Space is expansive: looking up to the stars, it can sometimes feel like everything sits on a single, two-dimensional sheet held up above us. It doesn't, of course—so how do we measure how far away things are?
Ever try measuring the straight-line distance between two points on Google Maps? You had to hold some object or appendage up to the little scale, then eyeball-measure the distance on your screen. What a mess. No more—a new update puts the task a right-click away. Also, you can doodle with it.
