The world was abuzz about the return of Comet C/2022 E3 (ZTF) to the solar system, and the Atchison community was no different. Hundreds of people turned out for each of two planned viewings of the "Green Comet," a visitor from deep space that only passes Earth once every 50,000 years! The rare appearance put its viewing on the bucket list for many Benedictine College students, faculty, staff and area residents. The comet was not as bright as predicted, so the use of a telescope was necessary to see the dramatic, once-in-a-lifetime sight.

To help with the viewing, the Benedictine College Department of Physics & Astronomy hosted two open houses at the school’s Daglen Observatory. At the first open house on January 30, 2023, low clouds obscurred the comet, but visitors enjoyed looking at Jupiter and the Moon. A crystal clear night welcomed the long line of visitors for the second open house on February 2, 2023, and the result was not disappointing. Telescopes were trained on the comet for personal viewing and the observatory even tried to get a picture of the comet.

Built in 2017, the Daglen Observatory is part of the Vatican Observatory Consortium and was funded by a gift from Joe ’69 and Frankee Wright ’69 Daglen. It has four large 14-inch telescopes, plus a control room where images from the telescopes can be viewed on monitors. This will allow visitors plenty of opportunity to view the comet and other celestial bodies.

“The comet made its closest approach to Earth on February 1, but we had hoped that the January 30 date would allow a better view since the Moon was not as bright, plus there was a close conjunction of Mars and the Moon, adding to the spectacle of the night,” said Dr. Ryan Maderak, chair of the Department of Physics & Astronomy. He added that the opportunity to view Jupiter and Uranus was a plus on either night.

Dr. Maderak and Dr. Christopher Shingledecker, assistant professor in the department, will run the open house with assistance from students who are astronomy majors or part of the Physics Club.

Shingledecker is a noted specialist on comets who was part of an international team of astronomers among the first to use NASA’s new James Webb Space Telescope. He has written an article on the chemical makeup of comets and was recently quoted in Our Sunday Visitor in reference to C/2022 E3 (ZTF), called the “green comet.”
