Explanation:
At night you can follow this road as it
passes through the Dark Sky Alqueva reserve not too
far from Alentejo, Portugal.
Or you could stop,
look up,
and follow the Milky Way through the sky.
Both stretch from
horizon to horizon in this
180 degree panorama
recorded on June 3.
Our galaxy's name, the Milky Way, does
refer to its appearance as a milky path in the sky.
The word galaxy itself derives from the Greek for milk.
From
our fair planet
the arc of the Milky Way is most easily visible on moonless nights
from dark sky areas, though not quite so bright or colorful as in this image.
The glowing celestial band is due to the collective light of
myriad stars along the galactic plane too faint to be
distinguished individually.
The diffuse starlight is cut by dark swaths
of the galaxy's obscuring interstellar dust clouds.
Standing above the Milky Way arc near the top of this
panoramic nightscape is
bright star Vega, with the galaxy's
central bulge
near the horizon at the right.
