Zöllner became a professor at the University of Leipzig in 1866. His principal works dealt with astronomical photometry. Zöllner designed a photometer for visual determinations of the brightness of celestial bodies. With the aid of a spectroscope, he made some of the first observations of the prominences on the sun. Zöllner also produced studies on the structure of comets and of the solar atmosphere.
