An international team of astronomers has been able to study the short-lived disc of material around a young star that is in the early stages of making a planetary system using AMBER on the Very Large Telescope. For the first time a smaller companion could be detected that may be the cause of the large gap found in the disc. Future observations will determine whether this companion is a planet or a brown dwarf.
