An artist's concept depicts a possible moon (lower left) orbiting the planet WASP-49b (right). The moon is hinted at in recent observations. If confirmed, it would be the first known exomoon. The moon and planet are so close to their parent star (top left) that the moon's outer layers are streaming away into space. [Thibault Roger/University of Bern]
