Jupiter-sized “planets” free-floating in space, unconnected to any star, have been spotted by the James Webb Space Telescope (JWST).
What’s intriguing about the discovery is that these objects appear to be moving in pairs. Astronomers are currently struggling to explain them.
The telescope observed about 40 pairs in a fabulously detailed new survey of the famous Orion Nebula.
They’ve been nicknamed Jupiter Mass Binary Objects, or “JuMBOs” for short.

One possibility is that these objects grew out of regions in the nebula where the density of material was insufficient to make fully fledged stars.
"Gas physics suggests you shouldn’t be able to make objects with the mass of Jupiter on their own, and we know single planets can get kicked out from star systems.
It’s one for the theoreticians," the European Space Agency’s (Esa) senior science adviser told BBC News.
Along with the quartet of bright suns at its centre called the Trapezium, this region of space is visible to the naked eye as a smudge on the sky.
Look at the longer wavelength version to examine the sculpted green clouds of gas that contain polycyclic aromatic hydrocarbons.
Initial papers describing the survey and the JuMBO discovery will be posted on the arXiv pre-print server on Tuesday.

But how do you kick out pairs of these things together? Right now, we don’t have an answer.
I have an hypothesis: space snooker
