万圣节过后,NASA公布了一段时长30分钟的太阳4K视频,给人们带来一种前所未有的震撼。

11月1日,NASA公布了一段时长30分钟的太阳4K视频,给人们带来一种前所未有的震撼。这段视频的画面由NASA的太阳动态观测卫星(SDO)拍摄。SDO于2010年2月11日发射,每天24小时对太阳进行观测。

这段视频画面由NASA的太阳动态观测卫星(SDO)拍摄。SDO于2010年2月11日发射,每天24小时对太阳进行观测。NASA介绍称,SDO捕捉到的画面涵盖了太阳10种不同的波长,每种都显示了太阳物质的不同温度。反过来,太阳物质的不同温度能标示太阳活动,如太阳耀斑、日冕环等。

         太阳活动往往会对地球产生影响,耀斑和另一种名为日冕物质抛射的太阳风暴有时甚至能扰乱人类的太空活动。SDO拍摄的这些影像有助于研究者更好地理解保持太阳恒久运动的电磁系统的复杂性,让他们拥有了一个全新观察地球跟太阳关系的角度。

             The Sun is always changing and NASA's Solar Dynamics Observatory is always watching. Launched on February 11, 2010, SDO keeps a 24-hour eye on the entire disk of The Sun, with a prime view of hte graceful dance of solar material coursing through The Sun's atmosphere, the corona.

       SDO captures images of The Sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. Different temperatures can, in turn, show specific structures on The Sun such as solar flares, which are gigantic explosions of light and x-rays, or coronal loops, which are stream of solar material travelling up and down looping magnetic field lines.

       Scientists study these images to better understand the complex electromagnetic system causing the constant movement on The Sun, which can ultimately have an effect closer to Earth, too. Flares and another type of solar explosion called coronal mass ejections can sometimes disrupt technology in space. Moreover, studying our closest star is one way of learning about other stars in the galaxy. NASA's Goddard Space Flight Center in Greenbelt, Md. built, operates, and manages the SDO spacecraft for NASA's Science Mission Directorate in Washington, D.C.
