This New Hubble Pic Reveals a Dramatic Cosmic Phenomenon in All Its Gory Detail - ScienceAlert

As a protostar spins, material in the cloud around the object forms a disk.

This disk of material spools into the forming star, drawn in by its strengthening gravity, which grows as the protostar gains mass.

As the protostar grows, it starts to produce a powerful stellar wind, and material falling into the protostar starts to interact with its magnetic fields, flowing along magnetic field lines to the poles, where it is blasted into space in the form of powerful plasma jets.

The wind and jets are known as stellar feedback, and they help to blow away material from around the protostar, slowing and eventually cutting off its growth. When the star gains enough mass to produce sufficient heat and pressure in the core, nuclear fusion will kick off – et voila, your star is now on the main sequence.

Star formation is a relatively long process on human timescales, taking place over millions of years, which means we will likely never be able to see it from start to finish.
