Photo of A Single Floating Atom Was Captured With an Ordinary Camera

Using an ordinary camera, with the help of long exposure, a laser, and two electrodes to suspend the atom in the air, David Nadlinger successfully took a photo of a glowing atom.

The image won first prize in a science photo contest conducted by UK based Engineering and Physical Sciences Research Council (EPSRC).
The EPSRC explains how a single atom is somehow visible to a normal camera:
When illuminated by a laser of the right blue-violet colour, the atom absorbs and re-emits light particles sufficiently quickly for an ordinary camera to capture it in a long exposure photograph.
