Its cool to visualize a little bubble around the Solar System that represents the 100 or so years we've been emitting radio waves into space. The signal would be very faint (power falls as 1/r^2) but visually if you zoom out on the milky way its a tiny little bubble around our system that barely reaches into our home galaxy. It's a humbling visualization.
