The image on the right shows is a magnified view of NGC 1999, showing twin jets produced by a young star. Each jet ends in a bow shock, named after the analogous process of a ship’s bow pushing through water. Each of these jets in moving at velocities close to that of light. However both in the case of the jet produced by this young star, and the jet produced by the quasar 3C175 only one jet is visible.
