Astronomical evolution on display at U of T

It's a glimpse into the world of scientists who study the stars, analyze the interaction of matter and radiated energy, and search for extra-terrestrial life.

On March 22, 2013, a team of graduate students in the Master of Museum Studies (MMSt) program at the University of Toronto will unveil their public exhibit showcasing the development of astronomical instrumentation at the David Dunlap Observatory (DDO) and the Dunlap Institute for Astronomy & Astrophysics.

The exhibit, titled 鈥淚nnovators in Instrumentation: Advancing Astronomy at the Dunlap Institute鈥, portrays the evolution of astronomical instrumentation from the last century to today. It features historical artifacts from the DDO and instruments from the Dunlap Institute.

鈥淲hile most people understand that astronomers use telescopes to observe the Universe, they are less aware that astronomers use instruments attached to those telescopes to truly understand the nature of the objects they鈥檙e observing,鈥 says museum studies student, Emily Horne. 鈥淥ne of the mandates of the Dunlap Institute is to develop the instruments that will lead to ground-breaking 诲颈蝉肠辞惫别谤颈别蝉.鈥

Spectrographs鈥攊nstruments that separate starlight according to wavelength鈥攁re fundamental to astronomy. The exhibit includes a brass spectrograph used at the DDO when it began operation in the 1930s, as well as a simple spectrograph used today to teach U of T students.

In addition to spectroscopy, the exhibit spotlights the work being done by Dunlap astronomers to establish a permanent observatory in the Canadian Arctic, with instruments dedicated to the search for planets beyond our Solar System. It also describes the work being done in the development of key instrumentation for the Thirty Meter Telescope which, when it is operational later this decade, will be the largest optical telescope every built. The exhibit also highlights the Dunlap鈥檚 own efforts to search for extraterrestrial intelligence, commonly known as SETI.

The exhibition project is a full-year course in the second year of the MMSt degree. As an alternative to doing a thesis, students can choose to do the project to gain hands-on experience with all facets of exhibition work, including design, curatorial practice, project management and collections management.

鈥淥ur team learned about this project through the University of Toronto Scientific Instruments Collection which preserves research tools used throughout history at U of T," says student Lauren Herzog. "We were excited for an opportunity to bring history and science together. The Dunlap鈥檚 work is fascinating, and now we get to share their work with the public.鈥

Over the course of the academic year, the students immersed themselves in astronomy and instrumentation, meeting with Dunlap astronomers to discuss their work.

鈥淎s we learned more about the Dunlap and were given the opportunity to work with some of the institution鈥檚 incredible faculty and postdocs, we knew we鈥檇 chosen a great project," says student Samantha Haddon. "They鈥檝e been amazing to work with, and have explained complex astronomical principles, instruments and the discoveries they鈥檝e lead to. We hope we鈥檝e done the same for people who visit the exhibit.鈥

In addition to Haddon, Herzog and Horne the team of students includes: Laura Imrie, Claire MacDonald-Matthews and Amanda McGee.

鈥淚nnovators in Instrumentation鈥 is free and open to the public and can be seen Monday through Friday, 9 am to 5 pm until October 2013, on the third floor of Victoria College.
