Cool Stars May Have Different Prebiotic Chemical Mix

Cool Stars May Have Different Prebiotic Chemical Mix NASA's Spitzer Space Telescope detected a prebiotic, or potentially life-forming, molecule called hydrogen cyanide (HCN) in the planet-forming disks around yellow stars like our sun, but not in the disks around cooler, reddish stars.The observations are plotted in this graph, called a spectrum, in which light from the gas in the disks around
