The Shadow of an Atom

For the first time ever, scientists have captured an image of a shadow thrown by a single atom. In this case, the atom is an Ytterbium ion, trapped in a vacuum and cooled down to only a few ‘millikelvin’ (which is VERY cold).

Researchers captured the image using their custom-built ion trap, which was also responsible for capturing the highest-resolution image of a single atom previously.

The question is, how many atoms do you need to cast a shadow? Scientists found that it only takes one! Learn more here.
