The jets of T-Tauri stars differ from the bipolar outflows of stars both younger and older, in that these jets reside in the visible spectrum of light and are typically classified as Herbig-Haro objects. The jets last only a few thousand years, being shot forth at up to 250 km/s in short bursts rather than steady beams. As the ionized gas leaves the region of the star and collides with non-ionized gases several light years away, bright and cloudy "caps" can be seen in some cases, making for remarkable and somewhat symmetric imagery.
