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 ...

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

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.

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.

A new study proposes detecting life in space by spotting patterns across many planets instead of focusing on one at a time. If life spreads and changes planetary environments, it could leave behind statistical clues linking planets together.

Planets orbiting stars beyond the solar system come in all shapes and sizes but mostly fit into a few categories: large and hot gas giants, super-Earths that are slightly larger than our planet, Neptunian planets with gassy atmospheres and rocky cores, and ...

In a new study, researchers from Penn State and NASA’s Jet Propulsion Laboratory analyzed human deep space communications and found that human transmissions are frequently directed toward our own spacecrafts near Mars (lower left), the Sun, and other planets
