The cosmic cat and the silver spacecraft
NASA’s Spitzer Space Telescope has a canny set of instruments that can view many things in a light invisible to our eyes: infrared emission. Using its powers of heat surveillance, it images the famous nebula NGC 6334 also known as the Cat’s Paw Nebula.
The concentrations of gas in this image are where stars are born, and they illuminate surrounding dust to present the pink-red features. The green frame of the nebula is where the stellar radiation strikes large molecules, known as polycyclic aromatic hydrocarbons.
