This article notes that the electrodes are 2 mm apart:

Zooming in on the photo there, let's say the atom takes up 1/20th of the width, so that would put it at 100 micrometers, or 1 million Angstroms.  This site says the width of a Strontium atom is 4.38 Angstroms, likely measured by packing a bunch into solid form:

So yeah, it looks 250,000 times bigger than you'd expect, probably because of all kinds of effects like the light spreading out, the limited resolution of the camera's sensor, and motion of the atom.

I saw this news on my twitter feed and thought - I know that name from Dlang. I don't know you personally but I have a background in material science. Very well done!

It's by definition possible because... David's done it.
