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.
689 Questions
In which layer of the atmosphere do the Northern Lights occur?
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. Above this layer, the exosphere has so few molecules that they can escape into space.
(see the related question below)
What is the Aurora Borealis more commonly known as?
The Aurora Borealis is more commonly known as the Northern Lights. This natural light display is seen in the high-latitude regions of the northern hemisphere.
Where do the colours come from in the northern and southern lights?
The colors in the northern and southern lights are created by charged particles from the sun interacting with gases in the Earth's atmosphere. These gases emit different colors when they are hit by the charged particles at high speeds. Oxygen produces green and red colors, while nitrogen produces blue and purple colors.
What is the cause of glowing colors in the pole atmospheres?
Glowing colors in the polar atmospheres, known as the auroras, are caused by charged particles from the sun interacting with gases in Earth's atmosphere. When these particles collide with gases like oxygen and nitrogen, they emit light in different colors depending on the type of gas and the altitude of the collision.
The Aurora borealis and Aurora australis occur in which layer of the atmosphere?
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.

Where in the US will you see the Aurora borealis?
The Aurora borealis, also known as the Northern Lights, can be seen in states along the northern border of the United States such as Alaska, as well as occasionally in states like Minnesota, North Dakota, Montana, and Washington. The further north you are, the better your chances of witnessing this natural phenomenon.
What colors are in the Southern Lights?
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 then oxygen gives off red. Lower down oxygen gives green and nitrogen shines blue and red. Lower down still oxygen is quiet and nitrogen still gives off blue and red.
When are Auroras most likely to occur?
Auroras are most likely to occur during periods of high solar activity, known as the solar maximum. This typically happens every 11 years. Additionally, auroras are more commonly seen during the winter months when nights are longer and darker.
Who came up with the name for the Aurora Borealis?
- 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.
Auroras form in the Earth's upper atmosphere when charged particles from the Sun interact with the Earth's magnetic field. These particles collide with gas molecules, creating a beautiful light display known as the Aurora Borealis in the Northern Hemisphere and the Aurora Australis in the Southern Hemisphere.
What is the cause of the Southern Lights?
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 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.
In Antarctica, you can see aurora australis, or the southern lights. You can read more by following the link, below.
Who discovered the northern lights?
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 regions.
Natural phenomena such as the Aurora Borealis have been in existence for millions of years, from times before people existed.
Auroras, also known as the Northern and Southern Lights, are natural light displays in the Earth's sky, predominantly seen in high-latitude regions near the poles. They are caused by charged particles colliding with the Earth's atmosphere, creating dazzling displays of colors and shapes like curtains, arcs, and coronas.
The Aurora borealis is seen mainly?
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 equinoxes (near spring and fall).
.
The Aurora Australis is the southern hemisphere's counterpart to the Aurora Borealis.
Where do Auroras usually occur?
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 Borealis
2) Southern Hemisphere, Aurora Australis
The farther north you go, the more often these beautiful phenomena occur.
I live in Minnesota, so I have to check the news or meteorologists to see the
rate of occurrence.
Hope this was helpful. Bye!
What is the aurora borealis and where is it located?
The aurora borealis, also known as the northern lights, is a natural light display in the Earth's sky, predominantly seen in high-latitude regions near the Arctic. It is caused by solar particles interacting with the Earth's magnetic field and atmosphere, creating colorful patterns of light.
In what four months are auroral displays most often seen?
Auroral displays are most often seen in the months of March, April, September, and October. These months correspond to the equinoxes when solar activity tends to produce more intense geomagnetic storms.
Who are Lyra's daemons in Northern Lights?
In the book "Northern Lights" by Philip Pullman, Lyra's daemon is named Pantalaimon, also known as Pan. Pan frequently shape-shifts into different animal forms and serves as a physical representation of Lyra's emotions and conscience.
What layer do Auroras occur in?
Auroras occur in the thermosphere, which is the second-highest layer of Earth's atmosphere. The thermosphere is located between the mesosphere and the exosphere, at an altitude ranging from about 80 km to 600 km above the Earth's surface.
In which layer of the atmosphere do the Auroras occur?
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 above 50 degrees.
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.

Can you see the Aurora Australis from Tasmania?
Yes, it is possible to see the Aurora Australis from Tasmania, especially in the southern parts of the island. However, clear skies, minimal light pollution, and strong solar activity are necessary factors for optimal viewing conditions.
Do the northern lights make a sound?
No, the northern lights do not make a sound. The light display is a result of charged particles from the sun interacting with the Earth's atmosphere, and there is no relation to sound production.
What is the effect of the northern lights on humans?
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 influence.
The event is called the aurora borealis or the northern lights. When particles from the sun enter the Earth's atmosphere near the north pole and interact with oxygen and nitrogen atoms in the ionosphere, it results in a beautiful light display in the sky.
What is Aurora counterpart role?
There's an Aurora Borealis (Northern Lights) at the north magnetic pole and an Aurora Australis (Southern Lights) at the south magnetic pole.
