Steady Jets

When stars are born they eject narrow high speed beams of gas into space. These jet can stream away from the star with speed of more than 300 miles a second! Some of the matter falling into a black hole can also be redirected into a jet. These jets can have speeds that are 99% of the speed of light.

If the jet source is constant then the beam of gas flowing away from it will be steady like a continious stream of water from a garden hose.

Using the Astroflow simulator can you make a steady jet that looks like the image above?
