Explanation:
Near dawn on November 19
the Pleiades stood in
still dark skies over the French Pyrenees.
But just before sunrise a serendipitous moment was captured in this
single 3 second exposure;
a bright meteor streak appeared to pierce the heart of
the galactic star cluster.
From
the camera's perspective,
star cluster and meteor were poised directly
above the mountain top observatory on the
Pic du Midi de Bigorre.
And though astronomers
might consider
the Pleiades to be relatively close by, the
grain
of dust vaporizing
as it plowed through planet Earth's upper atmosphere
actually missed the cluster's tight grouping of
young stars by about 400 light-years.
While
recording a night sky
timelapse series,
the camera and telephoto lens were fixed to a tripod on
the Tour-de-France-cycled slopes
of the
Col du Tourmalet
about 5 kilometers from the Pic du Midi.
