21、earchers,gather and analyze this datacoming from different locations of the Solar System.因此我跟一群研究者一起,收集并分析这些 来自太阳系不同位置的数据。04:36And by doing so,my research shows that,actually,solarstorms have a generic shape,and that this shape evolves assolar storms move away from the Sun.我的研究显示,实际上,太阳风暴都有一个普遍特征,这一
