The Star That Survived Its Companion Going Supernova | Space For Sleep

The Star That Survived Its Companion Going Supernova is the central question of this episode, approached through the evidence, measurements, and competing interpretations behind it. How does A Star in Flight connect to Two Stars, One Tightening Orbit, what The Weight a Star Cannot Hold changes about the investigation, and why the boundary of the question remains difficult to define? A quick note: the visuals in this video are illustrations built to accompany the science, not real photographs or footage of these events.
