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

Most alien-signal searches listen to a narrow part of the radio spectrum, but astronomers are now testing higher frequencies that have barely been explored. A first search using archived ALMA ...

Imagine a super-advanced alien civilization that needs insane amounts of energy way beyond our puny solar panels and wind ...

For decades, science fiction writers have tried their best to prepare us for eventual contact with aliens. Their efforts are dominated by several recurrent tropes. There's the invasion by a warlike ...

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 ...

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 ...

For decades, radio SETI searches have focused on one important question: if another technological civilization is trying to contact us, how would they send that message? For Dr. Zuckerman, the ...

Discover why humanity may be a cosmic anomaly, as we explore traits that set us apart and the implications for alien life. Could our uniqueness explain the silence in the universe?

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 ...

“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 ...

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 ...
