Every 18.6 years, our moon reaches its farthest northern and southern point, known as a major lunar standstill. This month, Izzie and Dr Becky are exploring why this might be significant to Stonehenge in the UK and another historical site in the US called Chimney Rock. With special thanks to Dr Heather Sebire, Dr Amanda Chadburn and Dr Erica Ellingson. The southernmost Moonrise at Stonehenge will be livestreamed, allowing viewers to witness this celestial spectacle firsthand. Plus, there'll be events throughout the standstill season which include talks, a pop-up planetarium, stargazing sessions, storytelling, and a new exhibition display at the Stonehenge visitor centre in October.
