Scanning tunneling microscopy (STM) is a way to view atoms. It was developed in 1981. It was invented by Gerd Binnig and Heinrich Rohrer at IBM Zürich. They won the Nobel Prize in Physics for inventing it in 1986. For STM, good resolution is 0.1 nm lateral resolution (how accurately it can see features on the surface) and 0.01 nm depth resolution (how accurately it can see the height of bumps on the surface). The STM can be used not only in a vacuum but also in air and various other liquids or gases, and at most common temperatures.
