Simulation -- 3-D Representation (IMAGE) University of Leeds Caption This is a 3-D visualization of the simulated nebula, showing the dense disc-like molecular cloud in red, the tenuous stellar wind focused away from the disc in blue and the magnetic field lines in grey. The magnetic field is of key importance in forming a disc-like, not spherical, molecular cloud. Credit C. J.
