New Study Suggests Dust, 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.

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.
