How auroras form Auroras occur when charged particles (electrons and protons) collide with gases in Earth’s upper atmosphere Those collisions produce tiny flashes that fill the sky with colourful light As billions of flashes occur in sequence, the auroras appear to move or ” dance ” in the sky
What causes the aurora borealis?
The lights we see in the night sky are in actual fact caused by activity on the surface of the Sun Solar storms on our star’s surface give out huge clouds of electrically charged particles The aurora’s characteristic wavy patterns and ‘curtains’ of light are caused by the lines of force in the Earth’s magnetic field
What happens if you touch the aurora borealis?
The aurora is emitted between 90 and 150 km in altitude (ie 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)
Where does the aurora Borealis occur?
They occur most frequently in a belt of radius 2500 km centered on the magnetic north pole This so-called auroral zone extends over northern Scandinavia, Island, the southern tip of Greenland and continuing over northern Canada, Alaska and along the northern coast of Siberia
Does aurora Borealis happen every night?
There is no official season since the Northern Lights are almost always present, day and night Caused by charged particles from the sun hitting atoms in Earth’s atmosphere and releasing photons, it’s a process that happens constantly
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
What is Arora?
The Arora is a community of Punjab, comprising both Hindus and Sikhs The name is derived from their native place Aror Historically, the Arora section of the Khatri community had been principally found in West Punjab, in the districts to the south and west of Lahore
Why shouldn’t you whistle at the northern lights?
Don’t whistle at the Northern Lights Alerted to your presence, the spirits of the lights will come down and take you away Having said that, North American Indians often whistled at the Northern Lights to encourage them to come closer so they could whisper messages that would then be taken to the dead
Is the aurora borealis hot?
The northern lights look like fire, but they wouldn’t feel like one Even though the temperature of the upper atmosphere can reach thousands of degrees Fahrenheit, the heat is based on the average speed of the molecules
Do aurora borealis make sound?
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
Which country has the best northern lights?
What are the best places to see the Northern Lights? Tromso, Norway Based in the heart of the aurora zone in the Norwegian Arctic, the city is widely regarded as one of the world’s best places to see the Northern Lights Swedish Lapland Reykjavik, Iceland Yukon, Canada Rovaniemi, Finnish Lapland Ilulissat, Greenland
What are 2 fun facts about the aurora borealis or northern lights )?
1 Aurora is the Roman goddess of dawn and Boreas is the Greek term for the north wind, hence the name Aurora Borealis 2 The International Space Station sits at the same altitude as the Northern Lights meaning astronauts can see the lights from the side
Can you see the northern lights with the naked eye?
Yes Most commonly the aurora seen will be green or whitish, but depending on the strength of the activity, pinks and reds are also visible to the naked eye
How long do northern lights last?
A good display may last for no longer than 15-30 minutes at a time, although if you’re really lucky, it could extend to a couple of hours or longer To see the Northern lights, the sky needs to be dark and clear of any clouds Some people claim the aurora comes out when temperatures are colder
What month is best to see the northern lights?
But here’s the good news: The time is right to get a glimpse of the aurora borealis Thanks to longer hours of darkness and clear night skies, December through March is usually the best time to observe this elusive natural phenomenon (though you can sometimes see the northern lights starting as early as August)
Who discovered the Northern Lights?
The 17th century astronomer, physicist and philosopher, Pierre Gassendi, saw the Northern Lights on a trip in the North and named them the Aurora Borealis
Why aurora happens in polar region?
Description: Aurora is sometimes referred to as ‘polar light’ It is predominantly seen in the regions of high altitudes like the Arctic and Antarctic An aurora is caused by the streams of electrified particles (which are emitted by the sun) trapped in the magnetic field of the earth
How Southern Lights are formed?
The famous Northern and Southern Lights — Aurora Borealis and Aurora Australis for those Latin lovers among us — are caused by high-energy particles from the Sun cascading down on Earth As they near our planet, they interact with Earth’s magnetic field, which channels them toward the north and south magnetic poles
What is aurora in sky?
An aurora is a colorful light show in the sky caused by the Sun Auroras happen when particles from the Sun interact with gases in our atmosphere, causing beautiful displays of light in the sky Auroras are often seen in areas near the North Pole or South Pole These lights are called auroras
