Join Andrew Dunkley and Professor Fred Watson in this captivating episode of Space Nuts as they explore some of the most intriguing phenomena in space science.First up, zebrafish are making waves in orbit! These tiny aquanauts are part of a Chinese space mission on the Tiangong space station. Discover why zebrafish are ideal candidates for space research and what their genetic similarities to humans could reveal about the effects of zero gravity on biological organisms.Next, delve into the mystery of the cold spot in space, a peculiar anomaly within the cosmic microwave background radiation. Fred explains the significance of this cold spot, its potential causes, and why it challenges our understanding of the universe's isotropy. Could a giant cosmic void be the culprit, or is there another explanation lurking in the cosmos?Additionally, the duo discusses the exciting progress of the Vera C. Rubin Observatory, featuring the world's largest digital camera, which promises to revolutionise our view of the night sky. Learn about its remarkable capabilities and the potential discoveries it could unveil, including the elusive Planet Nine.
