Regular readers of this blog know that I love a good scale bar. As a longtime devotee of the works of Edward Tufte, I find great joy in visual representations of quantitative data. On various Fridays here in The Scholarly Kitchen we’ve looked at ways to understand the size of everything from the entire universe to the quantum realm. Today, something in between — perhaps the universe is too large for you to grasp, so how about a look at our galaxy? As noted below, if the Milky Way was the size of the continental United States, the sun would be about the size of a red blood cell, and the earth about one-third the size of the coronavirus. And as with all good videos discussing the stars, it ends with a Carl Sagan quote!
