Radio silence has long puzzled those searching for extraterrestrial intelligence, but the answer might lie much closer to the ...

For four decades, many SETI experiments have focused on finding sharp spikes in frequency but the new study says signals may not stay narrow as they travel away from their home system.

We may be missing alien radio signals because they have become smeared beyond the narrowband detectors that SETI utilizes, a new study suggests.

A new study by the SETI Institute suggests that the alien signals might be right here, surrounding us all of the time, and we're just unable to pick them out.

What if there were aliens on some distant planet and what if they tried to contact us, but we were not able to pick up the message? That is the question that has been raised by a group of scientists.

As binary neutron stars spiral around each other to merge, their gravitational tidal forces distort each other's shape and structure, potentially revealing clues as to what lies within them.

SETI researchers may have missed alien signals due to a cosmic phenomenon that distorts narrowband radio waves, new research ...
