We felt that the star could not produce you - or your race without the presence of benevolence.

Even a dark star produces heat, but less and less of it all the time.

Or they could be produced by huge stars 10 to 20 times as massive as the Sun.

Most stars produce powerful winds either when they are very young or very old.

The star produced a high energy outburst that did not lead to stellar collapse.

The energy produced by stars radiates away from them.

Along the way, however, these same stars produce carbon, oxygen and nitrogen, the elements essential for life.

Curiously, how stars produce jets is an open question.

There is no clear explanation of how the central star could produce the nebula's shape:

The arms are dusty regions of star formation where massive young stars produce a blue tint.
