This three-dimensional isosurface rendering of the distribution of carbon monoxide emission in the nearby starburst galaxy NGC 253, imaged by the ALMA radio telescope, shows the filaments of a cool molecular wind in position-position-velocity space. Colour corresponds to the intensity of emission from red (faint) to blue-purple (bright). New interferometric observations that reveal the central two kiloparsec region of NGC 253 in unprecedented detail make it possible to measure the mass-outflow rate of the starburst system for the first time. By ejecting around nine solar masses per year (three times the mass converted to stars in the same period), the starburst-driven 'superwind' limits the star formation rate and the number of stars produced in this galaxy.
