WILL-Channel 12's February "Prairie Fire" features a last look at the Vermillion River Observatory south of Danville, where UI scientists charted thousands of new galaxies with a pair of radio telescopes from 1958 to 1980. The show, airing at 8 p.m. Feb. 10, tells the story of the observatory site, carved into a valley by UI professors and students. Abandoned as technology changed and vandals took their toll on equipment, the observatory will be dismantled soon. To return the site to a natural setting, the university plans to remove a 120-foot-wide telescope, which still looms like a flying saucer above the trees. "Prairie Fire" also visits a group of Champaign quilters who gather weekly to continue the art taught to them by their mothers and grandmothers. Host Alison Davis talks with the African-American quilters about the art they fear is dying in their community. The quilters, whose work is on display at the Krannert Art Museum, explain the distinctly African-American improvisation and asymmetry evident in the patterns of their quilts and of those passed down through generations in their families. "Prairie Fire" is Channel 12's monthly cultural magazine series about the people and places of central Illinois.
