Heaven made light show!

            The aurora, or northern and southern lights, are often visible from the surface of the Earth at high northern or southern latitudes. Auroras typically appear as luminous bands or streamers that can extend to altitudes of 200 miles (well into the ionosphere).

       Stars do not actually twinkle when viewed from outer space. They appear to twinkle when we see them from the Earth's surface because we are viewing them through thick layers of moving air in the Earth's atmosphere.
