![]() ![]() The first lens is called the objective lens. ![]() The basic refracting telescope has two lenses. You can go here to learn more about the refraction of light using lenses. Refracting telescopes use lenses to bend the light to a specific focal point such that the object will be magnified to the viewer. These telescopes are called reflecting telescopes. The other type uses mirrors to focus the light of the image. Telescopes that use lenses are called refracting telescopes. One type uses lenses to magnify the image. Magnification - The magnification of a telescope describes how much larger the telescope can make objects appear.The larger the aperture, the more light the telescope can gather. This feature is usually determined by the size of the aperture of the telescope. Light gathering ability - The better a telescope can gather light, the better you will be able to see far away stars and faint objects in the night sky.Parking is available at the observatory.The two most important properties of a telescope are: Media are invited to attend.ĭyer Observatory is located in Brentwood at 1000 Oman Drive, just off Granny White Pike. Friday, July 26, and will last approximately 45 minutes. This year’s camps were made possible by a joint collaboration of three separate research programs. The camps are chiefly funded by the Space Telescope Science Institute, the NASA organization that operates the Hubble telescope, through education/public outreach grants that are made possible by researchers who have had successful HST proposals. These grants support efforts across the country to bring STEM education to underserved middle-schoolers and promote ongoing scientific engagement outside of school. Space and Rocket Center in Huntsville, Ala., are funded in part by a NASA Summer of Innovation grant.

Before Hubble’s discovery, “many thought the entire universe consisted only of the Milky Way and was about 300,000 light years in diameter,” explained Alvey. Part of Hubble’s calculations were based on a galaxy first described by Vanderbilt astronomer E. In addition to O’Dell, Hubble shares another connection with Vanderbilt: In 1924, the telescope’s namesake, Edwin Hubble, confirmed that the universe was much bigger than anyone realized. When each model is complete, campers will be able to remotely aim it and take a photograph. The actual Hubble Space Telescope (HST) is about the size of a large city bus the models will be about three and a half feet long. Not only are they assembling the moving parts, but they are also wiring the electronics and programing the chips. The core project of this year’s camp is the building of a functioning 1/12-scale model of Hubble complete with an optical system, camera, solar panels, steering system, and wrapped in a Mylar skin. The campers have also been learning from some of Vanderbilt’s top astronomers, including O’Dell and David Weintraub, professor of astronomy. Campers have been learning how telescopes work and, since Dyer’s own telescope cannot be used during the day, campers are logging into telescopes located in Europe and Australia where it’s already night. With the theme “Understanding Hubble,” this year’s sessions focus on the tools astronomers use to study the universe. (Joe Howell/Vanderbilt University)ĭyer’s space camps have long been popular with local kids who want to learn more about the final frontier but last year, the Dyer Observatory staff noticed that the campers didn’t know much about one of the most important tools of the trade.ĭyer Observatory director Rocky Alvey, outreach astronomer Billy Teets and volunteer Bob Schwiekert wanted to change that. Volunteer Bob Schweikert and counselors Brent Ritter Nash Beasley work with campers on a model of the HST. (Bob) O’Dell, now Distinguished Research Professor of Astrophysics at Vanderbilt. On Friday, they’ll demonstrate the telescopes, accompanied by a presentation by Hubble’s founding project scientist C. Nashville-area middle-schoolers attending Dyer Observatory’s space camp are spending some time this summer building functioning scale models of the Hubble Space Telescope.
