Visitors to听Fiske Planetarium听will soon get the chance to feel like they鈥檙e walking on the sun.
Next week, the 抖阴旅行射 Boulder planetarium will debut two new exhibits that explore the inner workings of Earth鈥檚 favorite star. They include an installation that lets anyone stroll through a glowing archway made up of coronal 鈥渓oops鈥濃�攐r the ribbons of blazing-hot plasma that leap from the surface of the sun and can occasionally send solar flares hurtling toward Earth.听
听If you go
Who: Free and open to the public
What:听Collaboration Showcase, featuring exhibits and screening of Climate Change in Our Backyard
When: Tuesday, Feb. 4, 5鈥�6听p.m.
奥丑别谤别:听Fiske Planetarium
The exhibits, which incorporate animations and a lot of LED lights, are the brainchildren of 抖阴旅行射 Boulder graduate and undergraduate students who worked together across a wide range of fields.听
鈥淚t was a really great experience to meet people from so many backgrounds,鈥� said Minso Kim, a PhD student in the Department of Critical Media Practices who took part in that effort. 鈥淓veryone was so enthusiastic to share their talents.鈥�
While the exhibits are already up and ready to view, they鈥檒l get their official launch at an event open to the public on Feb. 4 from 5鈥�6 p.m.听Collaborators on the effort included 抖阴旅行射 Boulder鈥檚 ATLAS Institute听and the National Solar Observatory in Boulder.
That debut will coincide with the first-ever screening of a second project from Fiske: a full-dome film called Climate Change in Our Backyard. This roughly 20-minute feature probes the science behind climate change, its impacts close to home and strategies for addressing those threats. The film was produced in collaboration with students and faculty from the (INSTAAR) and the departments of Geography, Geological Sciences and Astrophysical and Planetary Sciences.听
Both projects were funded by the听抖阴旅行射 Boulder Outreach Awards, which help connect research, teaching and creative work with communities in Colorado and beyond.
鈥淭hese installations are compelling in a different way than a lot of other science exhibits because they really combine science and art,鈥� said Briana Ingermann, the education programs manager for Fiske. 鈥淚 hope that they will inspire visitors to look up information on solar flares and much more.鈥�

Blinking lights
They鈥檙e also the products of years of hard work.
The first of the new solar installations, for example, hangs from the ceiling in Fiske鈥檚 lobby. It鈥檚 a cube made up of 4,100 LED lights that were soldered together with help from SparkFun Electronics. This company, which is based in Colorado, was founded by 抖阴旅行射 Boulder alumnus Nathan Seidle.听
It鈥檚 a colorful lesson in physics: Watch the cube long enough, and you can see colorful flares erupt from the surface of the sun, then go crashing into Earth鈥檚 magnetic field.听
鈥淭his is an epic project,鈥� said John Keller, director of the Fiske Planetarium.
Keller explained that the idea of the cube first emerged out of a one-of-a-kind class held in spring 2019. The course, called 鈥淪tudio: Design an Immersive Science Exhibit,鈥� included instructors Keller and Ingermann from Fiske, Mark Gross, Annie Bruns and Wayne Seltzer from ATLAS and Claire Raftery from the National Solar Observatory.
It brought together 20 undergraduate students from several disciplines and set them on an unusual charge鈥攖o come up with fun ways for people of all ages to learn about the sun.听
Graduate student Kim was one of the team members who worked on听the second of those exhibits, an installation dubbed the Solar Arcade. She said her group wanted the project to dive into the strange behavior of the sun鈥檚 contorting magnetic fields.听
And what better way to do that than to let visitors walk among those field lines on the surface of the sun itself?
鈥淚鈥檓 interested in making people feel like they鈥檙e somewhere else,鈥� Kim said. 鈥淭hat can mean giving people the chance to be in an impossible place.鈥�
Sharing ideas
You can鈥檛 miss the group's own impossible place in the middle of Fiske鈥檚 lobby. It鈥檚 the exhibit that looks a bit like a dance rave version of a garden walkway.
Kim added that the final product couldn鈥檛 have come together without the work of the听whole team, which included five students studying everything from communications to computer science.
Keller agreed, noting that the new installations are proof of what students can do when they work together.
鈥淚 was most impressed with the level of collaboration and idea-sharing from the members of the class,鈥� Keller said. 鈥淚t was a cross-pollination of ideas that was so much richer than anything we imagined.鈥�
