A novel type of molecule that is longer than some kinds of bacteria has been detected by physicists at the University of Stuttgart in Germany. Using a specially designed microscope, the team observed a binding mechanism between a charged ion and a neutral Rydberg atom – that is, an atom with a single, highly excited valence electron. The extent of the bond length in the new molecule is as wide as a few micrometres, which is at least 1000 times larger than in usual molecules.\
