Special Exhibits

  Shippee Family Eye Care Butterfly House

The butterfly house is open to the public. Please check in with the front desk in the museum and then head outside to see our free-flying butterflies and plants on display.

  • Currently flying: Monarchs, Painted Ladies, Spicebush Swallowtails, Eastern Black Swallowtail and Red Admirals.

  • This week's butterfly update: One of the spicebush swallowtail caterpillars has pupated or turned into a chrysalis. It went from a bright yellow to a light green color over the course of today. We are expecting a few more caterpillars to do the same by this weekend. Take a look the swallowtail's progress below.

Students captured the arresting images of stars, galaxies, and nebulae in this exhibit.

 

 

"Capturing Starlight: The Art and Science of Astrophotography”

Astrophotography is the photography of objects in space, using specialized equipment to capture light from faraway objects. Even with the use of a powerful telescope and long exposure times, technical post-processing is most often required to view celestial objects in their full grandeur. This process allows us to view interesting features in the universe in ways that our eyes cannot perceive on their own.

 

The images on exhibit were taken and processed by local high school students from St. Johnsbury Academy, White Mountain School, and from the Governor’s Institutes of Vermont on Astronomy, at the Northern Skies Observatory in Peacham, Vermont. The observatory is a state-of-the-art facility that is uniquely located to be free from interference by city lights or suburban light pollution.

 

Students used planetarium programs to identify and locate celestial objects including nebulas, or clouds of gases and dust that will eventually form stars and planets. Observatory educator Brad Vietje worked with students on the photographs included in the new museum exhibit. He explained that students took turns capturing images, which involved target selection, tracking celestial movements, using coordinate systems, operating the computer-controlled telescope, and using imaging software. “Once the monochrome images are captured, they then learn about astronomical image processing… Squeezing detail out of a set of almost black images, they combine three or more filtered grayscale images into a color composite.”

 

Although filtering images means that their colors might not display the same as they would to the naked eye, it allows for the creation of the most perceptible and informative view of an object in space, especially when multiple images are layered together. Just as a filter on a home camera changes the way light and color are viewed, filters such as “Hydrogen Alpha” and “Sulphur II” can make a nebula in space appear magnificent, even amongst the competing light from nearby stars.
