As Auroras Boreal e Austral As Auroras Boreal e Austral As auroras são tempestades magnéticas que ocorrem nas regiões polares. Na região do Pólo Norte ela é conhecida como Aurora Boreal, sendo Aurora a deusa romana da alvorada e Boreas, vento norte em grego. Na região do Pólo Sul ela é chamada de Aurora Austral, sendo que Australis quer dizer do Sul em latim. As Auroras Boreal e Austral ocorrem quando a Terra é atingida pelas partículas eletrostáticas emitidas pelo Sol em decorrência de suas reações termonucleares. Estas partículas, ou Vento Solar, são defletidas pelo campo magnético da Terra, a Magnetosfera. O vento solar flui em torno da magnetosfera de forma parecida como a água passa por uma pedra em um rio. Ele também pressiona a magnetosfera, fazendo distorcer o seu campo magnético que, ao invés de linhas simétricas como as de um ímã, passa a se esticar e alongar, gerando os incríveis desenhos em movimento que vemos no céu. : ENCONTRA-SE FOTOS DESTE SLIDE EM MEU ORKUT.MENEZES "OU PELO G.MAIL. andreluiz2006rj@gmail.com criador do slide....MUSICA ILUSTRATIVA:Vanessa da Mata - Onde ir Tags: ANDRE PRODUÇÕES |

Babylon A.D. Trailer 2013: Die Erde hat einen dritten Weltkrieg überstanden. Die Menschen leben mit neuen Energieformen und haben sich technisch entwickelt. Bevölkerungsexplosion, Umweltverschmutzung und Mafia-Brutalität sind schlimmer als in unserer Zeit. Aber man lebt. Toorop (Vin Diesel) ist einer von vielen Abenteurern, die sich fürs Töten oder andere gefährliche Missionen bezahlen lassen. Eines Tages heuert Mafiaboss Gorsky (Gérard Depardieu) den Söldner an. Er soll die junge, hübsche Aurora (Mélanie Thierry) und deren Vormund, die Nonne Rebecca (Michelle Yeoh), nach New York begleiten. Zuerst hört sich der Auftrag für Toorop nach einem Routine-Job an, doch schon bald muss er erkennen, dass sich die Eskorte zu einer bedrohlichen Angelegenheit entwickelt. Denn nicht nur Gorsky will Auroras außergewöhnliche Fähigkeiten für sich nutzen... Tags: Babylon A.D. Vin Diesel Action Kino Movie Trailer Concorde Mathieu Kassovitz Mélanie Thierry Michelle Yeoh |

THEMIS: Understanding Space Weather - Northern Lights. Introduction Blooming flowers, chirping birds and warmer weather are all signs that spring has arrived. But a lesser-known sign of spring are auroras, or the Northern Lights. For reasons not yet fully understood by scientists, the weeks around the vernal equinox are prone to auroras. But NASA is aiming to solve this mystery and others with a new mission to study the Northern Lights, called THEMIS. Nicky Fox, NASA scientist: These are just caused by energy coming into our Earth's magnetic atmosphere causing the whole magnetic field to reconfigure and end up with an explosive release of high-energy electrons and protons into our earth's atmosphere, where they strike the molecules, both oxygen and nitrogen and cause them to glow. Narrator: Besides igniting the northern lights, these substorms can create big problems here on Earth by disrupting power grids, satellites, air travel and even GPS signals. Spring is one of the best times to view the auroras because the substorms that spark them are more frequent in the months around the equinoxes. Plus the longer nights provide a great backdrop for these stunning displays. While auroras have fascinated observers for centuries, little had been known about their origin. But NASA's aiming to resolve this mystery with a new mission to study the northern lights, called THEMIS. The THEMIS mission uses 5 identical satellites, and a network of ground observatories to track and determine what triggers the auroras that occur during substorms. And since its launch just last year, THEMIS has made some important discoveries. David Sibeck, NASA scientist: Even in the first days of our mission we've used these five spacecraft and the dedicated array of ground observatories to track aurora racing westward across canada and alaska and time their motion and understand where they occur. As our knowledge about the northern lights continues to expand, pretty soon auroras may not seem so mysterious after all.

Glowing Color-Clouds 30 Min Before 2008 Sichuan China Quake These clouds seemed to be glowing or somewhat luminous and seemed to resemble some characteristics of the Auroras. An earthquake light is an unusual luminous aerial phenomenon, similar in appearance to the aurora borealis, that allegedly appears in the sky at or near areas of tectonic stress, seismic activity or volcanic eruptions. Scientific evidence for the presence of lights is sketchy, given that there are few references documenting the phenomenon. The lights are most evident in the middle period of an earthquake, although there are reports of lights that occurred after or even before the earthquake, as in the 1976 Tangshan earthquake. They usually have shapes similar to those of the auroras with white to bluish hue, but occasionally they have been reported to have a wider color spectrum. The luminosity is typically visible for several seconds, but there have been cases in which they lasted tens of minutes. In the 1930 Idu earthquake, lights were reported up to 70 miles from the epicentre.[1], although most lights are not so far away. There have also been cases in which electromagnetic waves caused by the earthquake interfered with radio transmissions, such as during the Great Chilean Earthquake of 1960. Distinguishing earthquake lights from other transient optical phenomena can be difficult during the chaos of a tremor. For example, a bluish-white flashes that are accompanied by loud bangs or hissing during an earthquake are more likely the result of electrical arcing in power lines or transformers.

En el espacio - 11 - Eclipses y auroras En este capítulo veremos... El eclipse total es uno de los fenómenos más espectaculares del sistema solar. Suele tardar un eclipse total de sol de unos tres minutos. Por la eclíptica de la Luna ligeramente inclinada a 23º da dos puntos de insercción de la eclíptica de la Tierra, es por esos puntos donde se producen los eclipses. Existen también los eclipses anulares de sol, ya que la luna se halla más lejos y no tapa todo el sol. Veremos con atención un eclipse total de Sol a tiempo real con máximos detalles como la perla de Barley y los diamantes de la corona solar. Algunos eclipses pude durar hasta siete minutos. Las auroras se producen en las latitudes más alta de ambos hemisferio, y gracias al viento solar, choca con el campo magnético terrestre, y las partículas obstruídas quedan atrapadas y se canaliza por los polos dando el fenómeno de auroras en los polos.
