UArizona Regents Professor Lucy Ziurys and her collaborators took advantage of the radio antennas at the Atacama Large Millimeter Array, or ALMA, to detect the very faint emissions of organic molecules in various planetary nebulae, remnants of dying stars. ALMA sits atop a plateau in Chile's Atacama Desert, 16,500 feet above sea level, where the atmosphere is undisturbed and allows for clear observing. (Image: C. Padilla, NRAO / AUI / NSF)
