Despite its size, its heavy-element composition and orbital alignment reveal a planetary origin. The findings confirm that it formed through accretion in a protoplanetary disk, rather than as a star via gas cloud collapse. This challenges existing classifications and helps define the upper limits of planet formation. The study offers new insight into how the largest worlds emerge—blurring the boundary between planets and stars and reshaping our understanding of cosmic evolution. Thank you for listening to Bedtime Astronomy — your guide to the cosmos. New episodes on space exploration, NASA missions & the latest astronomy breakthroughs.","meta_description":"Using the James Webb Space Telescope, scientists have analyzed 29 Cygni b, a massive object with fifteen times the mass of Jupiter.
