Abstract

A high-velocity outflow of molecular gas from a starburst galaxy has been observed to extend about ten kiloparsecs; its velocity is consistent with the momentum flux from stellar radiation pressure, showing that bursts of star formation can eject large amounts of cold gas from the central regions of galaxies, curtailing star formation.
