Hydrogen Cyanide in HD 163296 (IMAGE) National Radio Astronomy Observatory Caption This composite image of ALMA data from the young star HD 163296 shows hydrogen cyanide emission laid over an artist's impression of a starfield. The MAPS project zoomed in on hydrogen cyanide and other organic and inorganic compounds in planet-forming disks to gain a better understanding of the compositions of young planets and how the compositions link to where planets form in a protoplanetary disk.
