  Jets of hadrons produced at high-energy colliders provide experimental access
to the dynamics of asymptotically free quarks and gluons and their confinement
into hadrons. In this paper, we show that the high energies of the Large Hadron
Collider (LHC), together with the exceptional resolution of its detectors,
allow multipoint correlation functions of energy flow operators to be directly
measured within jets for the first time. Using Open Data from the CMS
experiment, we show that reformulating jet substructure in terms of these
correlators provides new ways of probing the dynamics of QCD jets, which
enables direct imaging of the confining transition to free hadrons as well as
precision measurements of the scaling properties and interactions of quarks and
gluons. This opens a new era in our understanding of jet substructure and
illustrates the immense unexploited potential of high-quality LHC data sets for
elucidating the dynamics of QCD.
