A Major Lunar Standstill (MLS) – an astrological phenomenon which takes place once every 18.6 years, when moonrise and moonset are furthest apart along the horizon – is due to occur in 2024 and 25. It is believed that at least one MLS was marked during the early phase of Stonehenge and some academics believe there may be a connection between this and the placement of the Station Stones at Stonehenge.

Joining us to discuss the theory and the project putting it to the test are English Heritage senior properties historian Dr Jennifer Wexler, emeritus professor of archaeoastronomy at the University of Leicester Clive Ruggles and senior lecturer in archaeological modelling at Bournemouth University Dr Fabio Silva.
