Why haven't we heard from aliens? SETI scientist says stars can wipe out any possible technosignature we can detect
The reason we haven’t heard from aliens could be remarkably simple: interstellar communication is hard, and turbulent plasma emitted by stars makes it harder. A new study proposes that when listening ...
"We propose it's a natural technological evolution that an advanced civilization could make," Ravi Kopparapu, a NASA planetary scientist who led the research published in the Astrophysical Journal, ...
SETI researchers may have missed alien signals due to a cosmic phenomenon that distorts narrowband radio waves, new research ...
Stellar plasma can smear alien radio signals before they escape their star system, making them harder for astronomers to detect.
In the endless search for technosignatures—signs from some technologically advanced intelligent alien civilization—we’ve done everything from monitoring radio arrays to hypothesizing about whether ...
