When the winds reach the Earth’s magnetic field, they trigger reactions with gases such as oxygen and nitrogen and create photons or tiny explosions of light.

Three books and a political document (in Spanish) refer to a “battle in the sky” and a “volcanic eruption”, which commenced at the beginning of February and apparently lasted until the end of April. How long did Mars planetary dynamo take to turn off? Check out more images of the recent Aurora Australis at Ian Musgrave’s Astroblog.
Further evidence for a sighting of the aurora australis in Chile in 1640 has been gleaned from our search of relevant chronicles in both Spanish and Latin-American literature. In the sky, an aurora australis takes the shape of a curtain of light, or a sheet, or a diffuse glow; it most often is green, sometimes red, and occasionally other colors too.Like its northern sibling, the aurora australis is strongest in an oval centered on the south magnetic pole.
This is because they are the result of collisions between energetic electrons (sometimes also protons) and atoms and molecules in the upper atmosphere … and the electrons get their high energies by being accelerated by solar wind magnetic fields and the Earth’s magnetic field (the motions are complicated, but essentially the electrons spiral around the Earth’s magnetic field lines and ‘touch down’ near to where those lines become vertical).So by far the best place to see aurorae in the southern hemisphere is Antarctica!

Typically 100 to 300 km (this is where green is usually seen, with red at the top), but sometimes as high as 500 km, and as low as 80 km (this requires particularly energetic particles, to penetrate so deep; if you see purple, the aurora is likely to be this low).There’s a good aurora FAQ at this University of Alaska Fairbanks’ Geophysical Institute site (though it, naturally, concentrates on the borealis! by none. intersects the continents of North America, Europe, and Asia, allowing for the reverse is true for aurora borealis.Thanks to modern science and the efforts of explorers, we now know that auroras occur at both the North and South Poles.

Meanwhile in the Northern Hemisphere, Norse mythology explained the Aurora Borealis as the furious galloping of the Valkyries (ferocious and brave female warriors) across the star-paved night sky, their shining helmets, armour, and shields casting the gleaming colours out to illuminate the darkness. world did not get to observe the aurora australis until relatively recently.
Aurora australis, also referred to as the Southern Lights, occur as a result of fierce solar storms, which send solar winds rushing towards Earth.

This is due to the fact that auroras are generated by solar wind, the term used for the streams of particles emitted by the sun on a regular basis. However, because these countries are located well outside the Antarctic Circle, auroras in these places do not occur on any predictable timetable.
