New research suggests that alien radio signals may be transformed by plasma from their home stars — and scientists on Earth could thus be overlooking prime evidence of alien intelligence.

The “Wow!” signal is one of our best pieces of evidence for aliens, but researchers are building a compelling case for a more ...

A comet from another star system does not arrive every year. That is part of what made 3I/ATLAS so compelling when it appeared in July 2025.

A study suggests that stellar plasma may distort alien signals, complicating SETI's search for extraterrestrial life by pushing signals below detection thresholds.
