the sky and the moon/sun light make it glow..... Hope this helped
planet like venus which has no magnetic field, have very irregular aurora.. unlike Earth, Jupiter, or Saturn, which have an intrinsic magnetic dipole field, have aurora in the shape of oval shaped crowns of light on both hemispheres. When the magnetic field of a planet is not aligned with the...
No, the lights occur high up in the ionosphere, more than 60 miles (90 km) above the surface of the earth.
Canada is the best place to view it
northern or southern lights
Northern lights is the name of a light phenomenon often seen in the northern regions. The lights have been around since Earth formed an atmosphere -the dinosaurs saw it, early humans saw it and our descendants will se it. The scientific name for the phenomenon is "Aurora Borealis", aurora for short....
They collide with atoms of oxygen and nitrogen in the ionosphere and colored light is emitted. These colored lights make up the Northern and Southern Lights, the Aurora Borealis and Australis.
There's an Aurora Borealis (Northern Lights) at the north magnetic pole and an Aurora Australis (Southern Lights) at the south magnetic pole.
I have seen Aurora Borealis there once. But I've also seen snow in San Francisco Bay Area in summer, so go figure. Generally, it's very rare at this latitude. And mostly cloudy skies and plenty of street illumination over a vast urban area aren't going to help you to see it better.
The northern lights cause humans to speak phrases. Examples include "Wow!", "Cool!", "Awesome!", "Holy cow!", ""Wudja look at that!", and "Cheese!". The effect is most noticeable among tourists and other temporary visitors to the polar regions. Permanent residents are essentially immune to the...
In the upper mesosphere and the lower thermosphere, gas particles become electrically charged. Because these charged particles are called ions, this part of the thermosphere is called the ionosphere. In polar regions these ions radiate energy as shimmering lights called auroras, usually in latitudes...
Pantalaimon is Lyra's daemon
mostly in January till March. but if your thinking of going there , its really beautiful!
Pascal's Law states that any pressure put on a liquid in an enclosed space is spread evenly throughout the whole space. An example is hydraulic brakes on a vehicle. Pressing the brake pedal puts pressure on the brake fluid under the pedal and this same pressure is then applied (at the end of the...
The interruption of the solar wind by the earth's magnetic field can produce charged particles which interact with the atmosphere to produce the aurora effect.
It hapens once a year in Alaska.
It depends on whether you're in the Northern Hemisphere or the Southern Hemisphere. There are two different names for the Auroras.Here they are:1) Northern Hemisphere, Aurora Borealis2) Southern Hemisphere, Aurora AustralisThe farther north you go, the more often these beautiful phenomena occur.I...
The Aurora Borealis (also known as the northern lights) is seen in the night time sky exclusively in the northern hemisphere. It is more prominently and frequently viewed at northern latitudes, but can be seen generally throughout the temperate regions north of the equator, especially during the...
The Northern and Southern Lights (Aurora Borealis and Aurora Australis).
yes it occurs in the ionosphere
No one can be said to have discovered a natural phenomena that has been known since before recorded time. 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...
In the northern parts of China, yes.
Yes, charged particles from the sun collide with oxygen and nitrogen atoms in the earth's ionosphere to cause the Northern and Southern Lights.
The National Library of Australia has a search of local newspapers where you can see the original reports. Here is a short extract from the Sydney Morning Herald of Monday 20 March 1950: Aurora Australis Seen Last Night A brilliant display of the Aurora Australis - southern lights - was visible in...
The Southern Lights (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...
the Auroras form in the earths poles which is south pole and north pole.
Not particularly... the aurorae borealis is always there in all colors, only it's usually too faint to see.
I wrote this alt and I've separated the questions so I'd like to trash it. Thanks.
There are no hard and fast limits. Auroras have been seen anywhere in the USA except Hawaii.
The Italian scientist Galileo Galilei (1564-1642) was the first to name the northern Aurora Borealis.Aurora is the goddess of the dawn.Borealis is the Latin word for North and Australis is the Latin for South.
Yes, frequently. The display of the aurora borealis isn't connected to the seasons. However, while auroras often OCCUR during the daytime, the faint light is difficult to SEE against the bright background of the sunlit sky. So we more often see auroras at night. And since auroras are usually high...
