Vimy Ridge
the spirit of death
kissed you
on this ridge
your work is done
no triumph no glory
but for ever
silent

Stellar Wind - Jan Theuninck, 2013
Interaction of stellar wind with diffuse nebulae.
A stellar wind is a flow of neutral or charged gas ejected from the upper atmosphere of a star. It is distinguished from the bipolar outflows characteristic of young stars by being less collimated, although stellar winds are not generally spherically symmetric.
Different types of stars have different types of stellar winds.
