Some 40-light-years from Earth, a planet called TRAPPIST-1e offers a heart-stopping view: brilliant objects in a red sky, looming like larger and smaller versions of our own moon. But these are no moons. They are other Earth-sized planets in a scectacular planetary system outside our own. These seven rocky worlds huddle around their small, dim, red star, like a family around a camfire. Any of the could harbor liquid water, but the planet shown here, fourth from the NASA’s Spitzer Space Telescope. The planets also are excellent targets fro NASA’s James Webb Space Telescope. Take a planet-hopping excursion through the TRAPPIST-1 system.
