The Science Behind Edmonton's Northern Lights


What Causes the Northern Lights to Appear in Edmonton and Other Parts of the World

The Science Behind the Northern Lights

The Northern Lights, also known as Aurora Borealis, are a natural phenomenon that occur in polar regions of the world including Edmonton. This dazzling display is caused by charged particles from the sun colliding with atoms and molecules in Earth's atmosphere. These particles are carried to Earth by solar wind – a stream of charged particles constantly blowing outwards from the sun.

When these charged particles collide with gas molecules high up in Earth's atmosphere, they transfer their energy to them, causing them to emit light. The color of this light depends on which gas molecule was hit and how much energy was transferred. For example, collisions with oxygen atoms typically cause green or red lights while collisions with nitrogen produce blue or purple tones.

The Role of Earth's Magnetic Field

Earth's magnetic field plays an important role in creating the conditions for northern lights to appear. Our planet has a strong magnetic field that stretches far into space and acts like a shield against most of the solar wind streaming towards us from the sun.

However, some of these charged particles can slip through gaps in our magnetic field and enter our upper atmosphere near the poles where it is weaker. As they collide with gas molecules at high altitudes above 60 miles (100 km), they create spectacular displays of light – dancing curtains or arcs often accompanied by other shapes like spirals or rays.

The History and Cultural Significance of the Aurora Borealis

Indigenous Cultures and Folklore

The northern lights, or aurora borealis, have captivated people for centuries, inspiring myths and legends around the world. In indigenous cultures of North America, the northern lights played a significant role in shaping folklore and spiritual beliefs. For example, in some Inuit communities, it was believed that the spirits of their ancestors were dancing in the sky when the auroras appeared. The Cree people also had stories about the northern lights as a powerful force that could bring good luck or misfortune depending on how they were treated. These cultural beliefs illustrate how important this natural phenomenon is to these communities.

Historical Records

Historical records from various parts of Europe describe sightings of bright celestial displays that are believed to be early observations of an auroral display. However, it wasn't until Galileo Galilei coined the term "aurora borealis" after Aurora Roman goddess of dawn and Boreas Greek god of north wind in 1619 AD that scientists began studying this phenomenon more closely.

Modern Scientific Understanding

Today we know that Northern Lights occur when charged particles from solar flares collide with gas molecules in Earth's atmosphere causing them to emit light at different wavelengths resulting into beautiful colors like reds greens blues yellows pinks purples etc.. Scientists use satellites to monitor space weather conditions which help predict when strong displays will occur so tourists can plan their trips accordingly.

Overall it’s fascinating how throughout history humans have sought explanations for such spectacular events while not knowing what caused them but now thanks to modern scientific understanding we know much more about them including their historical significance among different cultures!

How Scientists Study and Predict the Behavior of the Northern Lights

The Northern Lights, also known as Aurora Borealis, are a natural phenomenon that have fascinated humans for centuries. While their beauty is undeniable, scientists have also been working hard to understand the science behind this colorful display in the sky. In order to study and predict the behavior of the northern lights, scientists use various tools and methods.

One important tool used by scientists is satellite technology. Satellites can provide an overall view of geomagnetic activity over large areas. This helps researchers determine where auroras are likely to occur and how they will behave once they do appear. Satellite imagery also allows scientists to track changes in magnetic fields around Earth which affect the creation of auroras.

Another useful method for studying northern lights is ground-based observation stations called Magnetometer arrays. These instruments detect small fluctuations in Earth's magnetic field caused by solar winds interacting with our planet’s magnetosphere which causes disturbance leading towards Aurora formation.

In addition to these tools, there are other technologies utilized such as All-Sky Cameras designed specifically for capturing images of Auroral displays from a specific location on earth at different wavelengths like green or red depending on wavelength filters installed on it; Ionospheric sounding techniques that measure electric currents within ionosphere layer above 100 km altitude where Auroras form their visible light patterns.

By combining data from all these sources - satellites, magnetometers & cameras -scientists can better predict when and where auroras will be visible with high accuracy thus making them popular tourist destination spots throughout Canada during peak viewing times especially Edmonton due its location close proximity near Magnetic North Pole.

Overall, Scientists continue researching ways to improve upon predicting Auroral activity so tourists visiting Edmonton can experience one of nature's most beautiful phenomena first-hand while simultaneously increasing understanding about space weather patterns affecting our planet every day!

