Mystical Light Shows in The Skies The Magic Behind Auroras
Watching the playback quality for Owl City’s 2010 hit number, ‘Vanilla twilight’ on my Time Warner TV- I was mind blown; it compromised for your modern music videos with such a magnitude of emotion. The awe filled expressions from the cast including kids along with a dog; Shaquille O’Neal (The Shak) with his parting words of “take me with you”; The young couple in the end holding hands and Adam appearing regarding his grand piano inside a light house between. I just loved it! But, what impressed me essentially the most was when towards the end the sky shows started. Wondering if it was graphics animated with computerized effects I found out the aurora was really filmed at a location in Pittsburgh. Not knowing much about auroras or aurorae (plural for aurora), I did some investigation. Here are some in the interesting facts that I found:
It is called after the Roman goddess Aurora who flies between your skies during twilight and sunrise. ดูซีรี่ย์เกาหลี in the popular Roman gods, but she actually is the personification of dawn.Auroras don’t only exist in the northern magnetic poles. They also frequent in Australia, New Zealand and other parts of the southern hemisphere. The scientific term for northern lights or the aurora effect within the northern hemisphere is ‘aurora borealis’. In the southern magnetic pole, they may be termed as ‘aurora australis’.
The earliest sighting of your Aurora was recorded in 1621, if it was given the scientific name by Pierre Gassendi.
When auroras appear they swirl slowly (like how gases move) and change color. This is because all with the magnetic and electrical forces react with the other person in constantly shifting combinations. In fact Auroras were known as “dance with the spirits” inside the past. They appear in large circles and only around what is known the auroral oval. The color is decided by certain factors based on how auroras work.
Here’s how an aurora is created: Solar winds, which is, winds circulating within the sun’s environment cross the earth. These winds are caused by sun spots. Sunspots are dark areas of magnetic disturbance on top in the sun. It has been shown that during periods of maximum sunspot activity, the sun’s rays ejects the greatest concentration of charged particles. And it is do your best of utmost solar activity that auroras are likely to seem. Solar winds cross planet earth’s magnetosphere. The magnetosphere has highly charged varying magnetic and electrical fields. The solar wind follows the magnetic lines with the magnetosphere and tunnels down towards Earth’s atmosphere. The Earth’s atmosphere presents various gaseous particles that collide with the solar winds. When the particles from the Earth’s uppermost atmosphere collide with these heated winds, energy is exchanged. The gaseous atoms gain energy which is greater than precisely what is required. When this excessive energy is emitted, auroras are designed.
Different atoms emit different colors from the spectrum when these are excited. It also depends on in which the energy exchange takes place and exactly how distant from planet earth’s atmosphere could it be happening. The two main gases that interact with all the solar wind are oxygen and neon. When the electrons interact with oxygen atoms at the height of about 60 miles away through the Earth’s atmosphere creates a familiar green color. Whereas, oxygen atoms with an altitude of 200 miles far from us provide a red color. Ionic Nitrogen produces the blue illuminate to 150miles and neutral Nitrogen gives off the red-puple and also the rippled edges effect above 150 miles
There are numerous stories about sounds related to auroras, but there isn’t any recordings of auroral sounds. Scientists can’t acknowledge an amount produce sounds in the aurora.
