Results of a recent supercomputer analysis of lattice QCD with dynamical fermions are presented. Gluon fields inside mesons and baryons with static (infinitely heavy) quarks are described. The breaking, due to the creation of a quark-antiquark pair from a vacuum, of the string that couples quarks into hadrons is discussed. The finite temperature QCD phase transition is considered. The results obtained show that the QCD vacuum behaves as a dual superconductor and that color confinement is due to the formation of a dual analog of the Abrikosov string.
