A newly discovered planet stuns scientists with its size, potential, and surprising closeness.

You might think Earth is the only neighborhood we’ll ever know—but it turns out we’re not alone. NASA has just revealed a “super-Earth” lurking surprisingly close in space, and scientists are buzzing. This planet, about one and a half times Earth’s size, orbits within the so-called habitable zone of its red dwarf star—meaning it could potentially hold liquid water. As astronomer Aki Roberge of NASA’s Goddard Space Flight Center explains, we now have the tools to ask if there are truly Earth-like worlds out there.
