David Nadlinger, a quantum physicist at the University of Oxford, has done the impossible. He captured a picture of a single atom using a normal DSLR digital camera.
The atom in the picture comes from strontium, an alkaline earth metal. To capture the photo, Nadlinger captured the particle between two electrodes then bombarded it with light from a blue laser to cause it to glow.
Below we have magnified the part of the photo that contains the single-atom image.
