Using ESO's Very Large Telescope 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. 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.
Planets form from the discs of material around young stars, but the transition from dust disc to planetary system is rapid and few objects are caught during this zcutb [7].
