After another year with Swann, now in Chicago, and a year at various labs in the Netherlands and Germany and two months at Niels Bohr's lab in Copenhagen, he became a postdoc at Caltech. Here he wrote a famous paper, An Application of the Quantum Theory to the Luminosity of Diffuse Nebulae, which for the first time provided a quantitative method (the "Zanstra method") for understanding the luminosity of nebulas and comets.

After teaching briefly at the University of Washington he went to London and eventually to the University of Amsterdam. World War II left him stranded in South Africa, and he therefore took up a teaching position in Durban, but returned to Europe after the war. In 1949 he became member of the Royal Netherlands Academy of Arts and Sciences.He won the Gold Medal of the Royal Astronomical Society in 1961.

The lunar crater Zanstra is named after him, as is Asteroid 2945 Zanstra.
