Free Floating Binary Planets Can't Last Long

The JWST continues to live up to its promise by revealing things hidden from other telescopes. One of its lesser-known observations concerns Free-Floating Planets (FFP). FFPs have no gravitational tether to any star and are difficult to detect because they emit so little light. When the JWST detected 42 of a particular type of FFP in the Orion Nebula Cluster, it gave astronomers an opportunity to study them more closely.
