NASA听到高能粒子撞击磁场的“地球之歌”
据国外媒体报道,隶属于美国国家航空航天局的辐射带风暴探测器(RBSP)于今年8月30日成功发射,该探测器在9月5日捕获到了地球磁层发出的无线电波“声音”,酷似啁啾声或者吹口哨声,科学家们认为这是地球外层磁场区域受到了太阳风粒子的撞击。该声音被称为“地球之声”,就如同地球在进行大合唱,并且可以被人类的耳朵听见。
位于地球磁层外的神秘辐射带,内外辐射带区存在不同的高能粒子分布情况,来自美国爱荷华大学的科学家克雷格·克勒特则因(Craig Kletzing)认为我们已经知道地球磁场发生如此神奇的现象已经数十年了,如果用无线电接收机将其录制下来,那么听起来就像是鸟鸣般的声音。位于地球磁场上部的高能粒子行为可释放出“地球之声”,而美国宇航局的辐射带风暴探测器由两个探测器组成,处于环绕地球的椭圆轨道上,近地点高度为375英里,而远地点为2万英里以上。科学家通过这两艘探测器旨在研究地球外围神秘的范艾伦辐射带,探索高能辐射层对近地空间的影响。
In our opinion, the source of such powerful and immense manifestation of acoustic-gravity waves must be very large-scale energy processes. These processes include powerful solar flares and huge energy flows generated by them, rushing towards Earth's surface and destabilizing the magnetosphere, ionosphere and upper atmosphere. Thus, the effects of powerful solar flares: the impact of shock waves in the solar wind, streams of corpuscles and bursts of electromagnetic radiation are the main causes of generation of acoustic-gravitation waves following increased solar activity.
Given the surge in solar activity as manifested itself in the higher number and energy of solar flares since mid-2011, we can assume that there is a high probability of impact of the substantial increase in solar activity on the generation of the unusual humming coming from the sky. It should be pointed out that solar activity began to rise sharply since early 2011, with its amplitude significantly higher than all forecasts given by a number of influential scientific institutions in 2010 and 2011. Meanwhile, the observed increase in solar activity is fully consistent with the forecast of the International Committee GEOCHANGE published in the Committee's Report in June 2010. If this growth rate of solar activity continues, its amplitude by the end of 2012 will be higher than the amplitude of 23rd solar cycle, and in 2013-2014 the solar activity will reach its peak the amplitude of which was predicted by us to be 1.5 - 1.7 times higher than the amplitude of the 23rd cycle.
