Interstellar comets are those that approach the Sun from interstellar space. They were born in an alien planetary system and kicked out, a phenomenon that is evident by the distorted shapes of dusty disks around young stars such as HD 106906. Here I reduced new Hubble data and produced a single image. This animation records what the comet looks like when emphasizing the coma very near the nucleus versus the fainter but more extended comet tail. Comet Borisov will eventually leave our solar system, but until then we should all enjoy the marvelous beauty of our alien comet friend.
