No Alien Signals Detected in ALMA’s High-Frequency Search, but SETI Expands into Millimeter Wavelengths via Galactic-Beam Modeling
To the point
Led by Louisa Mason, the study repurposes archived ALMA data in millimeter and submillimeter bands beyond the water hole to search for technosignatures, finds no alien signals, and shows that galactic models can reveal over 6.18 million stars across 1,229 pointings within telescope beams to guide future SETI surveys and transmitter-power constraints.
