With an estimated age of only a few 104 years, IRAS 16293-2422 is one of the youngest known multiple stellar systems. In the last two decades, it has been repeatedly observed at centimeter wavelengths using the VLA. While it has been a triple radio source in all observations prior to 2006, it now contains five sources. The two new objects appear to to be the result of a spectacular nearly symmetric bipolar ejection that occurred less than 3 years ago. Thus, we seem to have witnessed the very birth of an HH system.
