What are the Northern Lights?
The aurora’s origin begins on the sun’s surface when solar activity ejects a cloud of gas. Scientists name this a CME(coronal mass ejection). If one of these reaches earth between 2 to 3 days. It collides with the Earth’s magnetic field and the particles originating from the ionosphere travel at enormous speed. This field is invisible. And if you could notice its form, it would make Earth look like a comet with a lengthy magnetic ‘tail’ stretching a million miles behind Earth in the opposite direction of the sun.
When a coronal mass ejection slams with the magnetic field, it causes complicated changes to happen to the magnetic tail region. These shifts generate currents of charged particles, which then flow along lines of magnetic force into the Polar Regions. These particles are boosted in energy in Earth’s upper atmosphere. When they collide with oxygen and nitrogen atoms, they create breathtaking auroral light.
The characteristics play when the Northern Lights appear on Earth:
- Clear sky – no atoms for the particles to contradict with!
- Secondly, there need to be charged particles or “plasma” that can convey excess energy to the particles.
- There must to be a magnetic field that draws the particles.
- Also need a “battery” that can charge the particles. For example., On Earth, that source is the Sun.
- Finally, you need to transfer the energy from the source to the particles to charge the particles. And that the solar winds transport energy from the Sun to the particles.
- September is the best month to see the northern lights!
3 Best Places to See the Northern Lights Around the World
- Fairbanks, Alaska
Fairbanks is the largest and coldest city in the Interior region of Alaska and the second largest in the state. Fairbanks is one of Alaska’s best destinations. And visitors will find many palces watch spectacular northern lights coloring the night atmosphere during Aurora Season. With the summer daylight shining up to 24 hours a day. The subarctic summer filled with action and brimming with growth. In fact, from mid-May through mid-July Fairbanks experiences 70 straight days of daylight!
2. Tromso, Norway
Tromso, one of the most stunning parts of the earth and offer fantastic wildlife experiences as well as amazing night skies. Norway is for good reasoning that Alta is comprehended as the “City of the Northern Lights”. No stay there would be complete without a visit or an overnight stay inside the amazing Igloo.
