Explanation:
The well known Pleiades star cluster is slowly destroying part of a passing
cloud of gas and dust. The Pleiades is the brightest open cluster of stars on
Earth's sky and can be seen from almost any northerly location with the unaided
eye. The passing young dust cloud is thought to be part of Gould's belt, an
unusual ring of young star formation surrounding the Sun in the local Milky Way
Galaxy. Over the past 100,000 years, part of Gould's belt is by chance moving
right through the older Pleiades and is causing a strong reaction between stars
and dust. Pressure from the stars' light significantly repels the dust in the
surrounding blue reflection nebula, with smaller dust particles being repelled
more strongly. A short-term result is that parts of the dust cloud have become
filamentary and stratified, as seen in the above deep-exposure image.
