Description

Want to be a top notch candidate for hosting alien life? Then there's a few key requirements you should be aware of: Ideally, you're a large object like a moon or a planet; scientists suspect you also have an atmosphere and water; plus, you should orbit your star from a nice mid-range distance — in the "Goldilocks Zone" of habitability. Until recently, you would be competing against TRAPPIST-1 e. It's a planet outside of our solar system. TRAPPIST-1 e is also only 40 light years away, rocky and the same size as Earth, which prompted researchers to investigate whether it also has an atmosphere — and the potential for alien life. A team of researchers has been investigating TRAPPIST-1 e to learn more about its potential. Their answers, recently published in the Astrophysical Journal Letters, say a lot not just about this exoplanet, but about how scientists should refocus their hunt for alien life.
