How did the observation of a kilonova change astronomy? How did that one observation kill off alternate models of gravity? What’s in store for the future of gravitational waves?
What are gravitational waves? What makes them? How can we detect them here on Earth, and why is it a big deal? I discuss these questions and more in today’s Ask a Spaceman!
What are the different kinds of asteroids? What are they made of? How can we send missions to capture them, and what will we do once we get one?
