Under The Heber-Overgaard Night Skies
By Ron Firestone,
Star Quest Observatory
Every now and then, I like to
“suppose.” When we were kids in school, and got
caught staring out the window, we were reprimanded for
daydreaming. In the “grown-up” world, we refer to
it in a more adult way: supposing. Let’s suppose for a
little bit.
Suppose you’re the captain of an
alien spaceship. You’re on a recon mission to check up on
Earths progress on your way to the Omicron Delta sector
(wherever the heck that is) of our galaxy, the Milky Way. You
tell your science guy “Ni” (pronounced Ni) to get
you the landing coordinates to the leader of this intelligent
civilizations office. In two thirds of a nano-second, Ni
replies.
“Well, there’s a place called
Washington,

The Large Binocular Telescope atop Mt.
Graham, just outside of Safford, Arizona. Each mirror is a
whopping, 27.54 feet across, and weighs in at 17.64 tons.

D.C., with a large white house where their
leader lives. It happens to be right next door to their
military intelligence”. You reply to Ni in one third of a
nano-second “nonsense you were at the briefing,
there’s no such place, it doesn’t exist. It’s
another one of their ludicrous government cover-ups, like us.
Look, we just crossed 60,000 parsecs of empty space, why would
we even consider landing in the middle of more”? Ni
replies, “that is a very logical answer captain, but
allow me to finish. My ETIS (short for ExtraTerrestrial
Intelligence Scanner) also tells me that all the intelligence
for this species is in a place called Arizona.
Per capita, they have more astronomical
observatories and institutes of scientific education and
research than any other place on their planet. I would advise
that we land there and make first contact with this highly
advanced race.” “Duly noted”, you reply to
Ni.
How right Ni is! Our great state is a
special place to live! Aside from being one of the last truly
dark sky frontiers of our country, Arizona seems to have been
created for astronomy. At seven major observatory sites around
the state, there are 60 giant optical telescopes peering into
the sky every night. By giant, I’m referring to any
telescope with an objective lens or mirror from one meter (one
meter is 3.28 feet) to 8.4 meters (27.54 feet) in diameter. In
fact, many of them should be referred as
“monstrous”.
For example, the Large Binocular Telescope
(LBT) at Mt. Graham International Observatory, Safford, AZ. It
sports two enormous mirror objectives, each 27.54 feet in
diameter and weighing almost 18 tons. That’s a combined
telescope with a 55.08 foot objective, making it the most
powerful telescope on Earth or in space! The Mayhall 4 meter,
or 13.12 foot reflector telescope, sits atop Kitt Peak 50 miles
southwest of Tucson.
This is only one of their 24 research
telescopes, including the largest solar research telescope in
the world. Thirty miles south of Tucson is the MMT Observatory,
a 6.5 meter (21.33 foot) optical telescope, located on the
summit of Mt. Hopkins at the Fred Lawrence Whipple Observatory.
As we head north to Flagstaff, we find Lowell Observatory with
its famous 24" inch Clark refractor telescope that Clyde
Tombaugh used back in 1930 to discover Pluto. Their newest
addition, the 4.2 (13.78 foot) meter Discovery Channel
Telescope will be operational in 2010. Just outside Flagstaff,
is the United States Naval Observatory (USNO) with its 1.55
meter, 1.3 meter, and 1 meter telescopes. Astronomers around
the world compete heavily to obtain a few hours at an Arizona
observatory! There’s more, many more than I can write
about in this entire paper.
Most of Arizona’s 21 community
colleges teach accredited courses in physics and astronomy.
Nearly a 100% of their graduating students move on to one of
Arizona’s three major universities.
The University of Arizona (U of A), Arizona
State University (ASU), and University of Northern Arizona
(NAU), has some of the largest and finest physics and astronomy
departments in the country. U of A has the Lunar Planetary Lab
(LPL) that is famous for data recovery and analysis from our
planetary probes, many of which are still in operation today.
Also at U of A is the Steward Observatory Mirror Lab where most
of the optics for our planetary probes and gargantuan
observatories are made. It’s one of the largest optics
labs in the world. ASU built the Mars Thermal Emission
Spectrometer (TES) to analyze Martian soil by the Phoenix Mars
Lander. In addition, ASU has instruments on many other active
spacecraft in our Solar System. NAU works directly with NASA in
analysis of data sent back by the spacecrafts. It’s a
very prestigious role for a student to be selected on a NASA
team.
All the major observatories in Arizona
offer public science outreach programs or some type of activity
that is free to the public, or a very nominal fee to cover
operation. Arizona has some of the largest astronomy clubs in
the country, and many small towns around the state have an
astronomy club as well.
Our club, the Heber/Overgaard Astronomy
Club (HOAC) is a good example. Arizona is a leading state in
private observatories that use high quality instruments and
offers them to communities as free public science outreach
facilities.
Star Quest Observatory (SQO) in
Heber/Overgaard is such a facility, and it’s free of
charge to young and old alike that want to nurture their
interest in astronomy.
Arizona should be referred to as the
“Astronomy State”, but all said, it’s pretty
tough to compete with the Grand Canyon. Most of the sites
listed above are accessible to the public, and only a few
gallons of gas away. Access roads are safe, with well
maintained paved roads; just take it slow on the switchbacks. I
encourage everyone, especially parents with school-aged
children, to visit these magnificent institutions. I promise,
you and your children will never see Arizona in the same light
again. No pun intended. For more information on visiting times
and how to get there, go to

astronomy in Arizona.
The Geminid meteor shower on the 13th, one
of the years largest is expected to be a flop this year due to
being washed out by the Moon. However, the lesser known Ursid
meteor shower that peaks on December 22, will give us a nice
show at 30 meteors an hour. Look north from 11:30 P.M., to
about 3 A.M. our time. The Ursid shower is the results of Earth
passing through comet 8P/Tuttles dust trail.
Planet lineup for December - Evening sky,
Mercury (southwest), Venus (southwest), Jupiter (southwest),
and Uranus (south). Midnight sky, Saturn (east). Morning sky,
Saturn (south).
Full Moon occurs on the 12th, and New Moon
on the 27th.
Winter solstice happens on the December
19th at 4:04 A.M., our time. This is the exact moment at which
the Earth is at its maximum tilt away from the Sun, indicating
the beginning of winter.
Did you know…that many of our
exploration spacecraft are powered by less energy than it takes
to light a hundred watt light bulb? The Mars rover Spirit,
cruises Mars surface, sends back data/pictures across 100
million miles of space, and maintains its internal temperature,
all on less than 250 watts of electricity. That’s
equivalent to lighting a 100-watt light bulb for 2.5 hours.
Ni and all of us at Star Quest Observatory
bid you all a very Merry Christmas, and a sincere “Thank
You” for your interest and support in 2008!
Until next month, get up, get out, and get
into “What’s Up.”
Star Quest Observatory closes October 31 to
May 1 for the winter.
