太陽爆最大耀斑 加拿大現壯美極光 [16P]
2012年3月8日，加拿大耶洛奈夫，五年來最大一次太陽耀斑活動將給地球大氣層帶來大量帶電粒子，耶洛奈夫地區因此出現壯美瑰麗的極光現象。加拿大西北部城鎮耶洛奈夫恰好位於本次極光發生地區，擁有非常好的極光觀測條件。

據美國媒體報導，美國當地時間6日晚太陽爆發了5年來最強烈的耀斑，產生的磁暴於美國東部時間8日7時抵達地球。

美國國家航空航天局（NASA）捕捉到了本次太陽耀斑和日冕物質拋射的視頻。據估計，本次日冕物質拋射不會直接擊中地球，但它產生的帶電粒子雲團可能從地球附近掠過。

當地時間2012年3月8日，NASA公布的圖片，太陽表面爆發了強烈耀斑，這是繼2011年8月最大規模耀斑爆發後最為嚴重的一次，耀斑爆發產生的強烈輻射和磁場將在五年內影響地球

This image combines three images with different, but very similar, temperatures


The dark areas - called coronal holes - are places where very little radiation is emitted, yet are the main source of solar wind particles


This picture highlights the outer atmosphere of the Sun - called the corona - as well as hot flare plasma

This flare was categorized as an X5.4, making it the second largest flare -- after an X6.9 on August 9, 2011 -- since the sun's activity segued into a period of relatively low activity called solar minimum in early 2007


This extreme ultraviolet wavelength image provided by NASA provides another look at a solar flare, which could also force airlines to reroute


This colour-coded image combines observations made by Nasa in several extreme ultraviolet wavelengths, highlighting a bright X-class flare toward the upper left on March 6

Solar flares are often associated with solar magnetic storms known as coronal mass ejections


The Sun in extreme ultraviolet light captures a dark coronal hole just about at the Sun's centre


Activity on the sun will peak next year

This picture shows what our eyes would see if we were able to dim the brightness of the sun, with sunspots clearly visible


This picture shows a web-like pattern of bright areas that highlight places where bundles of magnetic field lines are concentrated

Very pretty photos! 正！
