Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have obtained a vivid close-up view of material streaming away from a newborn star. By looking at the glow coming from carbon monoxide molecules in an object called Herbig-Haro 46/47 they have discovered that its jets are even more energetic than previously thought. In these observations from ALMA the colours shown represent the motions of the material: the blue parts at the left are a jet approaching the Earth (blueshifted) and the larger jet on the right is receding (redshifted).
