A very recent achievement in solar research is the ability to detect sunspots on the invisible far side of the sun . this is done through tracing sound waves that bounce between different depths of the sun
最近一项有关太阳研究的成就是，科学家可以通过一种称为日震学的技术，追踪在太阳内不同深度反弹的声波，从而侦查到位于太阳背著地球一面的黑子。
The technique , called helioseismology , is similar to the use of seismic waves for detecting underground features on earth . being able to reveal features beneath the surface of the sun , helioseismolgy has contributed a lot to modern understanding of the sun . it is becoming also an important tool for studying the solar - terrestrial relations
日震学和以地震波侦查地球内部构造的方法相类似，科学家利用日震学研究太阳内部的结构，使我们对太阳有更多的了解，而日震学亦成为研究日地关系越来越重要的工具。
