Let’s Begin…

In 1944, amateur astronomer Hisako Koyama’s latest endeavor was sketching the sun’s shifting surface. She spent weeks angling her telescope towards the sun and tracking every change she saw with drawings. Little did she know, these drawings were the start of one of the most important records of solar activity in human history. Alex Gendler details the incredible legacy of Koyama's work.
