Extreme events - including massive ejections of material from the sun's corona - have been known to disrupt power lines and trigger widespread blackouts on earth.
人们知道，极端情况——包括太阳日冕的大量物质喷发——会破坏地球的供电线路，从而引发大面积停电。
What's more, a decrease in sunspots doesn't necessarilymean a drop in other solar features such as prominences, which can produce aurora-triggering coronal mass ejections.
而且，太阳黑子减少并不一定意味着太阳的其它特征的减少，比如日珥——它能产生引起极光的日冕物质抛射。
Giant eruptions from the sun called Coronal mass Ejections cause "space weather storms" which, if large enough, could lead to massive disruption of electric grids on Earth.
