Strong laser fields enable taking snapshots of a molecule using its own electrons. The electrons are ionized from the molecule, accelerated by the laser field and driven back to recombine with their parent ion, emitting a flash of light which encodes the molecular structure. We have performed an experiment in which two consecutive sets of electrons probe the same molecule, providing two snapshots separated by a few hundreds attoseconds. Comparing these two snapshots reveals the dynamics of the molecule in the strong laser field.
