S27E68: Unveiling Venus: New Volcanic Activity Discovered
Join us for SpaceTime Series 27 Episode 68, where we explore the latest cosmic discoveries and technological advancements shaping our understanding of the universe.First, we uncover new evidence suggesting that Venus is volcanically active. By analysing data from NASA's Magellan radar, scientists have identified two volcanoes on Venus that erupted in the early 1990s. This discovery adds to the growing body of evidence that Venus may be far more volcanically active than previously thought.Next, we discuss the discovery of a new kind of volcanic eruption on Earth. Researchers have identified a unique eruption mechanism at Hawaii's Kilauea volcano, describing it as a "stomp rocket" eruption driven by sudden pressure increases as the ground collapses.Finally, we look forward to the maiden flight of the European Space Agency's new Ariane 6 rocket, now slated for next month. This launch marks a significant milestone in Europe's space exploration capabilities.00:00 This is spacetime series 27, episode 68 for broadcast on 5 June 202400:45 Two volcanoes on Venus appear to have erupted in the early 1990s05:40 Venus is often considered to be earths sister planet with runaway greenhouse effect09:47 Scientists say Kilauea volcano erupted like a stomp rocket in 201814:05 The maiden flight of the European Space Agency's new Ariane six rocket now likely19:19 The upper and main stages of the Ariane six flight model have arrived22:03 New study says vaccines for bird flu are best defence if virus spreads between humans24:03 Study finds popular teens sleep 27 minutes less per night than their peers25:57 There are growing concerns about inaccurate information coming out of artificial intelligence programmes26:41 Google's AI overviews are giving very strange information based on Reddit posts27:45 Sam Altman has rushed to form a new AI safety team31:03 Spacetime is available every Monday, Wednesday and Friday Follow our cosmic conversations on X @stuartgary, Instagram, YouTube, and Facebook.
