She was an integral part of the award-winning EarthSky radio series almost since it began until it ended in 2013.
Anybody can ask a question But its effects extend far beyond its visible surface. Nitrogen causes blue or red colors.So today the mystery of the aurora is not so mysterious as it used to be. It would be extremely difficult if not impossible to harness the light or the electrical current which causes the light since they're dispersed over a huge area. @catapillar - fair point, but St Elmo's fire is due to high local electric field (static charge build-up; presence of thunder, ...); the Northern lights are caused by solar wind penetrating the Van Allen belt. This means … Falling spacecraft. The lights typically are seen in the far north – the nations bordering the Arctic Ocean – Canada and Alaska, Scandinavian countries, Iceland, Greenland and Russia. The solar wind adds its own magnetic energy to that of the Earth and when they combine they can blow out electric wires and cables!. It can generate several hundred thousand megawatts of electricity. At that altitude over the pole it would be far more efficient to use solar panels. If not why? Aurora just west of Saskatoon, by Colin Chatfield. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under By using our site, you acknowledge that you have read and understand our Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Most are green in color but sometimes you’ll see a hint of pink, and strong displays might also have red, violet and white colors. However the energy output is only greater than the output at a certain temperature and pressure (which is the peak of the emmited light) and then as it hits surrounding matter, the surrounding matter cools the gases so they are no longer a plasma form. The best answers are voted up and rise to the top

Start here for a quick overview of the site Discuss the workings and policies of this site It can disrupt communication transmissions, and even damage power lines and transformers. Scientists think the new aurora forms when electric currents from space create folds and curls in Earth's atmosphere. When the electrons drop back to a lower energy state, they release a photon: light. Radio communications . Detailed answers to any questions you might have That's obviously going to be a better choice.The Aurora Borealis occurs in the thermosphere above the North Pole. @Floris also fair point (and taken) , I got called away before finishing the comment. Oxygen gives off the green color of the aurora, for example. But science says that different gases in Earth’s atmosphere give off different colors when they are excited.

The Earth's atmosphere actually expands slightly when aurorae are around. Using the northern lights as an energy souce would be great, the energy created by the nuclear fusion happening which emits the glow, is substantial. If yes how?A good measure of the power you could extract is the pressure exerted by the solar wind (which is the source of Northern lights). Image via NASA The aurora often appears as curtains of lights, but they can also be arcs or spirals, often following lines of force in Earth’s magnetic field. In Norse mythology, the aurora was a fire bridge to the sky built by the gods. Image copyright 2014 Tor-Ivar Næss. JEHTo subscribe to this RSS feed, copy and paste this URL into your RSS reader. Stack Exchange network consists of 177 Q&A communities including Electricity is used to When charged particles from the sun strike air molecules in Earth's magnetic field, they cause those molecules' atoms to become excited. The lights typically are seen in the far north – the nations bordering the Arctic Ocean – Canada and Alaska, Scandinavian countries, Iceland, Greenland and Russia. If Earth is in the path of the particle stream, our planet’s magnetic field and atmosphere react.When the charged particles from the sun strike atoms and molecules in Earth’s atmosphere, they What does it mean for an atom to be excited? Taylor Photography is Maine's premiere website for night photography workshops and fine art prints of astrophotography landscape and scenic/nature photography. Anybody can answer We were over Madrid when I saw it on the windshield, it crawls creepily around, static wicks on the wings discharge it, hopefully but you know this, sorry :)The aurora is not a fusion reaction, although the source of the solar wind (which gives rise to the aurora) is. Reisafjorden, Norway bathing in auroras. Atoms consist of a central What happens in an aurora is similar to what happens in the neon lights we see on many business signs.
Most aurorae occur between 90 and 130 km above sea level, but some, particularly the ray-like forms, extend to several hundred kilometers up. And even though we know the scientific reason for the aurora, the dazzling natural light show can still fire our imaginations to visualize fire bridges, gods or dancing ghosts.Jennifer Khordi captured this aurora over the Catskills of New York. Some Inuit believed that the spirits of their ancestors could be seen dancing in the flickering aurora. What causes them?Those who live at or visit high latitudes might at times experience colored lights shimmering across the night sky. Yet people still travel thousands of miles to see the brilliant natural light shows in Earth’s atmosphere.
