你能看到多少个太阳黑子？中央图像显示了在2025年发生的许多太阳黑子，每个月都围绕着圆圈，并在中央大图像中聚集在一起。每一个太阳黑子都被磁冷却，因此看起来是黑暗的，并且可以持续几天到几个月。虽然这些特色图像来自美国宇航局的太阳动力学观测站，但用装有太阳滤光片的小型望远镜或双筒望远镜就能很容易地看到太阳黑子。非常大的太阳黑子群，比如最近的AR 4366，甚至可以用日食眼镜看到。太阳黑子仍然是通过肉眼来计算的，但总数并不被认为是准确的，因为它们经常变化和分裂。去年，也就是2025年，恰逢太阳活动极大期，这是11年太阳活动周期中磁场活动最强烈的时期。我们的太阳在很多方面仍然是不可预测的，包括它什么时候喷出会影响地球的太阳耀斑，以及下一个太阳周期会有多活跃。

How many sunspots can you see? The central image shows the many sunspots that occurred in 2025, month by month around the circle, and all together in the grand central image. Each sunspot is magnetically cooled and so appears dark -- and can last from days to months. Although the featured images originated from NASA's Solar Dynamics Observatory, sunspots can be easily seen with a small telescope or binoculars equipped with a solar filter. Very large sunspot groups like recent AR 4366 can even be seen with eclipse glasses. Sunspots are still counted by eye, but the total number is not considered exact because they frequently change and break up. Last year, 2025, coincided with a solar maximum, the period of most intense magnetic activity during its 11-year solar cycle. Our Sun remains unpredictable in many ways, including when it ejects solar flares that will impact the Earth, and how active the next solar cycle will be.
