When we look up to the night sky we see beyond Earth’s protective atmosphere to the planets in our solar system and the universe of stars that comprise our galaxy, the Milky Way galaxy.
Observatory Director, Dr. Eileen Ryan, explains this image, “I’m observing with the telescope from the control room in the observatory building. The image is the telescope as I command it to move to a night sky object (the picture is looking straight down at the primary mirror). The black circle is a positioning display in the software that controls the telescope motion.

To the eyes of astronomical researchers and faculty at New Mexico Tech in Socorro, New Mexico, there’s a world of Near Earth Objects (NEOs) – and occasional Interstellar Objects (ISOs) – between Earth and space. Thanks to the whole-hearted welcome extended to me by Eileen V. Ryan, PhD, Director of the university’s Magdalena Ridge Observatory (MRO), I broadened my awareness of the study of these natural and human-made bodies. Dr. Bill Ryan, MRO research scientist, joined his wife and collaborator in describing their work with MRO’s 2.4 meter telescope. A responsive team, NMT personnel and guest researchers search for asteroids that could be on a trajectory to collide with Earth and, among other initiatives, observe human-made satellites to determine possible threats. MRO partners with major space agencies tasked with maintaining national security.





CLICK ON THE IMAGE This gif shows the unique path of the strange object that zoomed through our solar system over the past few months.    Object named A/2017 U1 first spotted in data from the Pan-STARRS 1 telescope at the University of Hawaii Institute for Astronomy, October 19,2017. “This is the first time in history that we’ve discovered an object that has come from outside our solar system and passed through our solar system,” said physics professor Van Romero, the vice-president for research at New Mexico Tech, on November 2, 2017.   He continued, “Right now, the Magdalena Ridge Observatory is taking the lead on this interstellar visitor. Magdalena Ridge Observatory is the flagship telescope for NASA to characterize those objects.” Eileen Ryan added, “The trajectory of the object as it’s leaving our solar system [will] give us the information we really need to discover – where did it come from?”Image credit: NASA_JPL-Caltech

Astrophysicist Dr. Daniel A. Klinglesmith III, whose commitment to offering astronomy experiences to the public includes conducting star parties, invited me to the Etscorn Campus Observatory, where I looked over his shoulder at his computer screen, which is connected to Etscorn’s 14-inch Schmidt Cassegrain telescope, as he tracked an asteroid he is studying. He is advisor to the NMT Student Astronomy Club, which takes responsibility for the operation of Etscorn, where monthly star parties are hosted. Dr. Klinglesmith’s research focuses on asteroid light curves.
The Magdalena Ridge Observatory, primarily a research facility, is located at the top of a 10,612 feet peak in Cibola National Forest. I knew that access is restricted, but memories of other astronomical sites I’ve visited prompted me to express interest in seeing the MRO. I pictured a paved road to a spacious summit. I was delighted when Eileen Ryan arranged for me to meet Craig Wallace-Keck, who would give me a tour and a ride “in his 4-wheel drive truck, necessary to negotiate the rugged terrain.” Wallace-Keck regularly checks systems at the observatory and keeps all manner of support equipment functioning. Agile as an acrobat, he maneuvered the truck up the 6,000 feet elevation gain, effortlessly taking switchbacks on the narrow, red gravel road that looks down through the vital forests of Water Canyon. He spoke of minus 38 degree temperatures, 8 feet of snow, gale force winds, 50 truckloads of materials being hauled up this road to build the observatory.
Then, we were inside the quiet space of the control room, equipped for scientists to pursue their studies, the dome of the observatory adjacent, with its great eyelid to be opened to the sky so that the remarkable 2.4 meter mirror of the telescope might look out, a formidable tool for gathering light.

I have written this preamble to the work of the Magdalena Ridge Observatory and provided illustrations and a Resources section as guides to further investigation. In closing, I have a message from Dr. Eileen Ryan. I asked her, “What is most important to convey to readers?” She said, “Tell girls and women that careers in science do not require waiting for or giving up their personal fulfillment in love, work and knowledge. When my son Liam was a baby I was scheduled to present a paper at the American Astronomical Society. I, as well as other female scientists with small children, told the conference coordinators that they had to offer child care, and they did!”

See illustration of Liam Ryan working on a Science Fair project to measure gravity at different elevations. Eileen Ryan wrote, “He won 2nd place in the State. His objective was to take data to see how gravity changed from down in the valley of Socorro, 4200 feet, again a bit higher up at our home, 6500 feet, and then at 10,612 feet at the telescope. It kept him busy while we were observing! He correctly measured that gravity decreased with increasing distance from the center of the Earth.”

    Thanks for the nice article about Magdalena Ridge Observatory, Etscorn Campus Observatory and their facilities and uses.

    Looking forward to people enjoying the dark skies of Magdalena’s Enchanted Skies Star Party.
