The woman who stared at the sun - Alex Gendler


0 Questions Answered

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.

Long overlooked, Hisako Koyama’s life and career are covered in several articles, as well as a more detailed scientific paper. You can also see a more detailed report on her solar observations, and how they have helped reconstruct the historical record. And though we have known about sunspots for a long time, we are only recently beginning to learn about their impact on the Earth and its climate.
