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.

The bottom line is Dave's right to question this, because we can't guarantee what the universe is going to do. We don't have any sort of control over that. All we can do is observe what it's doing now, and through the magic of the fact that we can look back in time, we get a good idea of what it's done in the past. - Fred Watson Glass Z 12 High-Redshift Galaxy Glass Z 12 is a high-redshift galaxy, noted for its advanced state of maturity shortly after the Big Bang. Its study, largely facilitated by the GrISM lens Amplified Survey from Space (GLASS) using the James Webb Space Telescope, sheds light on the early universe's formation and evolution. Despite the advanced observational technology, the nature of such galaxies holds persisting enigmas, stimulating ongoing research and debates in the astronomical community.
