14 APR 2024 · In this episode of Space Nuts Q&A, Andrew and Fred answer questions about supernovae, 3D printed telescopes, the Voyager space probe missions, and the possibility of using particle collision in space. They discuss how supernovae explosions do not blow away the gravitational field and how neutron stars develop as a result. They also provide insights into 3D printed telescopes and suggest that beginners may find it easier to start with an off-the-shelf telescope. They talk about the trajectory and potential fate of the Voyager spacecraft and discuss the challenges of building particle colliders in space. Overall, they provide informative and engaging answers to the audience's questions. Takeaways   Supernovae explosions do not blow away the gravitational field because gravity is associated with mass. The explosion only affects the outer envelope of the star, while the core collapses to become a neutron star. 3D printed telescopes can be a good option for beginners, but it may be easier to start with an off-the-shelf telescope. 3D printed telescopes require more components and may involve more fiddling around. The Voyager spacecraft will continue on their current trajectories and are not expected to pass near any star systems within human lifetimes. However, if they were near enough to Earth, they could be detectable by extraterrestrial intelligence. Building particle colliders in space is challenging due to the need for precise guidance and the high velocities of the particles. It may be more cost-effective and realistic to continue building particle colliders on Earth. The fate of the Voyager spacecraft is uncertain, but they could potentially be captured into orbit around another star or collide with other objects. They will likely outlast our species and continue on their trajectories away from the solar system.

28 MAR 2024 ·   In this episode of Space Nuts, Andrew Dunkley and Professor Fred Watson discuss two scientific discoveries. The first is the synthesis of new isotopes in a lab using a laser, replicating a process that occurs during colliding neutron stars. The scientists at the Facility for Rare Earth Isotope Beams (FRIB) have created isotopes that have never existed on Earth before, shedding light on the processes that occur during neutron star collisions. The second discovery is the brightest quasar ever found, located at a great distance in the universe and with a luminosity 500 trillion times that of the sun. This quasar is believed to be extinct in the present universe, but its discovery provides valuable insights into the early universe. In this episode of Space Nuts Q&A, Andrew and Fred discuss various topics including the possibility of microorganisms on Titan, the feasibility of terraforming Venus, the formation of protostars, and the enjoyment of science fiction. They also answer a question about seeing the moon during the day and its visibility in different parts of the world. Takeaways   Scientists have successfully synthesized new isotopes in a lab using a laser, replicating a process that occurs during colliding neutron stars. This discovery sheds light on the processes that occur during neutron star collisions and the creation of heavy elements like gold and silver. The Facility for Rare Earth Isotope Beams (FRIB) at Michigan State University has created isotopes that have never existed on Earth before, marking a significant achievement in nuclear physics. A quasar with a luminosity 500 trillion times that of the sun has been discovered, making it the brightest object in the universe. This quasar is believed to be extinct in the present universe, but its discovery provides valuable insights into the early universe. Both discoveries highlight the importance of scientific research and exploration in understanding the fundamental processes of the universe and the origins of elements. Recent data suggests that Titan may not be as life-worthy as previously thought, but there is still a possibility of microorganisms that use ethane and methane as their working fluid. Building a huge megastructure at Venus's L1 point to block all sunlight and cool down the planet would not be feasible due to gravitational forces and instability. The visibility of the moon during the day is possible because the moon is often above the horizon at the same time as the sun, and its phases differ from those of the sun. The enjoyment of science fiction can vary, and some people prefer stories that are scientifically accurate, while others enjoy stories that stretch the boundaries of possibility. Favorite sci-fi works mentioned include The Martian, Dune, Isaac Asimov's Nemesis, Hitchhiker's Guide to the Galaxy, and Arrival.   Chapters   00:00 Recreating Heavy Elements and Brightest Quasar 00:13 Synthesizing Isotopes and Understanding Neutron Star Collisions 03:03 The Process of Synthesizing Isotopes 06:06 The Facility for Rare Earth Isotope Beams (FRIB) 09:19 The Journey to Understand Nuclear Processes 10:47 The Meaning of Synthesizing Isotopes 18:38 Discovering the Brightest Quasar 21:48 The Enormity of the Brightest Quasar 23:21 Quasars and Extinction 24:19 The Quasar in Today's Universe 25:58 The Brightest Quasar in the Universe 30:23 Terraforming and Cooling Venus 34:12 The Formation of Protoplanetary Disks 45:25 The Enjoyment of Science Fiction 51:43 Seeing the Moon During the Day

21 MAR 2024 · Dive into a cosmic quandary and a celestial debate in this latest installment of Space Nuts! Host Andrew Dunkley and the insightful Professor Fred Watson explore the diminishing hopes for life on Saturn's moon, Titan. With new research suggesting the slim chances of a prebiotic mix in Titan's sub-ice ocean, our hosts examine the implications for other icy moons in our solar system. Could the once promising Titan be less hospitable to life than we thought? Then, we shift gears to the bureaucratic realm as the United Nations finally agrees to discuss the impacts of satellite constellations on astronomy. With over 8,000 satellites already orbiting Earth and many more planned, the astronomical community faces challenges in keeping the night sky dark and the radio spectrum quiet. Will the UN's slow-moving wheels make a difference in this rapidly advancing industry? Listeners also get a chance to ponder the existence of the elusive Planet Nine and step into the shoes of an interstellar explorer as Andrew and Fred answer a what-if question about visiting exoplanets. Plus, we revisit a listener's innovative idea for a solar pergola designed to mitigate climate change - a concept that aligns with recent scientific proposals.
