Deep and dusty
Which is best for a beach bonfire? Full moon? Or moonless night?
There's something magical about moonlight on the sea. Something that invites a swim. And romance.
But then –- there's the myriad of stars and the Milky Way you can see on a moonless night. "What's that?" a neighbor asks, pointing to the Pleiades, shining with a special brightness.
"How many stars do you see?" I ask. They are called 'the Seven Sisters.""
"Six." "And I tell the story of the missing Pleiad, snatched away by one of the seven brothers of Ursa Major.
"There are actually more than a thousand stars in the cluster, only six of which are bright enough to be reliably seen with the naked eye. The most I have seen without optical aid is nine, when my eyes were younger and sharper, under a sky of exceptional darkness and clarity.
"Where is the missing Pleiad now?" "Just rising." I show her the Big Dipper standing on its handle in the northeast, with brother Mizar and little kidnapee Alcor.
What I can't show her is the dust cloud that is passing through he Pleiades, being pushed into wisps and streamers by the pressure of starlight.
