Join Andrew Dunkley and Professor Fred Watson for another exciting episode of Space Nuts. This week, we're diving into some stellar discoveries and cosmic conundrums that will leave you starstruck! First up, we explore an Earth-like planet discovered by Australian and Scottish scientists. This exoplanet, located 40 light-years away, sits in the Goldilocks zone of a red dwarf star, making it a tantalising candidate for hosting liquid water. Could this be our new home away from home?Next, we tackle the growing concern of satellite noise and its potential threat to the Square Kilometre Array (SKA). Fred shares insights from his visit to the UN in Vienna, discussing how astronomers and industry are working together to mitigate this issue. Finally, we delve into the search for Dyson spheres or megastructures in space. An op-ed piece argues why these colossal constructs probably don't exist, but could there still be a chance of finding one? Tune in for these fascinating topics and more on Space Nuts!

Join Andrew Dunkley and Professor Fred Watson for another enlightening episode of Space Nuts Q&A. This week, we tackle a variety of listener questions that delve into the fascinating intricacies of space science and astronomy.
First, we revisit a question from Alan about the detectability of light at one candle power of an LED in space. Fred breaks down the calculations and assumptions, providing insights into how far such a light source would be visible, even with the Hubble Telescope.
Next, Nate from Queensland asks about bolometric luminosity and its implications for predicting changes in stars, such as supernovae. Fred explains the concept of bolometric measurements, the use of bolometers, and whether there's a standard way to predict changes in a star's luminosity.
David from Melbourne brings up Hawking radiation and its potential connection to dark matter and dark energy. Fred clarifies the nature of Hawking radiation and discusses recent research linking black holes to dark energy, albeit without involving Hawking radiation.
Martin from Maryland poses a question about the hazards of near-light-speed travel for spacecraft and their biospheres. Fred explores the potential dangers, including nuclear interactions and radiation, that could arise from such high-speed travel.
Finally, Ryan from Delaware inquires about the feasibility of refuelling or repairing the James Webb Space Telescope. Fred explains the challenges due to its location at the L2 point and the economic considerations that make such missions unlikely.
