Where are aurora's located in the atmosphere?
Auroras are typically located in the Earth's atmosphere in the polar regions near the magnetic poles. The Northern Lights or Aurora Borealis occur near the North Pole, while the Southern Lights or Aurora Australis appear near the South Pole. These phenomena are caused by solar wind particles interacting with the Earth's magnetic field.
How far is the Aurora burualis from the earth?
The Aurora Borealis, or Northern Lights, are typically located around 60 to 75 miles above the Earth's surface. However, they can sometimes occur at altitudes up to 200 miles.
How does an aurora develop?
The aurora borealis (northern lights) form when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. These collisions result in countless little bursts of light, called photons, which make up the aurora.
What is the meaning of constellation corona borealis?
The constellation Corona Borealis is commonly known as the Northern Crown. It represents the shape of a crown or circlet, with a curve of stars making up the outline. The name "Borealis" means "northern" in Latin, referring to its position in the northern celestial hemisphere.
Who assisted anders Celsius?
Anders Celsius was assisted by Olof Hiorter, a Swedish botanist and physicist. Hiorter helped Celsius in setting up the Uppsala Astronomical Observatory and also provided guidance in his research on the aurora borealis.
Where are some good places to view the Aurora Borealis in Sweden?
We saw an awesome Aurora Borealis in Goteborg. Our ship was tied up alongside the Volvo company. Lots of good views. Friendly and happy people showed us a pretty good timel
Does aurora borealis have any bad effect on human and the world?
The aurora borealis (northern lights) does not have any direct negative effects on humans or the world. In rare cases of extreme solar activity, it may interfere with certain forms of technology such as satellite communications or power grids. However, for the most part, it is a natural phenomenon that poses no harm.
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 was aurora borealis discovered?
The Aurora Borealis, or Northern Lights, is a natural phenomenon, just like sunshine, rain, snow, clouds, and so on. Auroras are normally caused by particles emitted from the sun that eventually reach the atmospheric particles that are located high above the earth, giving them an electrical charge that causes them to glow. People who live in the northern latitudes have always noticed them; they didn't have to be "discovered." All they need to do is look up in the sky and they'll see the Aurora Borealis when they are present.
Where are aurora's located in the atmosphere?
Auroras are typically located in the Earth's atmosphere in the polar regions near the magnetic poles. The Northern Lights or Aurora Borealis occur near the North Pole, while the Southern Lights or Aurora Australis appear near the South Pole.

The Aurora Borealis, or Northern Lights, are typically located around 60 to 75 miles above the Earth's surface. However, they can sometimes occur at altitudes up to 200 miles.
How big is the Aurora Borealis?
The Aurora Borealis doesn't have a set size or color- it is a phenomenon caused by electrons produced by the sun exciting the atoms in Earth's atmosphere. It can be as large as a huge ribbon stretching across the sky to the tiniest thread; it all depends on the sun.

What are the northerners?
Northern lights is the name of a light phenomenon (aurora borealis) often seen in northern regions. The lights have been around since Earth formed an atmosphere, the dinosaurs saw it, early humans saw it and our descendants will see it. The scientific name for the phenomenon is "Aurora Borealis", aurora for short. Go as far north as you can go for the best views and you must be away from ambient lighting for a decent view. Charged particles from the Sun are accelerated by the Earth's magnetic field and the collisions these particles have with atoms of Nitrogen and Oxygen in the upper atmosphere (60 - 90 km up) excite the electrons of the atoms, when the electrons fall back to a lower excitation state they emit light we see this light as the aurora.
What would happen if you fell in the aurora borealis?
The aurora borealis is the closest thing to "nothing" that you can actually see; it is VERY thin air, partially ionized by the solar radiation spiraling in toward the Earth along the magnetic field lines. It is, for the most part, above the highest altitude that aircraft can reach. If you were to go up in a high-altitude balloon and jump out with a space suit and a parachute, you could "fall into the aurora borealis" and suffer no ill effects. Without the space suit, you would be dead in moments from lack of air, and without a parachute, you would be killed on impact with the ground 30 miles below.
What is another name for the Aurora Australis?
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 Hemisphere. These silent 'fireworks' you often see on a clear winter night in a variety of shapes and colours! Sometimes the Aurora Australis is over 100-250 km above the ground. The aurora forms huge oval halos of radiation around the earth's magnetic poles.The auroras can disrupt power systems, navigation systems, communications, and more.An Aurora Australis 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 collide with atoms of the oxygen and nitrogen gases in the ionosphere and the particles glow creating curtains of blue, green and magenta. An aurora is sometimes accompanied by a crackling sound.Like the Aurora Borealis (northern lights) but in the southern hemisphere.
What is the display of southern lights?
The Southern Lights, also known as the Aurora Australis, are just like the Northern Lights, or Aurora Borealis. They result from charged particles from the sun that are deflected by the earth's magnetic field, which is strongest at the poles, which are where most of these charged particles end up.
