Aside from the moon, a whole multitude of stars, planets, comets and even man-made satellites can be seen with the naked eye on a clear night. With the help of some binoculars or a small telescope, the moons of Jupiter and even spectacular lunar craters can be admired.
The best places to view the night sky are rural or remote locations where light pollution is not a problem. If conditions are good, the Milky Way can be made out as a vast expansive cloudy belt of stars. A sky map is a useful tool to help get oriented and find particular objects or constellations. Closer to the poles, such as in Alaska, beautiful auroras can also be observed. These lights are caused by the ionization of the upper atmosphere by cosmic rays and solar winds.
