Episode Details

In today's image, we see a video clip comparing solar activity at minimum (left) and maximum (right). The Sun goes through an 11 year cycle of solar activity with a peak of activity every 11 years. The more active the Sun is, the more we see solar flares and auroral activity here on Earth.

My podcasts are available in video form through this YouTube Channel.
