Lab Report 1: Sky Maps and the Celestial Sphere Introduction The purpose of this lab was to become familiar with the celestial sphere and the accompanying methods of operation. The required skills included the celestial coordinate system, which allows users to locate objects on the celestial sphere, estimating coordinates of objects on the celestial sphere, visualize where objects rise and set, and compare Detroit’s sky to other area’s skies. The lab also introduced methods of measurement used by the celestial sphere, using both Earth coordinates (latitude and longitude), and celestial coordinates (declination and right ascension). Conclusion With few exceptions, our results were very similar to the expected results in the lab manual. There was error when calculating the declination of Arcturus in Part B, skewing our results by 90 degrees. This error was the result of using the incorrect scale to determine degrees. We used the scale which corresponded with longitude, as the declination scale had the label

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
