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.
