Welcome to SpaceTime Series 26, Episode 91 with Stuart Gary. Today, we're exploring the intriguing geology of our celestial neighbors and our home planet. Discover how ancient asteroid impacts may have sparked ongoing volcanism on Venus, keeping its surface youthful despite the absence of plate tectonics. Speaking of plate tectonics, we delve into fresh evidence from a contentious debate regarding Earth's geologic history - new data suggesting our tectonic activity kicked off around 3.2 billion years ago. Next, journey with NASA's Juno spacecraft during its recent close encounter with Jupiter's volcanic moon, Io. As for our own planet, preliminary studies suggest July 2023 could be the hottest month ever recorded. We explore the worrying projections for the Gulf Stream, indicating a potential collapse by 2050 due to climate change. In health news, we question whether healthy individuals over 70 need a daily low-dose aspirin. And finally, for the skeptics out there, we discuss why cascading beer glasses do not constitute evidence of paranormal activity. Join us on this cosmic ride through space and time.
