The Rosetta spacecraft is investigating comet 67P/Churyumov-Gerasimenko since mid-July 2014. Jet structures have been identified in the coma indicating anisotropic outgassing activity from the nucleus surface. We will report on the physical characteristics of the gas and dust jets including their brightness and density enhancements, radial expansion, association with source regions and time evolution.