The Best Times and Places to See the Northern Lights in Edmonton

Best Times to See the Northern Lights in Edmonton

The best time to see the northern lights in Edmonton is during winter, from November to March. During these months, the sky is usually clear and dark enough for optimal viewing conditions. It's important to note that even if you're visiting during this period, there's no guarantee that you'll be able to see the aurora borealis.

Another factor that can affect your chances of seeing the northern lights is solar activity. When there are high levels of solar activity, also known as a geomagnetic storm or a coronal mass ejection (CME), it increases your chances of seeing an intense display of lights.

To keep track of solar activity and increase your chances of seeing the northern lights, you can check websites such as or download apps like AuroraWatch.

Best Places to See the Northern Lights in Edmonton

If you want to see a good display of northern lights within city limits then try going somewhere with low light pollution like Elk Island National Park which has been designated as Canada's largest Dark Sky Preserve by Royal Astronomical Society Canada.

However, if you're willing to take a short drive outside Edmonton then there are other options available too! One popular location for watching auroras just 45 minutes east from downtown would be Miquelon Lake Provincial Park where people go stargazing all year round due its low light pollution environment making it perfect place for those who love outdoor activities including camping and hiking!

There are also several lodges and resorts located few hours away from downtown which offer guided tours specifically designed around viewing this breathtaking phenomenon under expert guidance. Some examples include Pine Lodge Resort near Slave Lake or Churchill Wild Eco-Lodges situated on Hudson Bay coast where guests stay in eco-friendly cabins surrounded by pristine wilderness while enjoying once-in-a-lifetime opportunities sighting polar bears along with stunning views over vast stretches Arctic tundra at night when skies come alive with dancing colors green/pink hues above them.

Tips for Capturing Photos of Northern Lights

Capturing photos of northern lights requires some preparation beforehand so here are some tips:

  • Bring tripod stand: Since long exposure photography will be required especially if capturing still images without any movement then make sure bring sturdy tripod stands so camera remains stable throughout entire shoot duration.

  • Use wide-angle lens: A wide-angle lens helps capture more area than usual lenses thus allowing better coverage area per shot thereby increasing probability getting 'that' shot!

  • Set ISO Low: Setting ISO setting low reduces noise/graininess associated higher values resulting cleaner looking pictures overall.

  • Turn off Flash & Other Light Sources: Turning flash off prevents unwanted shadows being casted onto subject while turning other sources light help reduce glare reflection surfaces surrounding scene.

  • Be Patient & Wait For Right Moment To Click That Perfect Shot!: This might sound obvious but patience key photographing auroras since they can appear suddenly disappear just as fast! So don't give up easily keep trying until get desired result finally hits jackpot!

The Impact of Solar Activity on the Appearance of the Northern Lights

The Connection between Solar Activity and the Northern Lights

The northern lights, also known as auroras, are caused by charged particles from the sun colliding with Earth’s atmosphere. These charged particles, primarily electrons and protons, are carried to Earth by solar wind – a stream of plasma released from the sun’s corona. When these charged particles collide with atoms and molecules in Earth's atmosphere, they excite them to higher energy levels. As these excited atoms return to their normal state, they release energy in the form of light – creating beautiful displays of colorful lights that dance across the sky.

The appearance of the northern lights is closely linked to solar activity. The sun goes through an 11-year cycle during which its magnetic field flips polarity. At times when there is high solar activity (such as during a solar maximum), more charged particles reach Earth's atmosphere resulting in brighter and more frequent auroras.

The Impact on Edmonton's Souvenir Industry

Edmonton has become well-known for its prime location for viewing the northern lights due to its close proximity to one of Canada’s largest dark-sky preserves - Wood Buffalo National Park. As such, tourism related businesses have been able to capitalize on this phenomenon by offering tours specifically geared towards viewing the auroras.

However, because solar activity impacts how often or bright these displays occur it can be difficult for tour operators or souvenir shops to guarantee customers will see them during their visit. This uncertainty can impact revenue streams significantly; some tour companies offer multiple nights out just so customers have a better chance at seeing something spectacular.


In conclusion, the northern lights phenomenon in Edmonton is a natural wonder that should be preserved and protected for future generations. The science behind this beautiful display of light is fascinating, as it involves charged particles from the sun colliding with gases in Earth's atmosphere. These collisions produce stunning colors and patterns that awe locals and tourists alike. It's important to remember that human activity can have negative effects on our planet's environment, including interfering with the delicate balance required for auroras to occur. By taking steps towards sustainability and reducing our impact on the environment, we can continue to enjoy Edmonton's northern lights for years to come.
