An awe-inspiring and comprehensive exploration into the grand scientific quest for extraterrestrial intelligence, examining ...

Astrobiology—the study of life in the universe, from how it began and evolved to how it might take shape elsewhere—is the ...

Imagine a super-advanced alien civilization that needs insane amounts of energy way beyond our puny solar panels and wind turbines to power their mega-cities, AI overlords, or whatever interstellar ...

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 ...

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 ...

Despite the alien hubbub and hoopla of the past few years, we still don’t know for certain if we are alone in the universe. We haven’t even found the tiniest scrap of evidence to suggest that there ...

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 ...

In 1950, famed astrophysicist Enrico Fermi posed a profound question during a casual lunch with colleagues: Where is everybody? In other words, if there’s an extremely high probability that advanced ...

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 ...

For as long as we’ve been exploring space, the search for alien intelligence has followed a familiar script. We point antennas at the sky. We listen for radio signals. We scan for massive structures ...
