Webb spots the 'smoke' from crashing exocomets around a nearby star The James Webb Space Telescope (JWST) was involved in yet another first discovery recently available in pre-print form on arXiv from Cicero Lu at the Gemini Observatory and his co-authors. This time, humanity's most advanced space telescope found UV-fluorescent carbon monoxide in a protoplanetary debris disk for the first time ever. It also discovered some features of that disk that have considerable implications for planetary formation theory.
