... When a cloud starts to collapse, it should fragment. Fragments then collapse on their own, fragmenting further. End product is 100’s or 1000’s of dense clumps each destined to form star, binary star, etc. Hence a cloud gives birth to a cluster of stars. ...

THE LIFE CYCLE OF STARS
... Young stars emit jets of intense radiation that heat the surrounding matter to the point at which it glows brightly. These narrowly-focused jets can be trillions of miles long and can travel at 500,000 miles per hour. These jets may be focused by the star's magnetic field. The protostar is now a sta ...
