Yes, this JWST is a strange object. It has arrived at and docked with the L2 point, where it orbits both the Earth and the Sun at the same time. From L2 the Sun lights up the whole Universe incl. Earth with its Moon, so that the JWST can see all without being disturbed by an atmosphere. I can only see the Universe by looking out of my window where a visible Universe is there in the sky on a clear night all the time. However, before JWST can see anything at L2, it has to be adjusted. It will take some extra months.
But nobody is perfect. I cannot see the back of the Moon from my window, only the face of the Moon, as it orbits Earth. I wonder if JWST can see the back of the Moon from L2? Any ideas?
