July Skies
The Earth is but a perch to view the larger
Universe. The Milky Way galaxy’s visibility for
the greater part of human history was a
birthright. Our well lit technological age has
reduced or eliminated its visibility, leaving it
to the few rural and remote areas left.
Fortunately, Maine has the largest area of
naturally dark skies east of the Mississippi.
This is dark sky country.
Prime Milky Way observing will be on moonless
nights which occur the latter half of the month.
An optimal viewing location will include a good
southern horizon as well as a clear overhead.
Our Milky Way Galaxy and its dark rift appear
from Cassiopeia in the north, overhead in Cygnus,
through Aquila, Ophiuchus, and ends most
spectacularly in Sagittarius near the southern
horizon. The Star clouds that populate Maine’s
summer Milky Way shine with a peerless light,
subtle yet starkly wonderful. Nothing is more
awe inspiring. It stimulates our sense of wonder
and a zest for learning.
Lunar events for July include a close encounter
with Scorpius’ brightest star on the 3rd. The
Moon will be seen hanging to the lower right of
red-orange Antares. On the evening of the 25th,
Saturn is in conjunction with the Moon. Saturn
will appear to the upper right of our natural
satellite. Spica, the brightest star in Virgo,
tops our Moon on the 27th. All these events will
be visible in early evening. The scene will be
most striking in deep twilight.
The Delta Aquarid meteor shower peaks on the
28th. The radiant is rather low on the southwest
horizon after midnight; however, up to twenty
meteors per hour may be seen. The first quarter
moon will set by 11:00 and will increase the
chances of seeing them.
