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 ...

"Natural astrophysical processes rarely generate extremely narrow spectral features while engineered transmitters often do," writes a team of astronomers including first author Zi ...

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 ...

If advanced aliens lived on a planet within a few hundred to a thousand light years away from Earth, then vast numbers of their signals must already have crossed Earth without being noticed, a new ...

With new technologies come new opportunities. And that is especially true in astronomy—with every new advanced telescope, we have the potential to see (or in some cases, listen) farther and more ...

Astronomers detected radio emission from Beta Pictoris b using South Africa's MeerKAT array. The finding gives scientists a direct way to estimate an exoplanet's magnetic field.

If it were a phone call, we might call it a butt dial: A strong radio signal that set off questions about whether it emanated from an advanced alien race earlier this week is now believed to have come ...
