ANN ARBOR—Omega Centauri appears to be just a group of dots of white light when viewed directly through a telescope. But as an enhanced television image, the largest globular star cluster in the galaxy, Omega Centauri, becomes flecks of red, bursts of yellow and green, and a blinding blue and white light. Through the evolution of technology, these kinds of television images can be captured with the help of a telescope on a mountain in Chile.

Thanks to a program created by University of Michigan astronomers, high school students in Michigan don’t have to visit Chile to get a peek at Omega Centauri. They can simply open their Image of the Month package for a full-color glimpse of astronomical phenomena.

This creative teaching tool is a package of monthly mailings of “Images” of astronomical objects to high school teachers throughout the state. Its editor and chief writer, Prof. Richard Teske, says that “the goal is not to create more astronomers; there are enough already.”

Instead, he and his colleagues believe that “high schools have made an inadequate provision for fostering an interest in astronomy. It is our expectation that ‘Image of the Month’ will bring them a little closer to astronomy as it is currently practiced.”

The mailings include a color 8 inch by 11 inch photograph of a celestial object, a brief discussion about what it is, and sources where more information can be found. The idea of using the pictures was that they would “generate excitement that teachers could use as a hook to grab students’ attention,” explains U-M astronomy Prof. Douglas Richstone. He originated the program with the help of Prof. Hugh Aller, chair of the Department of Astronomy.

Most of the pictures have been taken by U-M faculty with the University’s telescope, operated in Tucson, Ariz., in collaboration with the Massachusetts Institute of Technology and Dartmouth College. They range from pictures of “The Orion Nebula” to pictures of “The Largest Globular Star Cluster in the Galaxy.”

The discussion captions are written by Teske. Many of the mailings also include a profile of a U-M professor who talks about “Why I became an astronomer.”

Lists of magazine articles, books, Internet access, and star charts accompany the pictures. The program also has its own home page and e-mail address where students and teachers can seek answers to astronomical questions.

According to Teske, “Image of the Month” has generated attention from more than just high school students. In the last several months, requests for “Image of the Month” mailings have been received from over 40 new teachers across the state. Teske and his colleagues are pleased with the feedback generated by “Image of the Month.”

“I find this information very useful in my classroom. The students find them really interesting,” says John Holwerda, a Grand Haven teacher. Rey W. Bleisch of the Lansing School District says, “The images I have received to this date have been excellent.”
