Pohl created his map using a kinetic model of the galaxy's gas flow, which was developed by Peter Engelmeier of the University of Zurich and Nicolai Bissantz of Ruhr University in Bochum, Germany, based on infrared data collected by a NASA satellite. Unlike visible light, infrared light penetrates dust clouds, so it provided Engelmeier and Bissantz with more precise measurements, in turn allowing Pohl to produce a more accurate, if not perfect, map. "Our method works over much...
