Subject: How does an electron look like when it is observed through a microscope?

I want to know whether an electron looks like a vague cloud when observed 
through the most poweful microscope or as a clear particle with definite 
location and size. I know that electron's position cannot be accurately 
measured because of uncertainity principle. But I want to know whether it is 
possible to atleast make some measurement inspite of it's uncertainity or will 
we only get to see a vague cloud in which electron can be anywhere and cannot 
be measured at all? Kindly clarify my doubt as soon as possible. I know very 
little about physics and I have no idea if what I ask even makes sense. But I 
like to have some idea on that. Thanks in advance.