During the most active times of the Sun's 11-year cycle of emissions, so every 11 years. I think this year is one such.
The Northern Lights occur in space, and are visible from many countries north of the Equator: the farther north, the higher your chances of seeing them.
Three colors generally. The main color is green, then blue and finally red. It depends on what gas is involved and how high in the ionosphere the reaction takes place. Oxygen gives off green light usually, or sometimes browny-red.Nitrogen gives off blue or red.If the collisions take place high up...
The Aurora Borealis (Northern Lights) and the Aurora Australis (Southern Lights).
Typically, northern-tier states like Alaska, Maine or Minnesota, but in extreme cases, they have been observed as far south as Florida!
In a neon or florescent light fixture, the glow in the tube is caused by running an electrical current through a near-vacuum with some trace elements. The type of trace elements determines the color of the light. An aurora happens when a solar electromagnetic storm causes electrical currents to...
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....
Aurora Australis means "Southern Lights", the opposite to "Aurora Borealis" in the north. (Aurora was the Roman goddess of dawn, (similar to the Greek goddess Eos) and Australis is the Latin word for South.)The Aurora Australis are lights up in the sky that you can only see from the Southern...
The phenomenon of aurora is an interaction between the Earth's magnetic field and solar wind.. Storms on the Sun eject charges particles. These particles follow magnetic force lines to the earths polar regions. When the particles enter the upper atmosphere thes cause gasses there to glow.. Auroras...
Charged particles from solar storms on the sun collide with atoms of oxygen and nitrogen in the ionosphere of the earth, producing moving waves of colored lights.
No, the lowest they come is about 60 miles (100 km) up in the ionosphere.
No.They are caused by charged particle interactions in the high atmosphere, from the solar wind striking the atmosphere and exciting atoms within it. The atoms give off light - depending on the element and the altitude - and provide the stunning display we label as an aurora.
. 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.
Dona is the Spanish word for Lady, so Dona Aurora means Lady Aurora. This could refer to many different people. Philippine Senator Benigno "Ninoy" Aquino's mother was called Dona Aurora. There is also a flower: Mussaenda philippica Dona Aurora (white) the Beautiful white hybrid of Mussaenda - Dona...
The Northern Lights, also known as Aurora Borealis is caused by  collisions between electrically charged particles from the sun that  enters the earth's atmosphere. The type of gas particles that are  colliding result in the variations in color.
If you are looking up at the aurora borealis while you are walking, it would be possible for you to stub your toe on a rock. Otherwise, no. The Aurora Borealis works exactly the same as a fluorescent light; electrical currents running through the near-vacuum of the ionosphere. Except prettier.
The "Northern Lights" (or Aurora Borealis) and their 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 atmospheric layer.

The particle stays at rest a= f/m = 0; because force = qvB is zero if v=0.
They occur in the Mesosphere.
The REALLY bright one is Venus. Look just above and to the left of Venus, to see both Mars and Saturn.
im not sure if this is compeltely accurate, but I believe that the best month to see the northern lights is December
Yes, Aurora Australis are visible for all the months of no  sunrises.
You can always see it , weather permitting, but Fall is best.
the best place to see auroras is either Canada or northern Alaska and Greenland
  Because they are origonally seen in Canada but they are seen in the north or Canada so they are called the Northeren Lights.   Hope this helps!!!
Between 35 miles and 600 miles
No. They can come at any time. It is down to activity on the Sun, which is unpredictable. When there is unusual activity on the surface of the sun that is seen by astronomers, they can predict that the Northern Lights will be visible in a few days after that. That can happen at any time. There is no...
Aurora is a pinkish color.
This planetary phenomenon is as old as the solar system.
Small bubbles rise slowly because they have less gas inside them, compared to larger bubbles. The more gas, the faster they rise.

General Motors has a problem with the solder connections on their instrument clusters. It will have to be sent off to have it repaired or replace it with a used unit.
Your best chance is to head for Alaska, it's the only U.S. State far enough north.
Caused by the collision of charged particles directed by the magnetic field of earth. Mostly common in polar regions auroras are good astronomical sight at night.
