100 light years. That's how long the first radio wave has been traveling at the speed of light.

The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.

Naw I'm aware, I only said diameter because when I read it the blue dot represented the 200 light-year distance that the waves have traveled from endpoint to endpoint. It's a great read from Popular Mechanics.
