Researchers propose that tiny technological remnants from extinct alien civilizations could have landed on the moon after ...

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 ...

Somewhere out there, four alien civilizations might already know we exist—and their intentions could be far from friendly. Here's what science really says about it.

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 ...

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 ...
