A new study suggests alien life may be easier to detect through clusters of similar planets rather than single biosignatures.

Here’s what you’ll learn when you read this story: The Search for Extraterrestrial Intelligence (SETI) focuses on finding technosignatures—potential signs of alien technology. If we look carefully, we might have a chance at detecting their ...

We have no idea what kind of life may exist on other planets, so it’s hard to know what to look for. Proxima Kósmos imagines a very different kind of solar system that could harbor life-forms we haven’t yet thought of.

Aristotle believed the planets revolved around Earth and God could not have created other worlds. Today, scientists scour the surface of Mars for ‘biosignatures’ of microbial life.
