Now today we are going to tell you about the Northern Lights (Aurora). Which is a wonderful phenomenon of nature. Here you will find the answers to all the questions about where and how this event takes place. Northern Lights (Aurora) is found in countries like Norway, Iceland, Alaska, Finland, USA, Canada, and Scotland.

What causes the aurora borealis?
The aurora borealis or northern lights are an ethereal display with colored lights that shimmer over the dark sky. What are the causes?
People who reside at or travel to high altitudes may occasionally see sparkling lights that shimmer in skies at night. There are some Inuit who believed that spirits of their ancestral ancestors could be observed dancing in the aurora. In Norse mythology, the aurora was believed to be an ancient fire bridge to the sky that was built by gods. The ethereal show – aurora borealis or aurora australis either the southern or northern lights – is stunning. What is the reason these lights appear?
Our sun is located 93 millimeters away. However, its impact extends well beyond the visible surface. Massive storms on the sun unleash solar particles flying across the sky. If Earth is located in the direction of this particle flow the magnetic field of our planet and atmosphere will react.
When charged particles of the sun hit atoms and molecules that are in the Earth’s atmosphere, they stimulate these atoms, which causes them to become brighter.
What country are the Northern Lights in?
The Auroral band spans Finland, Sweden, Norway, Iceland, Greenland, and Canada. We offer holidays to each of these countries, and each of our holidays is carefully designed so that you can maximize your chances to witness Auroral Lights. Northern Lights.
What does it mean for an atom to be excited?
Atoms are composed of a nucleus central to an electron-rich cloud surrounding the nucleus on an orbit. In the event that charged solar particles hit the Earth’s atmosphere electrons shift to higher-energy orbits, farther far away from their nucleus. When an electron is moved back to a low-energy orbit and releases a particle of light or photon.
The aurora is often seen as a series of lights however they could also appear as spirals or arcs, usually moving along lines of force in the Earth’s magnetic field. The majority of them are green however, there are occasions when you’ll see some pink and more intense displays that could feature violet, red and white hues. The lights are typically located in the north countries that border with the Arctic Ocean – Canada and Alaska, Scandinavian countries, Iceland, Greenland, and Russia. However, the bright displays of lights can also be seen in more southern latitudes of America. The United States. Also, the lights also are also visible in the Earth’s south polar regions.
The aurora’s colors were also a source of mysteries throughout the course of human history. However, science has proven that various gases in the Earth’s atmosphere emit various colors when exuberant. Oxygen is the gas that gives off the green hue of the aurora, as an instance. Nitrogen can cause red or blue hues.
Today, the aurora mystery isn’t as elusive as it once was. But people still travel miles to witness the stunning natural light show that is visible in the earth’s atmosphere. Even though we understand the science behind the aurora, this stunning natural light show can inspire us to imagine Gods, fire bridges as well as dancing ghosts.
Some Questions About The Northern Lights (Aurora)
What are the northern lights?
The northern lights, which is one of the astronomical phenomena known as the polar lights (aurora Polaris), are streaks of color or curtains of lights that appear occasionally during the evening sky.
The Polar light (aurora Polaris) is a natural phenomenon throughout the southern and northern hemispheres. The phenomenon can be truly amazing. Northern lights are also known according to their scientific names, for example, aurora borealis and southern lights are known as aurora australis.
Sten Odenwald is the author of The 23rd Cycle: learning to live with turbulent stars (New York: Columbia University Press, 2001) gives insight into the process by which northern lights are created:
The origin of aurora starts on the surface of sun as solar activity releases ejecta of gas. Scientists call it the coronal mass eruption (CME). If one of these hits the earth, in a period of two to three days, it will collide with the earth’s magnetic field. The field is invisible but if you could discern its form it could cause Earth to appear like the shape of a comet, with its long magnetic ‘tail’ that stretches over a million miles in front of Earth to the other side from the sun.
When an ejection of coronal mass collides in the direction of the magnetic field it triggers complex changes that occur to that region of the tail magnetic. These changes cause charge-driven particles that then flow along tracks of magnetic force to The Polar Regions. These particles are amplified in the upper atmosphere of Earth and, when they meet with nitrogen and oxygen atoms, they emit brilliant auroral lights.
Can I see them anywhere?
Yes, although they are more frequent at higher latitudes and places like Alaska, Canada, and Antarctica, closer to the Earth’s poles. Occasionally, they have been seen closer to the equator, and even as far south as Mexico. To view them, look in the direction of the closest pole (the northern horizon in the northern hemisphere, the southern horizon in the southern hemisphere).
Can I see them at any time of the year?
Yes. In some areas, such as Alaska or Greenland, they may be visible most nights of the year. And they occur at any time of the day, but we can’t see them with the naked eye unless it’s dark.
What causes the colors and patterns?
Colors and patterns are from the types of ions or atoms being energized as they collide with the atmosphere and are affected by lines of magnetic force. Displays may take many forms, including rippling curtains, pulsating globs, traveling pulses, or steady glows. Altitude affects the colors. Blue-violet/reds occur below 60 miles (100 km), with bright green strongest between 60-150 miles (100-240 km). Above 150 miles (240 km) ruby reds appear.
Fun Facts about northern lights
- According to Neil Bone (The Aurora: sun-earth interactions, 1996), the term aurora borealis–northern dawn–is jointly credited to have first been used by Pierre Gassendi (1592-1655) and Galileo Galilei (1564-1642), who both witnessed a light display on Sept. 12, 1621. However, Bone also includes a description of the northern lights made 1,000 years prior by Gregory of Tours (538-594.) It included the phrase, “… so bright that you might have thought that day was about to dawn.”
- Auroras have been observed since ancient times.
- The height of the displays can occur up to 1000 km (620 miles), although most are between 80-120 km.
- Auroras tend to be more frequent and spectacular during high solar sunspot activity, which cycles over approximately eleven years.
- Some displays are particularly spectacular and widespread and have been highlighted in news accounts. Examples include auroral storms of August-September, 1859, Feb 11, 1958, (lights 1250 miles wide circled the Arctic from Oregon to New Hampshire) and March 13, 1989, (the whole sky turned a vivid red and the aurora was seen in Europe and North America as far south as Cuba).
- Legends abound in northern cultures to explain the northern lights. Some North American Inuit call the aurora aquarist (“football players”) and say the spirits of the dead are playing football with the head of a walrus. Often legends warn children that the lights might come down and snatch them away.
- June 1896, Norwegian Kristian Birkeland, the “father of modern auroral science,” suggested the theory that electrons from sunspots triggered auroras.
- Yellowknife (Northwest Territories, Canada) is the capital for aurora tourism.
- The earliest known account of northern lights appears to be from a Babylonian clay tablet from observations made by the official astronomers of King Nebuchadnezzar II, 568/567 BC.
