Hubble Captures the Violent Birth of a Star

The Bad Astronomer writes "In what is one of the most staggeringly beautiful Hubble pictures ever taken, a newly-born massive star is blasting four separate jets of material into its surrounding cocoon, carving out cavities in the material over two light years long. But only three of the jets appear to have matter still inside them, and the central star is off-center. This may be a gorgeous picture, but the science behind it is equally as compelling."

Stellar formation?

[SirGarlon]

This may be a naive question (and will almost certainly be derided as such). I remember from Astronomy 101, many years ago, the prevailing idea about stellar formation. But I don't remember anyone ever explaining studies that verify the hypothesis is valid. What I'm saying is that it's pretty obvious this is a star surrounded by a cloud of material (gas or dust, I can't remember), but how do we know the star is forming rather than, say, dying? Or are we just supposed to take it on faith because we read it in a book?

A related question-- this is an awesomely cool picture, but does it or does it not tell us much about how stars form?

To continue the christmas tree analogy, what Hubble does for our eyes is a little like what some enterprising pixel-slinger might do for a person with some form of color blindness; sure, the viewer might not be able to distinguish between red and green (or blue and yellow) lights on the tree, but they can still be rendered using the available spectrum into something which conveys the beauty and complexity of the overall display.
