Scientists say coldest 'stars' in Milky Way could actually be giant alien technology harvesting energy th

A new study suggests the galaxy’s coldest celestial objects, previously classified as stars, could instead be massive artificial structures—such as Dyson spheres—built by advanced extraterrestrial civilizations to capture stellar energy. Researchers highlight four key observational tests, including infrared and X-ray signatures, to distinguish between natural stars and potential megastructures using data from the James Webb Space Telescope, Vera C. Rubin Observatory, and NASA’s Nancy Grace Roman Space Telescope.

Coverage from *Tech Times*, *ScienceDaily*, and *The Times of India* emphasizes the theoretical framework linking unusually cold objects to energy-harvesting technology, citing anomalies in their thermal emissions. The Business Standard and *businesstimes-bd.com* frame the study as a shift in SETI (Search for Extraterrestrial Intelligence) strategies, though no direct evidence of alien origin has been confirmed. Next steps involve cross-referencing telescope data against the proposed four-test checklist.

If anomalies persist, follow-up observations could reclassify these objects—or rule out the megastructure hypothesis entirely.
