Alma’s image of water-fountain star system W43A, which lies about 7000 light years from Earth in the constellation Aquila, the Eagle. The double star at its centre is much too small to be resolved in this image. However, Alma’s measurements show the stars’ interaction has changed its immediate environment. The two jets ejected from the central stars are seen in blue (approaching us) and red (receding). Dusty clouds entrained by the jets are shown in pink.
