Observational astronomy is one of the oldest natural science. It involves the study of celestial objects and phenomena occurring outside the Earth's atmosphere. Astronomers use a telescope as a receiver to observe starlight at various frequency bands and investigate the universe. The process of collecting starlight is similar to the transmit-receive techniques employed in wireless communication. In this paper, we present the parallels between wireless communication and observational astronomy and extend the scope of wireless communication to astronomical observation. The new paradigm of wireless communication comprises (i) a remote sidereal star (modeled as the signal source), (ii) the Earth's atmospheric turbulence (modeled as time-varying channels), and (iii) a telescope with a camera behind it (modeled as the receiver). We propose fast algorithms to estimate the astronomical time-varying channels, which are highly potential to compensate for blurred astronomical images obtained due to poor astronomical seeing.
