It may appear that this recent ASKAP picture shows the array observing the moon, and while the forgeground antenna seems to be looking that way, it is just a trick of perspective. Radio astronomers rarely point their telescopes at the moon, as the moon most often serves to block the view of the universe behind it. There have been some notable exceptions though: observations of the bright radio source 3C273 as it was occulted by the moon in the early 1960s were critical to the discovery of quasars; the ATCA and Murriyang have been pointed towards the moon in a novel attempt to observe brief flashes of radio waves caused by high energy neutrinos interacting with the moon; and ASKAP observations of polarised radio-waves from the moon revealed a “lunar soap bubble”.
