"Australia summed up in one picture"
Picture of a single atom.
"In the centre of the picture, a small bright dot is visible – a single positively-charged strontium atom. It is held nearly motionless by electric fields emanating from the metal electrodes surrounding it. (The distance between the small needle tips is about two millimetres.)
When illuminated with a specific shade of blue-violet laser light, the atom absorbs and re-emits photons sufficiently quickly for an ordinary camera to capture it in a long exposure photograph. This picture was taken through a window of the ultra-high vacuum chamber that houses the trap."
