Hubble Images at Mueller Planetarium Martin Gaskell, senior lecturer in physics and astronmy at UNL discusses Whirlpool Galaxy M51 during the unveling of Hubble Space Telescope images at Mueller Planetarium on April 25. In honor of Hubble's 15th anniversary, two posters of space telescope photos were given to Mueller Planetarium to display within Morrill Hall. The other image is of Eagle Nebula M16, showcasing a 9.5-ightyear tall, dense tower of gas that is being formed by ultraviolet light from a group of massive, hot stars. The planetarium is among 100 science centers across the country, from Guam to Maine that will display the mural-size images. Lincoln Mayor Coleen Seng, Chancellor Harvey Perlman and other university officials were on hand for the unveiling. Photo by Troy Fedderson, University Communications.
