Thanks to NASA's James Webb Space Telescope (JWST) project and the Space Telescope Science Institute for supporting this video.

This video is about the line between Brown dwarfs and gas giant planets (aka super Jupiter's): does it exist? Is it the deuterium-burning threshold? Behavior? Metallicity? Formation? Or is there no meaningful scientific distinction, and are brown dwarfs and giant planets really all on a spectrum with no clear line between them?
