The search for extraterrestrial intelligence (ETI) has long been a topic of fascination. However, a new study available on the arXiv preprint server introduces a compelling idea about how we might ...

Looking ahead: Existing radio surveys may contain signals that were never recognized as potential technosignatures. New ...

Black holes can release enormous energy through hot disks, surrounding plasma and powerful jets, enough to support a ...

Is anybody out there? Probably. Most stars have planets; we've discovered more than 6,000 exoplanets thus far, and the most basic statistics point toward the existence of countless potentially ...

The Fermi paradox asks why we haven’t found aliens yet. Scientists say the answer may lie in timing, technology, and the vast scale of space.

We’ve likely had at least one close encounter of the 3I kind before. Harvard scientist Avi Loeb claims that not only does 3I/ATLAS potentially have alien origins, but that this wouldn’t be the first ...

In 1995, a pair of scientists discovered a planet outside our solar system orbiting a solar-type star. Since that finding—which won the scientists a portion of the 2019 Nobel Prize in ...

“There is a silence in the night sky that has bothered me for as long as I can remember.” That line, attributed to Richard Feynman, lands because it gets at a simple, stubborn feeling. The sky looks ...

In 1961, Dr Frank Drake proposed a probabilistic, though highly speculative, equation to determine the number of intelligent ...

They’re hole-ar powered. If super-advanced alien civilizations exist, they would surely require insane amounts of energy to ...

Hollywood makes initiating alien contact seem much easier than it has proven to be. In E.T. the Extraterrestrial, E.T. got stranded on earth when his alien compadres abandoned their botany mission. In ...

For decades, SETI researchers have focused on finding narrow-band radio signals that might stand out from the natural universe. But what if an advanced civilization that wanted to communicate would ...
