The celestial sphere is a useful model with the Earth at the center, and the sphere of the sky, constellations revolving around it from east to west. In ancient times, people thought that thi was actually the case. Now we know that this only a perception caused by our view of the horizon of a spherical Earth, spinning on its own axis from west to east. Run NAAP app. Then click lab 3. The rotating sky. Click the Rotating sky Explorer, a simula window shows up. For the following questions, use the above simulation launched. Under "star patterns" turn on three constellations, Under location, enter in New York City (40.4 N,73.6 W). Start the animati (you can adjust the speed if you want). 1) From New York City, which constellation is always above the horizon? Always below the hafrizon? Rises and sets below the horizon each day? (final reminder: no one word answer! You answers must be in the form of "A constellation that is always above the horizon from New Yor city is...") 2) From the North Pole (Under location, enter 90 N ), are there constellations that rise above and set below the horizon each day? 3) From the equator (Under location, enter 0N), are there any constellations that are always above the horizon or always below the horizon? 4) At latitudes where Orion rises and sets, in which direction does it set? Does Orion always set in the same direction?
