What is the Borealis effect?
Is aurora borealis English?
a pattern of coloured lights that are sometimes seen in the night sky in the most northern parts of the world: Northern Scandinavia is one of the most accessible places on earth to watch the aurora borealis.
What are the two types of Borealis?
In the north, the phenomenon is called the aurora borealis or the northern lights. In the Southern Hemisphere, it’s the aurora australis, or southern lights. The name is different and it turns out that the view from each pole can be different too.
What is another word for aurora borealis?

What is another name for aurora borealis?
Polar lights (aurora polaris) are a natural phenomenon found in both the northern and southern hemispheres that can be truly awe inspiring. Northern lights are also called by their scientific name, aurora borealis, and southern lights are called aurora australis.
Is Northern Lights harmful to humans?
The Northern Lights occur so high up in the atmosphere that they don’t pose any threat to people watching them from the ground. The aurora itself is not harmful to humans but the electrically charged particles produced could have some potentially negative effects to infrastructure and technology.
What causes aurora borealis?
When the electrons reach Earth’s thin upper atmosphere, they collide with nitrogen and oxygen molecules, sending them into an excited state. The excited electrons eventually calm down and release light, which is what we see as the aurora.

How often does aurora borealis happen?
“Active periods are typically about 30 minutes long and occur every two hours, if the activity is high. The aurora is a sporadic phenomenon, occurring randomly for short periods or perhaps not at all.”
Why is aurora borealis only in the north?
Of the two poles, the aurora can be seen the strongest near the arctic circle in the Northern Hemisphere. The reason that the Aurora can only be seen at the poles has to do with how the Earth’s magnetic field acts. The Earth has a metal core and acts much like a bar magnet with two poles and a magnetic field.
Who was the goddess aurora?
In Greek legend, Eos, or Aurora, the goddess of dawn, falls in love with the mortal Tithonus, son of King Laomedon of Troy. According to the Homeric Hymn to Aphrodite, Aurora prevailed on Jupiter to grant the young human immortality, though later realized that she failed to stipulate his eternal youth in this request.
What country is the aurora borealis in?
The Northern Lights can be seen in many countries in the polar north: Norway, Greenland, Iceland, Swedish and Finnish Lapland, Scotland, Siberia, Canada and Alaska. Generally, the higher the latitude, the better the chance of experiencing the aurora.
Does aurora borealis make noise?
What is clear is that the aurora does, on rare occasions, make sounds audible to the human ear. The eerie reports of crackling, whizzing and buzzing noises accompanying the lights describe an objective audible experience – not something illusory or imagined.
What two things make up the aurora borealis?
The aurora borealis (Northern Lights) occurs when a coronal mass ejection (CME), a massive burst of solar wind and magnetic fields, interacts with elements in the earth’s atmosphere.
What language is Borealis?
The word borealis is Latin for boreal, which simply means “northern.” The aurora borealis is not the only aurora on Earth. The aurora in the Southern Hemisphere is called aurora australis or the southern lights.
What language is aurora borealis?
The word Aurora is Latin for sunrise and the name of the Roman Goddess of the dawn, and Borealis is the Greek name for the north wind, so Aurora Borealis means “dawn of the north” which is the name Galileo gave to the lights in 1619.
Can you see northern lights with naked eyes?
Auroras appear to the naked eye as a very faint, white glow in the night sky to the magnetic north. Many auroras are totally invisible to the naked eye or can only be seen by looking at them indirectly, i.e. out of the corner of your eye. It is extremely rare to see them in colour with the naked eye.
What will happen if you touch Northern Lights?
The aurora is emitted between 90 and 150 km in altitude (i.e. mostly above the ‘official’ boundary of space, 100 km), so ungloving your hand inside an aurora would likely be fatal (unless a fellow astronaut immediately reattaches your glove and repressurizes your suit).
