Conversely, if we stand on the equator, every star we can see rises and sets. This is just like being on a merry-go-round and looking directly away from it; everything we see enters and then leaves our vision as it rotates around, similar to the rise and fall of the stars. 1 shows that this is caused simply by your location on Earth, and is not a fundamental property of the stars themselves. Going back to the merry-go-round, if we looked up at a 45° angle, some things would never leave our vision, whereas others would enter and leave, just like the stars if we are at a latitude between the North Pole and the Equator.

There are partial, total, and annular solar eclipses. Lunar eclipses are events that take place when Earth passes between the Sun and the Moon, casting a shadow across the surface of the Moon. Because of Earth’s atmosphere, the shadow is often reddish in color. Eclipses don’t just happen here on Earth; we see shadows move across the face of Jupiter cast by its moons, Io, Ganymede, Callisto, or Europa. Eclipses can happen for any planet and moon combination. However, except for one moon of Uranus, no other moon-planet combination makes such perfect eclipses as we have here on Earth.

Using large photographic plates and a special telescope, the program took pictures of the sky over a period of a few years. The plates weigh about a pound each and are delicate, but they give great views of large portions of the sky. Printed versions of the survey also exist, but the most compact form is a set of about 20 CD-ROMs that contain digitally sampled images of all the plates. NATIONAL VIRTUAL OBSERVATORY A new system called the National Virtual Observatory will connect all existing and future sky catalogs and observations.
