Archived Virtual Starry Skies

Meet your presenters!

Sarah Erickson

Hi, I'm Sarah, a sophomore at Colgate from just outside of Chicago. I am an economics and peace and conflict studies double major. A tad different from most of the other presenters, but surprisingly enough the stars have affected several conflicts throughout history. I have worked at the Vis Lab doing science outreach since my freshman year. I enjoy focusing on Greek mythology during my sky talks. As a kid, I grew up reading Greek myths and following the stories within the stars. I love getting to share these stories with the kids who come to the shows and hopefully create an interest in science and learning! I look forward to meeting and talking to you soon!

Leon Nichols

Hello, I'm Leon, a first-year student at Colgate from King of Prussia, Pennsylvania. I began working in the Vis Lab within my first week on campus after I accidentally missed my first astronomy class and then tracked down my professor to apologize. My sky talk focuses on sharing Native American stories about the stars and constellations, some of which I've learned through my Mohawk heritage. While here at Colgate, I intend to major in both Physics and Art, two fields that I have been passionate about since a young age. Working in the Vis Lab has allowed me to further cultivate these interests and I look forward to sharing them with you and nearby communities!

Charlotte (Charlie) Filipovich

Hey there! I’m Charlie, a first-year here at Colgate. I have been part of the Vis Lab team since September 2019. Growing up in Vernon Center, NY (a mere twenty-seven minutes from Colgate), I am no stranger to the light-pollutionless skies of rural CNY. I’m involved with a number of organizations on campus; writing occasionally for The Colgate Maroon-News, participating as a member of Students for the Exploration and Development of Space (SEDS), and working on achieving my dream of becoming a Jedi in Club Fencing. My intended majors are Astronomy/ Physics and Computer Science; making the vis lab the perfect place to learn and implement programming skills and educate others on a subject that I am passionate about. I present various perspectives of astronomy; ranging from tales from civilizations past, weird phenomena we see as observers on Earth, and cosmological happenings from our galaxy and beyond. The most rewarding part of my job is seeing the expression of wonderment on a kid’s face when they discover a world beyond the ‘pale blue dot’ we call home.

Mae Martel

Mae is a Physics major with a minor in Computer Science, and is from Manlius, New York. She began working in the VisLab in her freshman year as a Sky Talk presenter and Outreach tour guide of Colgate’s greenhouse. Mae is passionate about her Chinese heritage, and celebrates the Lunar New Year and Mid-Autumn festival every year through Chinese folk dance and performance of traditional music. Her Sky Talks focus on Chinese astronomy and celestial stories, including the Lunar Houses and Qixi legend. A fun fact about Mae is that despite her dance background, her fingers are so inflexible that they can barely bend backwards a single degree.

Matt Rojas

Anna Cook

“Hi, I’m Anna and I am from Charlotte, North Carolina. Right now, I am planning on majoring in Applied Mathematics and Computer Science— as I find some math proofs pretty and all of them fascinating. I started working for the Vis Lab the first month of my freshman year, and I normally include general knowledge on how to navigate the night sky and the myths associated with the constellations in my sky talks. However, I hopes to expand my sky talks to include different cultures’ interpretations as well as an around the world journey in the coming months! I look forward to meeting you and I love to talk with you all before the shows, so don’t be shy!”



The lab is a handicap-accessible facility on the Colgate University. It is located on the fourth floor of the Robert H.N. Ho Science Center, at the top of the main stairwell.​




The Ho Tung Visualization Laboratory was a special gift to Colgate from Robert H.N. Ho '56 in memory of his grandfather Sir Robert Ho Tung.

Knighted twice by King George V and Queen Elizabeth II, Sir Robert Ho Tung was active as a businessman and philanthropist in the British Crown Colony of Hong Kong. At the September 15, 2007 dedication ceremony for the visualization lab, Mr. Ho quoted a Chinese proverb: "huh shwei, suh yuan" - "Drink water: consider source."

May those who discover new frontiers in this laboratory consider how they can model Sir Robert Ho Tung and Robert H.N. Ho's inspiring words.


The Ho Tung Visualization Lab is a digital planetarium that immerses audience members in stunning visualizations from sliding down a microscope to the far reaches of the cosmos.  Armed with Digistar from Evans & Sutherland, the lab continues to be on the cutting edge of immersive technology.

Dome diameter: 10 meters
