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

Scientists have spent 60 years searching for extraterrestrial signals, yet calculations suggest humanity has explored only a ...

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 ...

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.

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 ...

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 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 ...

“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 ...
