What are the "JuMBO" objects found in the Orion Nebula?

Scientists at the European Space Agency have used the James Webb Space Telescope to reveal the presence of pairs of planet-like objects in the Orion Nebula that have never been detected before.

Referred to as "JuMBOs" - free-floating objects the size of Jupiter - the discovery has the potential to upend our understanding of how stars and planets are formed.

Joining Jonathan to discuss this is Mark McCaughrean, ESA Senior Advisor for Science & Exploration.
