September Skies
September marks the beginning of what stargazers
recognize as the best time of year for exploring
the night sky. The cool dry air makes stars
sparkle! The days are rapidly shortening; as a
consequence the normal procession of the
constellations across the sky seems to halt.
This allows us to enjoy the delights of summer,
but without the bugs!
On moonless nights the great Milky Way takes
center stage. Often mistaken for clouds, the
Milky Way subtly illuminates the night sky. Trace
its meanderings from beyond Cassiopeia in the
northeast to Sagittarius on the south horizon.
Sagittarius the Archer is perhaps the most
interesting constellation of the late summer
sky. It contains bright star clouds, clusters of
stars, as well as bright and dark nebulae.
Scanning this region with binoculars under a dark
sky can dazzle the mind. Due to our latitude,
this region of the sky stays fairly low on the
southern horizon. A clearing that exposes this
area of the sky will provide the best views.
The stars of Sagittarius forms an asterism (see
star chart) called “The Teapot”. This becomes
obvious once you’ve seen it. If you notice a
bright patch along the Teapot’s spout (right
side) you are witnessing what is known as the
Great Sagittarius Star Cloud. It appears like
steam “pouring out” of the teapot! Just to the
west of this star cloud marks the center of our
galaxy, a fact not to be forgotten when gazing in
this direction.
The Harvest Moon illuminates the sky all night
long on the 15th. The Moon also takes part in a
close pairing with Jupiter the evening of the
9th. The planet Jupiter can be seen as a
brilliant white beacon due south on any clear
September evening.
