Live Aurora Borealis
Enviado por Alisson S.
Sent by Alisson S.As auroras boreais serão transmitidas "ao vivo" por um site lançado nessa segunda-feira pela Agência Espacial Canadense (CSA, sigla em inglês). "Esperamos que a dança de luzes celestiais os incite a descobrir os segredos do céu, da terra e da ciência, com base nas interações entre a Terra e nossa própria estrela, o Sol", disse o presidente da CSA, Steve MacLean. Além de enviar todas as noites imagens de auroras boreais, o objetivo do site
www.asc-csa.gc.ca/auroramax é explicar como se formam as "luzes celestiais", os melhores pontos de observação e como fotografá-las, explicou MacLean.
As auroras boreais se formam nos polos, quando os ventos solares atingem a atmosfera terrestre. No Canadá, este fenômeno se produz entre agosto e maio.

Starting Monday night, live feeds of the aurora borealis will be available on www.asc-csa.gc.ca/auroramax, a website set up by the Canadian Space Agency.
A CSA spokeswoman says the light show will begin after dusk local time or at about 11:30 p.m. EDT. But if skywatchers can’t stay up, they can watch it the next day on video. The launch of the online observatory coincides with aurora season in Northern Canada, which generally begins in late August or early September and ends in May. Auroras occur as charged particles from the sun collide with gases in Earth’s upper atmosphere. The online observatory is a collaborative initiative involving the space agency, the University of Calgary, the city of Yellowknife and Astronomy North.
