Just like the back of a spoon reflects visible light, appearing to curve straight lines, so too does the Moon reflect the otherwise straight line of our Milky Way galaxy into a circle when at the right angle. November 2018’s “Monthly Media” is a series of simulated images from Dr Ben McKinley’s recent paper detailing how we can use the Moon to better detect the Epoch of Reionisation during the very early Universe.

As time passes, the position of the reflected galaxy changes on the Moon.
