Not exactly up there with say the Hubble deep field photo.

Please post a weblink, or a summary of the paper.
In any case, all I did was state a fact, meaning that you cannot actually 'see'
an electron orbiting in the way the misleading heading implied.

well, I read the abstract,enough to show me that the authors' goal was NOT
to image "an electron".
There are already many successful experiments manipulating single
electrons by observing evidence of their location. Sherlock Holmes would
have been delighted...
A Google-search with "mauritsson et al." will give you the references to
several papers on their experiments and conclusions.
It all has to do with interaction between electrons and electromagnetic
fields or, if suitable, photons.
The news about this experiment was written by journalists, they tend to
insist heavily on the more "scoopish" aspects in detriment to physical
aspects.
I would credit the authors, doing a very refined and difficult
experiment, with some sense of what they are doing.
As an aside, I saw a cloud chamber in operation for the first time a"pom" <p...@free.fr> wrote in message

That is an entirely different to "seeing"an actual particle.
As an aside, I saw a cloud chamber in operation for the first time a
few weeks back at the Exploratorium in San Francisco. Very cool, and
very eerie being able to "see" cosmic radiation particles and their
path, many of them passing right through you. I always knew about
this, but "seeing it" for real makes you think WOW!
