Discovering Exomoons, Gravitational Lenses for JWST and Hubble, Jupiter's Core Mass | Q&A 233
How can neutrinos arrive faster than light? How did OSIRIS-REx get samples of an asteroid? Can we extract energy from gravitational waves? When will we be able to discover our first exomoon of an exoplanet? How can we measure the mass of Jupiter's core? Answering all these questions and more in this week's Q&A show.

I have 3 questions: 1) In this episode, you answered a question about exomoons. Can our technology differentiate between an exoplanet with a moon and a larger planet without one? 2) Is there a limit to the number of objects that can be in a planetary system, either orbiting a star or rogue? I, personally, think it would be great if we could find a rogue planetary system with 3, 4, or 5 objects 3) When an object is said to be, for example, 10 million light years away, is that the distance that the light traveled to us, or is that how far away the object is currently accounting for the travel lag?
Is this the best place to post a question for QA
I don't know if I missed it but I have a question: when scientists detect planets around a star by orbital perturbations, or Transit-timing variation, is there a minimum mass for detection? which makes me wonder: Could you, theoretically, detect a civilisation's space station around a star with this method?
