NASA’s James Webb Space Telescope (JWST) rules out two new Dyson sphere candidates after a search for infrared technosignatures consistent with the hypothetical megastructure. The targets are two stellar candidates identified for follow-up based on earlier indications that a Dyson sphere might be producing detectable excess radiation.
Multiple sources report that the latest analysis finds no evidence supporting the Dyson sphere interpretation. Phys.org describes the work as part of a Swedish-led effort to test stars for technosignatures, while Universe Today similarly reports that the search returns empty results for these two candidates. The overall context is that scientists use JWST’s sensitivity to infrared emission, looking for characteristic patterns that could differ from what standard stellar and circumstellar processes produce.
While the specific details of the candidates and observational results are presented in each outlet’s write-up, both accounts converge on the same outcome: the two stars are no longer considered viable Dyson sphere explanations based on JWST data, leaving the broader technosignature hunt ongoing and subject to further candidate selection and future observations.
