The myths fear and awe concerning the aurora borealis
The particles from the solar wind must hit nitrogen atoms a lot harder in order to excite them. Myth, magic or science, the aurora borealis gives darshan across nations in the region.
This gives the gas atoms energy, which causes them to release both light and more electrons. Auroral particle acceleration[ edit ] The electrons responsible for the brightest forms of the aurora are well accounted for by their acceleration in the dynamic electric fields of plasma turbulence encountered during precipitation from the magnetosphere into the auroral atmosphere.
These fine displays occur at an altitude of from miles, while the lower limit is 40 miles and the upper limit is miles.
Because the highest atmosphere has a higher percentage of oxygen and is sparsely distributed such collisions are rare enough to allow time for oxygen to emit red. The northern lights belong to no one. Because northern lights appear over the polar areas for the most part, the ancient people in these areas have at best seen very few auroral outbreaks.
5 myths about the aurora borealis
From his own observations of the Aurora bending and his knowledge of the magnetic fields geometry, he concluded that these two phenomena had a near relation. Solar Wind is a stream of charged particles flowing outward from the Sun through the vacuum of space and crashing into anything in their path, including planets and any astronauts performing a space walk — note, this is a genuine threat to astronaut Tim Peake when he is outside of the protective shielding of the ISS. Yet, as spellbinding as aurora legends of distant cultures have been since ancient times, the scientific explanation for the lights adds even more intrigue to this phenomenon. The Inuit of Alaska believed that the lights were the spirits of the animals they hunted: the seals, salmon, deer and beluga whales. This illustration stems from Danzig in Germany now known as Gdansk, a town in the northern part of Poland. Labrador Inuit art — from the collection of the History Museum of Canada. Our century Kristian Birkeland is one of the key people in the auroral research. The Aurora is a magnificent and mystical-looking light show seen at night in the northern or southern hemisphere known as Aurora Borealis or Aurora Australis or the Northern and Southern Lights.
