The number of sunspots on our sun typically ebbs and flows in a predictable 11-year cycle, but one unusual 70-year period when sunspots were incredibly rare has mystified scientists for 300 years. Now, a nearby sun-like star seems to have paused its own cycles and entered a similar period of rare starspots, according to a team of researchers at Penn State. Continuing to observe this star could help explain what happened to our own sun during this "Maunder minimum" as well as lend insight into the sun's stellar magnetic activity, which can interfere with satellites and global communications and possibly even affect climate on Earth.
