  We start by observing that the light-ray operators featured in the conformal
collider literature are celestial primaries. This allows us to rephrase the
corresponding 4D CFT correlators as probing a conformally soft matter sector of
the 2D celestial CFT (CCFT). To demonstrate the utility of this perspective we
show how the recent $w_{1+\infty}$ symmetry observed in CCFT suggests a natural
extension of the conformal collider operators.
