Live Q&A: Hubble Detects Farthest Star Ever Seen

The video features a discussion on Hubble's discovery of the farthest individual star, Arrendel, and the role of gravitational lensing in this discovery. Experts explain the significance of studying early stars and how the James Webb Space Telescope will further enhance these observations. The complementary roles of Hubble and Webb are highlighted, and audience questions are addressed.
