If you could stand on the surface of the newly discovered Earth-sized exoplanet TRAPPIST-1f, what would you see? Presently, no Earthling knows for sure, but the featured illustration depicts a reasoned guess based on observational data taken by NASA's Sun-orbiting Spitzer Space Telescope. In 2017, four more Earth-sized planets were found by Spitzer, including TRAPPIST-1f, in addition to three discovered in 2015 from the ground. From the planet's surface, near the mild terminator between night and day, you might see water, ice, and rock on the ground, while water-based clouds might hover above. Past the clouds, the small central star TRAPPIST-1 would appear more red than our Sun, but angularly larger due to the close orbit. With seven known Earth-sized planets -- many of which pass near each other -- the TRAPPIST-1 system has many candidates that are hoped to have life. Life, however, is a very complicated thing. Finding a planet at the right distance from its star is only the first step in like a million to finding a planet with life. Even if all the chemical elements present in living organisms were found on a planet, they would need to be arranged in just the right way. And then even if the elements were arranged in the right order, doesn't mean you would have life. Because life comes from the Spirit of God.
