In this episode of SpaceTime, we explore the intriguing phenomena of coronal holes on the Sun and their significant impact on space weather. A new study published in Scientific Reports reveals how these magnetic windows are launching supersonic solar wind streams into the heliosphere, providing crucial insights for future solar monitoring missions like ESA's Vigil. We discuss the dangers posed by solar storms to Earth's infrastructure and how advanced forecasting can mitigate these risks.

Watery Past of Mars

Next, we uncover exciting findings from NASA's Perseverance rover, which suggest that Mars once had widespread water, as indicated by the presence of calcium sulfate minerals. Utilizing innovative X-ray backscattered diffraction techniques, scientists are piecing together the planet's geological history and its potential for past life.

NASA's Lucy Mission Success

Finally, we celebrate the successful flyby of the main belt asteroid Donaldjohanson by NASA's Lucy spacecraft. Captured images reveal its unique potato-like shape and complex geology, shedding light on the building blocks of our solar system. With future encounters on the horizon, Lucy aims to enhance our understanding of planetary formation.

Space Nuts Episode 516: Angular Momentum, Cosmic Inflation, and the Infinite Universe

In this thought-provoking episode of Space Nuts, host Heidi Campo steps in for Andrew Dunkley, joined by the ever-knowledgeable Professor Fred Watson. Together, they tackle an array of fascinating listener questions that delve into the complexities of angular momentum, the nature of cosmic inflation, and the mysteries surrounding the universe's finiteness or infiniteness.

Episode Highlights:

- Angular Momentum Explained: Heidi and Fred kick off the episode by addressing a question from Buddy about angular momentum. They discuss how angular momentum affects spinning objects, the implications of expansion, and the intriguing concept of a potentially spinning universe.

- Time Dilation and Cosmic Inflation: Scott from Sydney poses a compelling question regarding time dilation during the universe's hyperinflation period. Fred elaborates on how time behaves under extreme gravitational conditions and the significance of inflation in explaining the universe's homogeneity.

- Is the Universe Finite or Infinite? The episode features a delightful audio question from young Enrique and his father Philip, exploring whether the universe is finite or infinite. Fred explains the concept of cosmic horizons and the challenges faced in determining the universe's boundaries.

- Temperature Control on the ISS: Kevin from Melbourne asks about the temperature inside the International Space Station (ISS) and how it varies with sunlight exposure. Heidi and Fred discuss the engineering marvels that maintain a livable environment for astronauts, including the challenges of thermal regulation in space.
