On yet another lovely sunny day we
set off to explore Kitt Peak National Observatory. We followed highway 86 until we reached highway
386,
we took a left and followed the road
up the very steep, curvy mountain road.
There were great views, and, unlike
Mount Lemmon we didn’t see any cyclists.
The original way up the mountain was
a 7 mile long, very steep, very rough dirt road that literally went straight up
the side, the road is still there and apparently very occasionally someone will
ride a motorbike up that way.
The observatory, which was established
in 1957, occupies 200 acres of the summit. Our
guide told us that Kitt Peak is the second most sacred peak of the
Tohono O’odham people and is known
as I'itoli’s garden, Baboquivari Peak, below, is the most sacred peak and home
to I'itoli, the Creator.
There are 25 optical and 2 radio
telescopes on the summit of Kitt Peak, and in 1985 the National Science Foundation signed a
perpetual agreement with the Tribal Council of the Tohono O’odham Nation for
the use of the mountaintop as long as only scientific research facilities are
maintained there.
Kitt Peak National Observatory is
part of the National Optical Astronomy Observatory (NOAO) which is based in
Tucson. NOAO also operates an
observatory in Chile and provides US astronomers with access to the Gemini
North and South telescopes in Hawaii and Chile.
The first tour took us to the 2.1M
telescope that was built in 1964, which is still in use on a nightly basis.
Our next stop was the Meade Solar
Telescope Array
where we were able to look through
a telescope at the sun and see sunspots and solar flares, it was fascinating.
Sadly we hadn't allowed ourselves enough time to look
at the McMath-Pierce Solar Telescope as well.
After some lunch I headed off to visit
the Mayall 4M Telescope, our first stop was actually the car park where there
is what looks like a concrete donut.
It’s actually an almost exact
replica of a telescope mirror and is used when setting up a telescope instead
of the highly polished mirror, just in case after all imagine something
happening to the actual mirror!
On the way up to the Mayall 4M Telescope
we saw an open radio telescope being re-positioned.

From the observation deck part way
up the telescope we had a great view of the site.
The observatory closes at 4.00
p.m. but if for any reason you were there on a tour and left after dark, then
for the first mile down the mountain you can’t use your headlights, you simply
follow the tail lights of someone who knows the way. I bet that’s pretty spectacular and probably
the longest mile you’d ever drive!
On both the tours our guide was
very informative and knowledgeable, not too technical and at the time it all
made perfect sense. At the end of the tour
our guide touched on the expanding universe, dark matter and dark energy now, to me,
that really sounds like something out of Star Trek!
Have fun, we are!
We drove by the Kitt and because of schedule couldn't stop. Looks like we missed a special place.
ReplyDeleteOh it was, I really enjoyed it, if you're back that way again it's definitely worth visiting. Have fun!
