Extraterrestrial Cycloids – Why Are They on Europa?

From Minute Physics. Thanks to the James Webb Space Telescope (JWST) and Space Telescope Science Institute for supporting this video. This video is about the cycloid curves on Jupiter’s moon Europa – they’re ridges or valleys in the icy surface that formed due to some sort of geological or tectonic-esque phenomenon. The answer involves ping…

The Brown Dwarf Debate

From Minute Physics. 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…
