This book deals with amazing celestial bodies - exoplanets. These planets do not orbit our Sun, but other stars. The diversity of exoplanet species is mind-boggling: hot gas giants and cold mini-replicas of Neptune, ocean worlds and super-Earths orbiting their stars or floating freely in outer space. What are these worlds? How did scientists manage to detect them? And, of course, is there life there? Welcome to an exciting journey! For a wide range of readers.
