Embark on a celestial journey with Andrew Dunkley and Professor
Fred Watson in this episode of Space Nuts, where they explore a
variety of space phenomena that are as intriguing as they are
mysterious. Firstly, they discuss Blue Origin's return to the stars
with NS-25, a mission that marked a triumphant comeback after
technical setbacks. The flight not only signifies Blue Origin's
resilience but also the inspirational story of Ed Dwight, the first
African-American astronaut candidate, who at 90 years old, set a
record as the oldest person to reach space.Next, the conversation
lightens with the discovery of a planet with the consistency of
fairy floss, also known as cotton candy or candy floss. WASP-193b,
a gas giant that defies the norms of density and composition,
leaves astronomers scratching their heads. How does a planet become
so 'fluffy'? What could it possibly be made of? These are the
questions that Andrew and Fred ponder as they delve into the
mysteries of planet formation.Lastly, the duo discusses the
gravitational wave background in the universe, likening it to the
cosmic microwave background radiation. They explore how pulsar
timing arrays are providing new insights into the 'hiss' of
gravitational waves created by countless cosmic events, offering a
deeper understanding of the universe's dynamic fabric.From
record-breaking astronauts to cotton candy planets and the cosmic
symphony of gravitational waves, this episode of Space Nuts is
packed with astronomical wonders that will leave you in awe. Tune
in and let your curiosity soar to the farthest reaches of
space.00:00:00 This is Space Nuts, where we talk astronomy and
