Physics-breaking 'rogue' objects spotted by James Webb telescope are emitting radio signals that scientists can't explain

An image of a young star-forming region filled with wispy blue, grey, green, and red nebulosity that is brightest towards the centre and fainter towards the edges, especially in the top left corner and on the right side. Thousands of stars are seen sprinkled across the field, concentrated towards the centre, and the brightest stars show the eight spikes due to diffraction that are characteristic of Webb images.

In 2023, the James Webb Space Telescope (JWST) helped identify hundreds of free-floating "rogue" planets that don't orbit a parent star. Now, astronomers have found that a pair of these planets may be producing enigmatic, hard-to-interpret radio signals.

The rogue planets spotted by JWST lie in the Orion Nebula, a long-time observational hotspot for astronomers. In total, they number over 500. This discovery bonanza was possible thanks to JWST's ability to pick up infrared radiation emitted by these relatively young planets.
