The magnetic activity of stars like sun, which is the root cause of the sunspot cycle, is still poorly understood even after decades of intense study.

磁场的变化是像太阳这样的恒星表面黑子活动周期的根源，尽管经过几十年的认真研究之后，地球人仍然对其知之甚少。

Sunspot activity, which follows an 11-year cycle, is due to peak in 2013 after which it will start to wane slightly.

虽然以11年为周期的太阳黑子活动将在2013年达到顶峰之后，将缓慢衰落。

But in the current cycle, sunspot activity has collapsed.
