Distance scales that are meaningful to us in our daily life fall short when talking about distances to the planets and beyond. In this show we'll look at how astronomical distances compare to those we use in our everyday life and learn why astronomers use distance scales so different than those we may be familiar with. In addition we'll see how astronomers measure astronomical distances and how they may relate to our perception of space and time.

The year was 1680 when one of the brightest comets in recorded history was seen in the daytime. History may be repeated this winter when a comet named ISON passes through our inner solar system. ISON, a sun grazing comet, appears to follow the same path through space as the Great Comet of 1680 and may well be another chunk of the material that formed the 1680 comet. In addition to learning about comet ISON we'll look back in history to discover other visitors to our inner solar system and find the evidence of some that collided with Earth.

Some 900 extra-solar planets have been found in orbit around 700 plus stars. The Kepler Mission has detected over 18,000 additional transits of which over 260 may be habitable planets. Based on these data it is estimated that there are between 100 and 400 billion planets orbiting around other stars in the Milky Way Galaxy. How are these extra-solar planets detected, what is labeled a "habitable planet", what conditions would astrobiologists consider supportive of extra-solar life? We'll address these questions as we explore planets and life beyond Earth.

It is not difficult to imagine being out under clear skies on warm summer nights; the bright glow of the Milky Way high overhead, the faint glow of mysterious deep space objects, and the magical attraction of predominate stars and stellar patterns. Come along; join us, as we take you on this traditional planetarium show tour. We'll take imaginary trips out to fascinating places in deep space for a closer look at famous clusters, nebulae, and stars across the summer sky.
