From textbook to telescope: Campus observatory adds shine to astrophysics courses

A low-cost, high-value observatory with a passing resemblance to a backyard shed has been arrange within the grounds of the College of Tub. The observatory is proving to be a game-changing experimental software for undergraduates finding out occasions in space, say lecturers on the college.

The timber cabin—positioned on the college campus and designed to offer astrophysics college students hands-on expertise observing objects within the night-sky—was constructed and geared up for below £35,000, thanks partly to a beneficiant donation from Tub alumni.

Lecturers concerned within the building venture are actually urging all universities providing programs in astrophysics to think about investing in an identical construction, as a solution to deliver the topic to life for college kids who would in any other case study stars and deep space nearly completely from lectures and textbooks.

The Tub facility—which is described in a paper printed within the journal Physics Schooling—sports activities a roll-off roof, two high-quality, computer-controlled telescopes and solar panels, and might accommodate two folks at a time. College students use their time within the observatory to assemble information that ties into particular science tasks or modules on their programs.

The 4 authors of the Tub Physics Observatory (BPO) paper, all lecturers within the Division of Physics at Tub who lecture on astrophysics, are coordinator Dr. Peter Sloan, science lead Dr. Vicky Scowcroft, technical lead Dr. Steve Davies and public engagement lead Dr. Gary Mathlin.

Dr. Sloan stated, “We now have over 125 college students enrolled on astrophysics applications, what was lacking was the ability—an observatory—to carry out hands-on observational astrophysics.

“For a few of our college students, there is a disconnect between what they study in lecture theaters and what’s occurring above them within the sky. The observatory provides them an opportunity to see the place their information—star-light—comes from. They nonetheless do onerous science with the info they seize within the observatory, however a venture turns into much more actual and thrilling when calculations come instantly from what’s noticed and photographed by way of a telescope.”

Earlier than building of the observatory, college students gathered information in rather a lot much less consolation. “We might arrange a collapsible tenting desk for college kids to make their observational measurements. By the point they’d completed their night time’s work, that they had ice on their jackets,” stated Dr. Scowcroft.

An necessary goal in offering an observatory was to make star-gazing much less elitist. Explaining, Dr. Scowcroft stated, “A few of our college students have grown up with costly telescopes of their houses, in order that they have an apparent benefit after they get to college. We need to make the expertise of observing the celebrities democratic and accessible to all.”

Dr. Davies added, “We’ve proven that with the arrival of moderate-cost, high-quality, ‘back-garden’ astronomy, and customary computer systems highly effective sufficient to supply authentic analysis, it is potential to construct a small observatory able to precise astrophysical analysis for a modest finances.”

Dr. Mathlin stated, “Round 35 universities within the U.Okay. have their very own observatories however many others do not—we might extremely encourage all locations that train astrophysics to set one up.”

Fred Caudwell, a fourth-year physics student at Tub who focuses on astrophysics, stated, “Plenty of astrophysics at college is about sitting in lectures and fixing issues that you have been given by your tutors—the observatory is what brings the topic to life.”

He added that he couldn’t have undertaken his Grasp’s diploma analysis venture on variable stars (a sort of star that fluctuates in brightness) with out use of the observatory.

“I wanted to make use of a telescope to get the mandatory measurements for my venture however massive telescopes in devoted amenities are extraordinarily costly and in excessive demand, so college students typically do not need entry to them. So the campus observatory was a necessity for me,” he stated.

Lucy Sparkes, who has accomplished the second 12 months of her undergraduate diploma in Physics with Astrophysics and is now on a year-long industrial placement, stated, “In addition to being enjoyable, utilizing the observatory gear final 12 months gave me a extra sensible understanding of how astronomy is completed.

“It was good to have the ability to arrange the telescope through the day, take calibration photos at night time after which use these photos of variable stars and analyze the info I might captured utilizing Python (a pc programming language). All of this has given me a a lot better concept of how the entire astrophysics course of works.”
