However, most of the excess gas and dust around the star does not form into planets. Instead, the material is blown away into space by the tremendous explosive power of the star. When the star is still young, perhaps only a million or two years old, it is still surrounded by huge quantities of leftover gas. Planets have not yet formed. Although the star has already started to explode, material from its surrounding disk is still flowing toward the star, but not all of its makes it there.
Some gas is grabbed by the star's considerable magnetic field.
This doomed material passes along the lines of magnetic force surrounding the star and is then blown outward into space from its north and south magnetic poles. The Hubble images reveal the evolution of the jets of glowing gas heaving outward from young stars. A typical outburst may last only weeks, but the burst pulses again and again with the ebb and flow of the star's constantly magnetic field and the build-up of gases near the star. The time lapse movies of XZ Tauri reveal a heaving bubble of hot gas being forced 60 billion miles into space at almost 300,000 miles per hour. If you have ever wanted to appreciate the power of a star, these images and movies are definitely worth a look.
