Explanation: The well-known Pleiades star cluster is slowly destroying part of
a passing cloud of gas and dust. The Pleiades [7] is the brightest open
cluster of stars [8] on Earth's sky and can be seen [9]  from almost any
northerly location with the unaided eye [10] . The passing young dust cloud is
thought to be part of Gould's Belt [11] , an unusual ring [12]  of young star
formation surrounding the Sun in the local Milky Way Galaxy [13] . Over the
past 100,000 years, part of Gould's Belt [14] is by chance moving right
through the older Pleiades [15]  and is causing a strong reaction between
stars [16]  and dust. Pressure from the stars' light significantly repels the
dust [17]  in the surrounding blue reflection nebula [18] , with smaller dust
[19]  particles being repelled more strongly. A short-term result is that
parts of the dust cloud have become filamentary [20]  and stratified [21] .
The featured deep image also captured Comet C/2015 ER61 [22] (PanSTARRS [23] )
on the lower left.
