Space is full of electromagnetic radiation like radio signals, but those signals are usually coming from stars or black holes, not planets.

The first unmistakable signal from another intelligence would rank alongside fire and writing in the story of our species, yet a growing group of researchers warns that such a moment might arrive not ...

Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies. Using archived data from the ...

For the first time, astronomers have detected radio signals from a planet beyond our solar system, according to a study available on the preprint server arXiv. The landmark observation offers a new ...

A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space. Turbulent plasma and ...

The Very Large Array is a collection of 27 radio antennas located near Socorro, New Mexico. Each antenna in the array measures 82 feet (25 m) in diameter and weighs about 507,000 pounds (230 metric ...

Astronomers searching for signs of extraterrestrial intelligence may have been missing alien signals in part of the radio spectrum that has not recently been explored. Most radio SETI (Search for ...

Researchers are zeroing in on more deliberate “narrow-band” alien signals, well outside the radio frequencies SETI has focused on for decades. Reading time 3 minutes For over half a century, the ...

Solar winds and coronal mass ejections may scatter narrow signals, making them harder for Earth-based telescopes to detect. The SETI Institute uses radio telescopes to search for signs of intelligent ...
