Abstract
Modern optics focuses on photonics and quantum optics, studying individual photons, and statistics of photon streams. Those can be complex and carry information beyond that recorded by imaging, spectroscopy, polarimetry, or interferometry. Since [almost] all astronomy is based upon the interpretation of subtleties in the light from astronomical sources, quantum optics has the potential of becoming another information channel from the Universe. The observability of quantum statistics increases rapidly with the telescope size, making photonic astronomy very timely in an era of very large telescopes.
