New Study Suggests Dust, Not Dyson Spheres, Behind Mysterious Infrared Signatures
Astronomers identify seven stars with unusual infrared emissions, but further analysis points to dust-obscured galaxies as the likely cause.
Overview
- Seven M-type stars showed infrared excess, initially raising hopes for Dyson sphere evidence.
- Project Hephaistos used data from Gaia, 2MASS, and WISE to identify these candidates.
- Further research by Tongtian Ren's team linked three stars to radio sources, suggesting extragalactic origins.
- Dust-obscured galaxies are a more plausible explanation for the observed infrared signatures.
- The search for Dyson spheres continues, but current findings favor natural phenomena over alien megastructures.
