Reflection nebulae – The Pleiades
• Cluster of new stars
– Visible to unaided eye
in western Taurus
– Stars form in clusters – most of
which slowly spread apart.
• Reflection nebula is reflected
sunlight
– Can see stellar-like spectra with
absorption lines
– Blue light scattered more
efficiently than red
• Pleiades didn’t form here – just
moving through this cloud of
dust.
