In a distant stellar system, the JWST sees the end of planet formation
   Every time a star forms, it represents an explosion of possibilities. Not for the star itself; its fate is governed by its mass. The possibilities it signifies are in the planets that form around it. Will some be rocky Will they be in the habitable zone Will there be life on any of the planets...
