This soft-spoken bedtime story is a journey to the discovery of exoplanets. We will visit some of them, like Proxima Centauri B, OTS 44 and Kepler 438b. I will also tell you about the different types of planets and stars, including stars that no longer shine like old white dwarfs or neutron stars; methods to discover planets that are invisible from Earth, like Transit Photometry or Doppler Spectroscopy; and astrobiology: the field of research that studies the possibility of extraterrestrial life.
