Sep 15, · Also known as the Northern or Polar Lights, the natural phenomenon known as the Aurora Borealis takes the form of an often spectacular natural light show which occurs when electrically charged particles from the sun collide with gaseous particles already present in the Earth's likedatingus.comted Reading Time: 4 mins. The Aurora Borealis (commonly referred to as the Northern Lights) are the result of interactions between the Sun and Earth's outer atmosphere. The Aurora Australis is the southern hemisphere counterpart to the Aurora Borealis.
The bright dancing lights of the aurora are actually collisions between electrically charged particles from the sun that enter the earth's atmosphere. The lights are seen above the magnetic poles of the northern and southern hemispheres. They are known as 'Aurora borealis' in the north and 'Aurora australis' in the south.
Auroral displays appear in many colours although pale green and pink are the most common. Shades of red, yellow, green, blue, and violet have been reported. The lights appear in many forms from patches or scattered clouds of light to streamers, arcs, rippling curtains or shooting rays that light up the sky with an eerie glow. The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere.
Variations in colour are due to the type of gas particles that are colliding. The most common auroral color, a pale yellowish-green, is produced by oxygen molecules located about 60 miles above the earth. Rare, all-red auroras are produced by high-altitude oxygen, at heights of up to miles. Nitrogen produces blue or purplish-red aurora. The connection between the Northern Lights and sunspot activity has been suspected since about Thanks to research what is the rule for an unplayable lie in golf since wha 's, we now know that electrons and protons from the sun are blown towards the earth on the 'solar wind'.
Note: was International What does contingent beneficiary designation mean Year and the atmosphere was studied extensively with balloons, radar, rockets and satellites. The temperature above the surface of the sun is millions of degrees Celsius.
At this temperature, collisions between gas molecules are frequent what is aurora borealis commonly known as explosive. Free electrons and protons are thrown from the sun's atmosphere by the rotation of the sun and escape through holes in the magnetic field. Blown towards the earth by the solar wind, the charged particles are largely deflected by the earth's magnetic field. However, the earth's magnetic field is weaker at either pole and therefore some particles enter the earth's atmosphere and collide with gas particles.
These collisions emit light that we perceive as the dancing lights of the north and the south. The lights of the Aurora generally extend from 80 kilometres 50 miles to as high boeralis kilometres miles above the earth's surface.
Northern Lights can be seen in the northern or southern hemisphere, in an irregularly shaped oval centred over each magnetic pole. The lights are known as 'Aurora borealis' in boreaalis north and 'Aurora australis' in the south. Scientists have learned that in most instances northern and southern auroras are mirror-like images that occur at the same time, with similar shapes and colors. Because the phenomena occurs near the magnetic poles, northern lights have been seen as far south as New Orleans in the western hemisphere, while similar locations in the east never experience the mysterious lights.
However the best places to watch the lights in North America are in the northwestern parts of Canada, particularly the Yukon, Nunavut, Northwest Territories and Alaska. Auroral displays can also be seen over the southern tip of Greenland and Iceland, the northern coast of Norway and over the coastal waters north of Siberia. Southern auroras are not often seen as they are concentrated in a ring around Antarctica and the southern Indian Ocean. Areas that are not subject to 'light pollution' are the best places to watch for the lights.
Areas in the north, in smaller communities, tend knoen be best. Researchers have borexlis discovered that auroral activity is cyclic, peaking roughly every 11 years. The next peak period is Winter in the north is generally a good season to view lights. The long periods of darkness and the frequency of clear what is the chewing gum made of provide many good opportunities to watch the auroral displays.
Usually the best time of night on clear nights to watch for auroral displays is local midnight adjust for differences caused by daylight savings time. In Roman myths, Aurora was the goddess of the dawn.
In medieval times, the occurrences of auroral displays were seen as harbingers of war or famine. The Maori of New Zealand shared a belief with many northern people of Europe and North America that the lights were reflections from torches or campfires. The Menominee Indians of Wisconsin believed that the lights indicated the location of manabai'wok giants who were the spirits of commonpy hunters and fishermen.
The Inuit of Alaska believed that the lights were the spirits of the animals they hunted: the aurira, salmon, deer and beluga whales. Other aboriginal peoples believed that the lights were the spirits of their people. Northern Lights Borealiz are Northern Lights? What causes the Northern Lights?
