 act: Gluons constitute the bulk of the mass of the visible universe and pl
 ay a major role in determining the fundamental properties of protons\, neu
 trons and other hadrons\, but their arrangement within hadrons is relative
 ly poorly known. The one-dimensional structural properties of hadrons are 
 partly encoded in parton distribution functions (PDFs)\, which capture the
 ir longitudinal momentum structure. Our knowledge of the gluon PDF of the 
 nucleon has been significantly improved by the wealth of data from the Lar
 ge Hadron Collider\, but many aspects of gluon structure are still unclear
 . I will introduce the techniques used to determine hadron structure from 
 lattice quantum chromodynamics (QCD)\, the numerical solution of QCD on a 
 Euclidean spacetime lattice\, and then discuss the HadStruc collaboration'
 s recent attempts to understand the gluon structure of hadrons\, outlining
  some of the challenges involved in these first-principles calculations.
