Astronomy Picture of the Day

Shown her is the Pleiades star cluster destroying a passing cloud of gas and dust. The Pleiades is the brightest open star cluster that can be seen from Earth and is visible from almost any northern location with the naked eye. The star cluster is devouring a cloud part of Gould's Belt, which is a ring of young star formation in the Milky Way Galaxy. Pressure from the stars' light repels the dust in thenebula, with smaller dust particles being repelled more strongly.Parts of the dust cloud have become filamentary and stratified, as seen in the above deep-exposure image.
