To support alien life, a planet doesn’t have to be exactly like Earth, but it does need a few key ingredients. First, it should orbit its star at the right distance, where temperatures allow liquid water to exist.

Alien life could exist on hot, rocky planets, sustained not by water but by a type of salty fluid, new research suggests. Reading time 3 minutes The search for alien life usually hinges on finding the same conditions that sustain life on Earth. But what if ...

Who hasn't looked into the sky and wondered if there's life out there, somewhere, looking back at us? Is it possible there's alien life closer to home — within the bounds of our solar system? The short answer is yes, there are several places researchers ...

PROOF of alien life is one step closer to being found thanks to a massive earthquake-proof telescope that’s near completion in the middle of the desert. First photos of the eye-in-the-sky rising

There might be many more planets that could be home to aliens than we thought, according to a new study. For years, scientists have searched for life in the “habitable” or “goldilocks” zone – where it is neither too hot or too cold to have liquid ...

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 communications with other planets, much like NASA’s Deep Space ...

A new study suggests a novel approach in the long-running scientific endeavor to find intelligent life beyond Earth. Instead of casting a wide, speculative net across the cosmos, researchers from Penn State and NASA’s Jet Propulsion Laboratory propose a ...
