关于太阳黑子的传说有很多，每一种都表示了人类对未知的事情的揣测和恐惧。而实际上，黑子不过是太阳的一种活动而已。在太阳的光球层上，有一些旋涡状的气流，像是一个浅盘，中间下凹，看起来是黑色的，这些旋涡状气流就是太阳黑子。

Astronomers¹ are still learning about sunspots and about their affect on us, but believe that the spots on the sun, which were first observed through a telescope by Galileo in 1610, are electrical in nature. They base this belief upon the known effects that sunspots produce, and upon one astronomer's uncontested showing that sunspots are whirlwinds of electrified² matter that burst out in pairs from the sun's interior.

Sunspots vary in size from what appear to be small specks³ on the sun's surface, to at least 90,000 miles long, and 200,000 miles in length, and are visible on most clear days.

When sunspots release their electrical energy, they shoot beams of negatively charged electrons into space, some of which escape into the earth's atmosphere. These electrons create electrical effects, such as the aurora⁴ borealis, or Northern Lights, cause the disruption of radio transmissions, and increase the amount of ozone⁵ in the upper atmosphere. The additional ozone may absorb more than the usual amount of the sun's heat, which in turn may effect our weather.

The sunspot cycle, is a recurring⁶ 11-year period over which the number of sunspots fluctuates and corresponds to the number of sun flares⁷. An increase in the number of sun flares leads to an increase in the number of sunspots, and a decrease in the number of sun flares leads to a decrease in the number of sunspots.

Records of sunspots have only been kept for the last 100 years or so, leaving astronomers with little to back their research and much yet to discover about this phenomenon.
