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.
Another possibility is that they were made around stars and were then kicked out into interstellar space through various interactions.
"The ejection hypothesis is the favoured one at the moment," said Prof Mark McCaughrean.
