Observing the launch of a jet during star formation confirms predictions

Observations have mapped the distribution of gas velocities in a circumstellar disk wind for the first time. The high spatial resolution required for these observations is achieved by measuring the maser emission of water molecules. These findings validate theoretical predictions from the 1980s and can be replicated by modern numerical models.
