此视频从不同波段记录了金星出入凌的详细过程,非常精彩!不容错过!原文如下: Ultra-high Definition View of 2012 Venus TransitOver a six-hour period on June 5-6 2012, the Solar Dynamics Observatory (SDO) collected images in many wavelengths of one of the rarest predictable solar events: the transit of Venus across the face of the sun. These transits occur in pairs eight years apart that are separated from each other by 105 or 121 years. The last transit was in 2004 and the next will not happen until 2117. 金色的太阳来自171埃紫外波段,红色的304埃,品红色的1700埃,橙色的则来自过滤可见光。304埃和171埃反应的是太阳大气层景象,可见光波段是看不到的。(1埃米等于十分之一纳米)
