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.
