Spacetime With Stuart Gary

In this episode of SpaceTime, we unlock the secrets of the Moon's far side, explore the Sun's helicity barrier, and discuss the European Space Agency's advancements in orbital launch vehicles.Extended Volcanism on the Moon's Far SideRecent findings reveal that the Moon's far side has experienced extended volcanism for at least 1.4 billion years, with two significant volcanic phases occurring around 4.2 and 2.8 billion years ago. This research, stemming from samples collected by China's Chang' E6 mission, provides insights into the Moon's geological history and the asymmetry between its near and far sides. The study highlights the role of colossal impacts in shaping the Moon's interior and suggests uneven distribution of volatile elements.Discovery of the Sun's Helicity BarrierA groundbreaking study has identified a region of the Sun known as the helicity barrier, which plays a crucial role in heating and accelerating the solar wind. Observations from NASA's Parker Solar Probe have confirmed the existence of t
