On Wednesday last week (September 6, 2017), the sun produced an unusually large solar flare. This flare results in an increased likelihood of auroras lighting up the night sky here on Earth. To learn more about how this works, let’s look at the timely middle grade book Stories of the Aurora: The Myths and Facts of the Northern Lights by Joan Marie Galat and illustrated by Lorna Bennett.
As the title suggests, Stories of the Aurora is a combination of science and folklore. On the folklore side are legends from Inuit, Norse, Greek, and other cultures. On the science side, readers learn about the Earth’s magnetic field, how the auroras form, how they behave, and the environmental effects of auroras.
It’s a surprisingly informative mix. For example, on page 18 we learn that the Sami (also called Laplanders) call the aurora “The Light You Can Hear.” This might not make sense until the sidebar on page 30, when we learn people for centuries have reported hearing crackling and hissing sounds during bright auroras. In 2012 scientists were able to verify the sounds and lights were related and began to piece together how they are created.
Auroras making sounds is just one of the cool things readers will discover in Stories of the Aurora. This award-winning title will surely light up the faces of youngsters interested in finding out more about their world.
