There are estimated to be trillions and trillions of planets orbiting the stars beyond our solar system. These alien worlds are called exoplanets, and Live Science is as curious as you are about what might be on them.
That's why our expert writers and editors track interstellar research, whether it's the discovery of a new class of exoplanet, a mirror-like exoplanet that "shouldn't exist," or the possibility of the first exoplanet outside the Milky Way. So whether it’s extreme exoplanets or just memorable facts, get the latest exoplanet news, features and articles here.
