Alien Life Might Look Nothing Like We Expect

Aliens might be out there, just not like we imagine. 🔭🧪

Paul M. Sutter, a theoretical cosmologist and science communicator, explains that by only searching for life like our own, we might be overlooking alien life entirely. Our search focuses on organisms that resemble Earth-based biology because it’s the only kind we know how to detect. From the elements it needs to the chemical changes it leaves on a planet, Earth-like life guides our tools and strategies. But if life evolved differently on other worlds, we may not even recognize it.
