Absolutely new type of bond between atoms in a molecule is theoretically predicted to exist in strong magnetic fields generated by white dwarf stars. On Earth effect of magnetic field in atomic bonding is very small, effectively zero, but in the vicinity of  white dwarf stars magnetic forces become comparable in magnitude with electrostatic forces in molecules. Complex calculations were performed for hydrogen molecules. Read more about in September 2012 issue of Chemistry Word or listen to a podcast.
