THE Northern Lights are known as one of the most spectacular natural phenomena on earth.
But how does the color spectrum magically illuminate the sky? Here’s what we know.
What Causes the Northern Lights?
The Northern LightsAlso called Aurora Borealis, are the result of electrically charged particles from the Sun striking gaseous particles in our planet’s atmosphere.
this solar flare is often accompanied by a coronal mass ejection – a huge ejection of plasma from the Sun’s outer layer.
The Sun’s massive outburst of material is triggering a geomagnetic storm that is taking the aurora to lower latitudes.
The solar storms cause bright, colorful dancing lights of white, green, pink, and purple to light up the sky and is considered an incredible sight.
Color variations occur when different types of gas particles collide with the charged particles.
The aurora’s most common color is green, formed when oxygen molecules react with the particles about 60 miles above the ground, while nitrogen causes a blue or purple hue.
Why are the northern lights only in the north?
The Northern Lights are known for gracing the northern hemisphere – hence their name and the region’s fame.
but the phenomenon also occurs in the southern hemisphere, as it occurs at the north and south poles of the earth near the Arctic Circle.
Both are affected by the behavior of the Earth’s magnetic field, as both poles are attracted to the planet’s metallic core.
The show of light to the north is known as Aurora Borealis and to the south Aurora Australis.
Are the Northern Lights bad?
“The Northern Lights pose no threat to people enjoying them from Earth and are considered one of the seven natural wonders of the world.
However, the stunning play of light is caused by a solar storm – the one temporary disturbance of the earth’s magnetic fieldcaused by radiation and currents of charged particles from the sun.
This has the ability disturb the earth’s atmospheredisrupt radio signals, power grids and cause aurora shifts.
It could also interfere with satellite signals, which can experience “orientation irregularities”.
The Earth’s magnetic field helps protect us from the more extreme effects of solar flares.
Not only do they cause problems for our technology on Earth, but they can also be fatal to an astronaut if they cause injury or interfere with mission control communications.
Scientists have warned that the sun can produce bursts of solar radiation called “superflares.”
Just one of the Superflares could wipe out all technology on Earth – potentially causing trillions of pounds worth of damage and wreaking havoc on the planet.
What is the difference between northern and southern lights?
There is little difference between the various auroras other than their location and that the aurora are often easier to see.
The Northern Lights appear at the North Pole while the Southern Lights appear at the South Pole.
Storms of sun light up the sky with bright, colorful lights of white, green, pink, and purple and are considered an incredible sight.
The lights are visible from Earth as the aurora is pushed to lower latitudes as a result of the solar storm.
Which country is the best place to see the Northern Lights?
Norway is considered the best country to see the Northern Lights.
Tromso, Norway is a popular travel destination for great Northern Lights viewing.
They usually appear from September to April.
It is only a three and a half hour flight from London and a city also known for its pubs and bars.
The Nordic countries are considered the best places to see the Northern Lights.
If you want to go somewhere else, you can also visit Sweden.
Kiruna offers visitors a wilderness adventure and the lights can be seen between October and March.
Iceland and Canada are also good places to visit the Northern Lights.
