Kitt Peak National Observatory

This weekend the kids and I visited Kitt Peak National Observatory (NOAO), located at the top of route 386 on the Tohono O’odham Nation, 56 miles outside of Tucson, AZ. Kitt Peak is home to one of the largest arrays of radio and optical telescopes in the world. I signed us up for the three daytime tours: the McMath-Pierce Solar Telescope Tour (10-11am), the 2.1 meter telescope (11:30-12:30pm), and 4-meter Mayall telescope (1:30-2:30pm). All three docent-led tours cost $13 per person, a steal in my opinion.

According to NOAO, the McMath-Pierce Solar Telescope is “the world’s most striking solar telescope” and is “used by astronomers primarily during daylight hours to study the nearest star, the Sun” because it can “see farther into the infrared than any other solar telescope.”

Here are a few more images from the McMath Pierce Solar Telescope. In the first picture Gigi, our docent, explained that this is the control panel astronomers use for the telescope. Interestingly, it is made by the same company and in the same era as they control panels at the Titan II Missile Museum! The second image is also in the control room, where the image the telescope collects comes through a hole in the ceiling and onto an image processing station. Way cool!

The 2.1 meter telescope was the first major solar telescope on Kitt Peak, seeing its first light in 1964. According to NOAO, “numerous important discoveries were made at the 2.1-meter. It first detected very distant clouds of hydrogen gas between galaxies, known as the Lyman-alpha forest. It observed the first example of gravitational lensing (as predicted by Einstein) and the first pulsating white dwarf star. Research into the rotation rate of spiral galaxies that began at the 2.1-meter eventually led to our current understanding of the existence of dark matter in the Universe.” I took this black and white image while we were inside the viewing area of the actual telescope. I had no idea this is what they actually look like.

The 4-meter Mayall telescope is the largest telescope on Kitt Peak weighting just shy of 300 tons. Seeing its first light in 1973, it is “one of the most scientifically productive telescopes in the world. …For over 40 years the Mayall has been involved in cutting-edge astronomical research, most notably in understanding the size and large-scale structure of the visible universe. It has also been used in research on exoplanets (planets that orbit stars other than the Sun).” Currently, astronomers on Kitt Peak are retrofitting the Mayall with DESI, an acronym for a unique spectrometer which will allow the telescope to quickly obtain the spectra of 5,000 objects simultaneously.

Here are more images from this gigantic telescope. The first two images are from inside the viewing area of the actual telescope. The last three are from inside and outside the environment viewing area of the telescope. From here you get a bird’s-eye view of surrounding landscape of the Tohono O’odham Reservation.

A lot of the tour went over my kids’ heads, but for me, the knowledge I gained about the field of astronomy blew my mind. Of course, I was particularly interested in the history behind it all (for example, the observatory was built in the fifties in response to the space race and the Cold War) but the details behind the science used here took my breath away. Highly recommend!


Tucson’s Mysterious Manning House

This week my photography class and I have been given special access to the grounds of the Manning House. Here is a preview of the history behind this historic building in downtown Tucson, AZ.

M.A. Kleen

The historic Manning House sits opposite a traffic circle along West Pso Redondo, near downtown Tucson, Arizona. When Levi Howell Manning built the mansion for his family in 1907, it was situated on 10 acres of fertile grazing pastures. Designed by architect Henry Trost, it is an eclectic combination of Spanish Colonial, Territorial, Italian Renaissance, and Prairie style architecture. It has been used for many purposes over the years, but rumors remain that it is haunted by either Mr. Manning or his son.

Levi H. Manning, son of a Confederate veteran, was born in North Carolina in 1864. While at home on summer break from the University of Mississippi, a fraternity brother and he played a prank that went awry when an elephant they acquired from a local circus escaped and went on a rampage around town. Manning’s mother advised him to leave before his father found out, so…
