The high harmonic emission that accompanies the recombination of an electron with its parent molecular ion in an intense laser field provides a snapshot of the structure and dynamics of the recombining system. Experiments on CO2 molecules now show how to extract information from the properties of the emitted light about the underlying multi-electron dynamics with sub-Ångström spatial resolution and attosecond temporal resolution
