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.

Beam up to the cosmos as we tackle the challenges of snapping photos at supersonic speeds with the Breakthrough Starshot project. Viano from Florence brings into focus the hurdles of capturing clear images of distant planets when traveling at a third the speed of light. Could the blur of speed and the distortion of space-time leave us with just a glimpse of Proxima Centauri's secrets?Next, we delve into the cosmic dance of celestial bodies. Brady from Florida, with a front-row seat to rocket launches, ponders the possibility of a moon having its own moon. Could a satellite's satellite exist, or are the gravitational tugs within our solar system too much for such a delicate balance? Professor Watson explains the intricate gravitational ballet that determines these cosmic relationships.Then, Scott from Oregon opens a window into the fascinating world of triple star systems with a question about HD 110067. How can stars so far apart still be considered gravitationally bound? Discover the cosmic ties that bind these stellar companions across vast distances.And for a bonus, we tackle an impromptu query from Dean about the Hubble Space Telescope's remarkable ability to maintain steady images while orbiting Earth. The secret lies in the dance of gyroscopes, but how long can this celestial photography session last?From interstellar photography to the gravitational waltz of moons and stars, this episode is packed with insights into the mechanics of our universe.
