A planet is forming in an Earth-like orbit around a young star

Discs of dust and gas that surround young stars are the formation sites of planets. New images from the Atacama Large Millimetre/submillimetre Array (ALMA) reveal never-before-seen details in the planet-forming disc around a nearby Sun-like star, including a tantalising gap at the same distance from the star as the Earth is from the Sun.
