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 ...

A new study published as a preprint on arXiv suggests that advanced extraterrestrial civilizations might not need to surround stars with giant structures to collect energy. Instead, they could extract ...

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.

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 ...
