NASA’s Webb Redefines Dividing Line Between Planets, Stars

NASA's James Webb Space Telescope has provided new insights into the formation of massive celestial bodies, specifically 29 Cygni b, which weighs 15 times that of Jupiter. The findings suggest that this object formed through a process of accretion within a protoplanetary disk, rather than through gas fragmentation, challenging previous assumptions about the formation of such massive planets. This research enhances our understanding of planetary formation and the characteristics that distinguish planets from stars.
