CosmoView Episode 37: Largest Collection of Free-Floating Planets Found in the Milky Way

Using observations and archival data from several of NSF NOIRLab’s observatories, together with observations from telescopes around the world and in orbit, astronomers have discovered at least 70 new free-floating planets — planets that wander through space without a parent star — in a nearby region of the Milky Way. This is the largest sample of such planets found in a single group and it nearly doubles the number known over the entire sky.
