CSO
Booth on AstroDay 2006 
AstoDay 2006 was
held on
6th of May 2006. At the CSO booth, we had a
CSO telescope art project, and a small parabolic dish
demonstration to show how a telescope collect radiation from distant
astronomical objects. Both activities were very successful
throughout the day. We found many kids and
adults who enjoyed activities on the CSO booth and who showed strong
interests in science. For the art project, about 200
kids and
adults made their decorations. For the small parabolic dish
demonstration, by dropping a ping-pong ball down on the good surface of
the
parabolic dish which sat against the gravity, people learned the ball
was bounced up at the focus position always. Therefore, people
understood how
radiation is reflected on the surface of the dish and sent to our
sensitive detectors and cameras to make maps/images of
stars, molecular clouds, galaxies, and so on in high sensitivity.
Also, people
understood how important a smooth surface of the primary dish and
following mirrors would be for the high efficiency of a telescope.
The 1.2 m parabolic dish, which
was used for the demonstration, was donated by Oceanic Time Warner
Cable located in Hilo. We are so grateful for their warm hearted
donation and their support for our public educational outreach efforts.
