INBOX ASTRONOMY NASA's Webb Redefines Dividing Line Between Planets, Stars Release date: Tuesday, April 14, 2026 10:00:00 AM Eastern Daylight Time Composition and orbit of super-chonky 29 Cygni b point to accretion within a protoplanetary disk. Where is the dividing line between stars and the most massive planets? Scientists think it may depend on how they formed. Was it from a bottom-up approach, gradually growing larger over time, or a top-down approach in which a large collection of gas and dust fragment ...Continue Reading
