这种我们称之为“日冕物质抛射”的太空来客进入大气层，破坏电网，烧毁变压器，进而烧毁我们的等离子显示屏和芯片。
These coronal mass ejections, as they're called, hit our atmosphere and can knock out power grids, cooking their transformers, which in turn knocks out our plasma screens and fries our chips.
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。
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.
黑子是太阳表面比较暗的区域，也叫活动区。那里经常发生耀斑和日冕物质抛射等剧烈的喷发现象。

他说，日冕层的大部分热量，很明显地仍是通过日冕层中应力磁场的强烈作用而释放出来的。
Most of the heat in the corona, said Klimchuk, is apparently still released by the snapping of stressed magnetic fields in the corona.
所以好好的享受这些美妙的太阳耀斑和日冕带来的太阳风吧，可能要经过相当长一段时间我们才能再次观赏到他们了。
So enjoy the current rash of solar flares and beautiful coronal mass ejections; it might be some time before we see a solar cycle like this again.
