The Very First Image of a Hydrogen Bond "Using a technique called high-resolution atomic force microscopy (AFM), researchers in China have visualized the molecular structure of a hydrogen bond."
Bonus science image: We have seen clouds on a giant planet beyond our solar system. "By observing this planet with Spitzer and Kepler for more than three years, we were able to produce a very low-resolution 'map' of this giant, gaseous planet," said Brice-Olivier Demory of Massachusetts Institute of Technology in Cambridge. Demory is lead author of a paper accepted for publication in the Astrophysical Journal Letters. "We wouldn't expect to see oceans or continents on this type of world, but we detected a clear, reflective signature that we interpreted as clouds."
